CloudWatch.Client¶A low-level client representing Amazon CloudWatch
Amazon CloudWatch monitors your Amazon Web Services (Amazon Web Services) resources and the applications you run on Amazon Web Services in real time. You can use CloudWatch to collect and track metrics, which are the variables you want to measure for your resources and applications.
CloudWatch alarms send notifications or automatically change the resources you are monitoring based on rules that you define. For example, you can monitor the CPU usage and disk reads and writes of your Amazon EC2 instances. Then, use this data to determine whether you should launch additional instances to handle increased load. You can also use this data to stop under-used instances to save money.
In addition to monitoring the built-in metrics that come with Amazon Web Services, you can monitor your own custom metrics. With CloudWatch, you gain system-wide visibility into resource utilization, application performance, and operational health.

create_foo, and you'd normally invoke the
operation as client.create_foo(**kwargs), if the
create_foo operation can be paginated, you can use the
call client.get_paginator("create_foo").True if the operation can be paginated,
False otherwise.close()¶Closes underlying endpoint connections.
delete_alarms(**kwargs)¶Deletes the specified alarms. You can delete up to 100 alarms in one operation. However, this total can include no more than one composite alarm. For example, you could delete 99 metric alarms and one composite alarms with one operation, but you can't delete two composite alarms with one operation.
In the event of an error, no alarms are deleted.
Note
It is possible to create a loop or cycle of composite alarms, where composite alarm A depends on composite alarm B, and composite alarm B also depends on composite alarm A. In this scenario, you can't delete any composite alarm that is part of the cycle because there is always still a composite alarm that depends on that alarm that you want to delete.
To get out of such a situation, you must break the cycle by changing the rule of one of the composite alarms in the cycle to remove a dependency that creates the cycle. The simplest change to make to break a cycle is to change the AlarmRule of one of the alarms to False .
Additionally, the evaluation of composite alarms stops if CloudWatch detects a cycle in the evaluation path.

The metric dimensions associated with the anomaly detection model to delete.
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
A single metric anomaly detector to be deleted.
When using SingleMetricAnomalyDetector , you cannot include the following parameters in the same operation:
Dimensions ,MetricNameNamespaceStatMetricMathAnomalyDetector parameters of DeleteAnomalyDetectorInputInstead, specify the single metric anomaly detector attributes as part of the SingleMetricAnomalyDetector property.
The namespace of the metric to create the anomaly detection model for.

The metric math anomaly detector to be deleted.
When using MetricMathAnomalyDetector , you cannot include following parameters in the same operation:
Dimensions ,MetricNameNamespaceStatSingleMetricAnomalyDetector parameters of DeleteAnomalyDetectorInputInstead, specify the metric math anomaly detector attributes as part of the MetricMathAnomalyDetector property.
An array of metric data query structures that enables you to create an anomaly detector based on the result of a metric math expression. Each item in MetricDataQueries gets a metric or performs a math expression. One item in MetricDataQueries is the expression that provides the time series that the anomaly detector uses as input. Designate the expression by setting ReturnData to True for this object in the array. For all other expressions and metrics, set ReturnData to False . The designated expression must return a single time series.
This structure is used in both GetMetricData and PutMetricAlarm . The supported use of this structure is different for those two operations.
When used in GetMetricData , it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A single GetMetricData call can include up to 500 MetricDataQuery structures.
When used in PutMetricAlarm , it enables you to create an alarm based on a metric math expression. Each MetricDataQuery in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics. A single PutMetricAlarm call can include up to 20 MetricDataQuery structures in the array. The 20 structures can include as many as 10 structures that contain a MetricStat parameter to retrieve a metric, and as many as 10 structures that contain the Expression parameter to perform a math expression. Of those Expression structures, one must have True as the value for ReturnData . The result of this expression is the value the alarm watches.
Any expression used in a PutMetricAlarm operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Some of the parameters of this structure also have different uses whether you are using this structure in a GetMetricData operation or a PutMetricAlarm operation. These differences are explained in the following parameter list.
A short name used to tie this object to the results in the response. This name must be unique within a single call to GetMetricData . If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.
The metric to return, including the metric name, namespace, and dimensions.
The namespace of the metric.
The name of the metric. This is a required field.
The dimensions for the metric.
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
The statistic to return. It can include any CloudWatch statistic or extended statistic.
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, if you omit Unit then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.
This field can contain either a Metrics Insights query, or a metric math expression to be performed on the returned data. For more information about Metrics Insights queries, see Metrics Insights query components and syntax in the Amazon CloudWatch User Guide .
A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
When used in GetMetricData , this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specify False . If you omit this, the default of True is used.
When used in PutMetricAlarm , specify True for the one expression result to use as the alarm. For all other metrics and expressions in the same PutMetricAlarm operation, specify ReturnData as False.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData operation that includes a StorageResolution of 1 second .
The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.

An array of MetricDataQuery structures, used in an alarm based on a metric math expression. Each structure either retrieves a metric or performs a math expression. One item in the Metrics array is the math expression that the alarm watches. This expression by designated by having ReturnData set to true.
(dict) --
This structure is used in both GetMetricData and PutMetricAlarm . The supported use of this structure is different for those two operations.
When used in GetMetricData , it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A single GetMetricData call can include up to 500 MetricDataQuery structures.
When used in PutMetricAlarm , it enables you to create an alarm based on a metric math expression. Each MetricDataQuery in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics. A single PutMetricAlarm call can include up to 20 MetricDataQuery structures in the array. The 20 structures can include as many as 10 structures that contain a MetricStat parameter to retrieve a metric, and as many as 10 structures that contain the Expression parameter to perform a math expression. Of those Expression structures, one must have True as the value for ReturnData . The result of this expression is the value the alarm watches.
Any expression used in a PutMetricAlarm operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Some of the parameters of this structure also have different uses whether you are using this structure in a GetMetricData operation or a PutMetricAlarm operation. These differences are explained in the following parameter list.
Id (string) --
A short name used to tie this object to the results in the response. This name must be unique within a single call to GetMetricData . If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.
MetricStat (dict) --
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.
Metric (dict) --
The metric to return, including the metric name, namespace, and dimensions.
Namespace (string) --
The namespace of the metric.
MetricName (string) --
The name of the metric. This is a required field.
Dimensions (list) --
The dimensions for the metric.
(dict) --
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
Name (string) --
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
Value (string) --
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
Period (integer) --
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
Stat (string) --
The statistic to return. It can include any CloudWatch statistic or extended statistic.
Unit (string) --
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, if you omit Unit then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.
Expression (string) --
This field can contain either a Metrics Insights query, or a metric math expression to be performed on the returned data. For more information about Metrics Insights queries, see Metrics Insights query components and syntax in the Amazon CloudWatch User Guide .
A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.
Label (string) --
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
ReturnData (boolean) --
When used in GetMetricData , this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specify False . If you omit this, the default of True is used.
When used in PutMetricAlarm , specify True for the one expression result to use as the alarm. For all other metrics and expressions in the same PutMetricAlarm operation, specify ReturnData as False.
Period (integer) --
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData operation that includes a StorageResolution of 1 second .
AccountId (string) --
The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.
ThresholdMetricId (string) --
In an alarm based on an anomaly detection model, this is the ID of the ANOMALY_DETECTION_BAND function used as the threshold for the alarm.
NextToken (string) --
The token that marks the start of the next batch of returned results.
Exceptions
CloudWatch.Client.exceptions.InvalidNextTokendescribe_alarms_for_metric(**kwargs)¶Retrieves the alarms for the specified metric. To filter the results, specify a statistic, period, or unit.
This operation retrieves only standard alarms that are based on the specified metric. It does not return alarms based on math expressions that use the specified metric, or composite alarms that use the specified metric.

Of those Expression structures, one must have True as the value for ReturnData . The result of this expression is the value the alarm watches.
Any expression used in a PutMetricAlarm operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Some of the parameters of this structure also have different uses whether you are using this structure in a GetMetricData operation or a PutMetricAlarm operation. These differences are explained in the following parameter list.
Id (string) --
A short name used to tie this object to the results in the response. This name must be unique within a single call to GetMetricData . If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.
MetricStat (dict) --
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.
Metric (dict) --
The metric to return, including the metric name, namespace, and dimensions.
Namespace (string) --
The namespace of the metric.
MetricName (string) --
The name of the metric. This is a required field.
Dimensions (list) --
The dimensions for the metric.
(dict) --
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
Name (string) --
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
Value (string) --
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
Period (integer) --
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
Stat (string) --
The statistic to return. It can include any CloudWatch statistic or extended statistic.
Unit (string) --
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, if you omit Unit then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.
Expression (string) --
This field can contain either a Metrics Insights query, or a metric math expression to be performed on the returned data. For more information about Metrics Insights queries, see Metrics Insights query components and syntax in the Amazon CloudWatch User Guide .
A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.
Label (string) --
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
ReturnData (boolean) --
When used in GetMetricData , this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specify False . If you omit this, the default of True is used.
When used in PutMetricAlarm , specify True for the one expression result to use as the alarm. For all other metrics and expressions in the same PutMetricAlarm operation, specify ReturnData as False.
Period (integer) --
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData operation that includes a StorageResolution of 1 second .
AccountId (string) --
The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.
NextToken (string) --
A token that you can use in a subsequent operation to retrieve the next set of results.

Exceptions
CloudWatch.Client.exceptions.InvalidParameterValueExceptionCloudWatch.Client.exceptions.MissingRequiredParameterExceptionCloudWatch.Client.exceptions.ResourceNotFoundExceptionget_metric_data(**kwargs)¶You can use the GetMetricData API to retrieve CloudWatch metric values. The operation can also include a CloudWatch Metrics Insights query, and one or more metric math functions.
A GetMetricData operation that does not include a query can retrieve as many as 500 different metrics in a single request, with a total of as many as 100,800 data points. You can also optionally perform metric math expressions on the values of the returned statistics, to create new time series that represent new insights into your data. For example, using Lambda metrics, you could divide the Errors metric by the Invocations metric to get an error rate time series. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
If you include a Metrics Insights query, each GetMetricData operation can include only one query. But the same GetMetricData operation can also retrieve other metrics. Metrics Insights queries can query only the most recent three hours of metric data. For more information about Metrics Insights, see Query your metrics with CloudWatch Metrics Insights .
Calls to the GetMetricData API have a different pricing structure than calls to GetMetricStatistics . For more information about pricing, see Amazon CloudWatch Pricing .
Amazon CloudWatch retains metric data as follows:
StorageResolution of 1.Data points that are initially published with a shorter period are aggregated together for long-term storage. For example, if you collect data using a period of 1 minute, the data remains available for 15 days with 1-minute resolution. After 15 days, this data is still available, but is aggregated and retrievable only with a resolution of 5 minutes. After 63 days, the data is further aggregated and is available with a resolution of 1 hour.
If you omit Unit in your request, all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.
Using Metrics Insights queries with metric math
You can't mix a Metric Insights query and metric math syntax in the same expression, but you can reference results from a Metrics Insights query within other Metric math expressions. A Metrics Insights query without a GROUP BY clause returns a single time-series (TS), and can be used as input for a metric math expression that expects a single time series. A Metrics Insights query with a GROUP BY clause returns an array of time-series (TS[]), and can be used as input for a metric math expression that expects an array of time series.

[REQUIRED]
The metric queries to be returned. A single GetMetricData call can include as many as 500 MetricDataQuery structures. Each of these structures can specify either a metric to retrieve, a Metrics Insights query, or a math expression to perform on retrieved data.
This structure is used in both GetMetricData and PutMetricAlarm . The supported use of this structure is different for those two operations.
When used in GetMetricData , it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A single GetMetricData call can include up to 500 MetricDataQuery structures.
When used in PutMetricAlarm , it enables you to create an alarm based on a metric math expression. Each MetricDataQuery in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics. A single PutMetricAlarm call can include up to 20 MetricDataQuery structures in the array. The 20 structures can include as many as 10 structures that contain a MetricStat parameter to retrieve a metric, and as many as 10 structures that contain the Expression parameter to perform a math expression. Of those Expression structures, one must have True as the value for ReturnData . The result of this expression is the value the alarm watches.
Any expression used in a PutMetricAlarm operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Some of the parameters of this structure also have different uses whether you are using this structure in a GetMetricData operation or a PutMetricAlarm operation. These differences are explained in the following parameter list.
A short name used to tie this object to the results in the response. This name must be unique within a single call to GetMetricData . If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.
The metric to return, including the metric name, namespace, and dimensions.
The namespace of the metric.
The name of the metric. This is a required field.
The dimensions for the metric.
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
The statistic to return. It can include any CloudWatch statistic or extended statistic.
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, if you omit Unit then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.

A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
When used in GetMetricData , this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specify False . If you omit this, the default of True is used.
When used in PutMetricAlarm , specify True for the one expression result to use as the alarm. For all other metrics and expressions in the same PutMetricAlarm operation, specify ReturnData as False.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData operation that includes a StorageResolution of 1 second .
The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.
[REQUIRED]
The time stamp indicating the earliest data to be returned.
The value specified is inclusive; results include data points with the specified time stamp.
CloudWatch rounds the specified time stamp as follows:
If you set Period to 5, 10, or 30, the start time of your request is rounded down to the nearest time that corresponds to even 5-, 10-, or 30-second divisions of a minute. For example, if you make a query at (HH:mm:ss) 01:05:23 for the previous 10-second period, the start time of your request is rounded down and you receive data from 01:05:10 to 01:05:20. If you make a query at 15:07:17 for the previous 5 minutes of data, using a period of 5 seconds, you receive data timestamped between 15:02:15 and 15:07:15.
For better performance, specify StartTime and EndTime values that align with the value of the metric's Period and sync up with the beginning and end of an hour. For example, if the Period of a metric is 5 minutes, specifying 12:05 or 12:30 as StartTime can get a faster response from CloudWatch than setting 12:07 or 12:29 as the StartTime .
[REQUIRED]
The time stamp indicating the latest data to be returned.
The value specified is exclusive; results include data points up to the specified time stamp.
For better performance, specify StartTime and EndTime values that align with the value of the metric's Period and sync up with the beginning and end of an hour. For example, if the Period of a metric is 5 minutes, specifying 12:05 or 12:30 as EndTime can get a faster response from CloudWatch than setting 12:07 or 12:29 as the EndTime .
GetMetricData operation, to get the next set of data points.TimestampDescending returns the newest data first and paginates when the MaxDatapoints limit is reached. TimestampAscending returns the oldest data first and paginates when the MaxDatapoints limit is reached.This structure includes the Timezone parameter, which you can use to specify your time zone so that the labels of returned data display the correct time for your time zone.
The time zone to use for metric data return in this operation. The format is + or - followed by four digits. The first two digits indicate the number of hours ahead or behind of UTC, and the final two digits are the number of minutes. For example, +0130 indicates a time zone that is 1 hour and 30 minutes ahead of UTC. The default is +0000.

CloudWatch.Client.exceptions.InvalidNextTokenget_metric_statistics(**kwargs)¶Gets statistics for the specified metric.
The maximum number of data points returned from a single call is 1,440. If you request more than 1,440 data points, CloudWatch returns an error. To reduce the number of data points, you can narrow the specified time range and make multiple requests across adjacent time ranges, or you can increase the specified period. Data points are not returned in chronological order.
CloudWatch aggregates data points based on the length of the period that you specify. For example, if you request statistics with a one-hour period, CloudWatch aggregates all data points with time stamps that fall within each one-hour period. Therefore, the number of values aggregated by CloudWatch is larger than the number of data points returned.
CloudWatch needs raw data points to calculate percentile statistics. If you publish data using a statistic set instead, you can only retrieve percentile statistics for this data if one of the following conditions is true:
Percentile statistics are not available for metrics when any of the metric values are negative numbers.
Amazon CloudWatch retains metric data as follows:
StorageResolution of 1.Data points that are initially published with a shorter period are aggregated together for long-term storage. For example, if you collect data using a period of 1 minute, the data remains available for 15 days with 1-minute resolution. After 15 days, this data is still available, but is aggregated and retrievable only with a resolution of 5 minutes. After 63 days, the data is further aggregated and is available with a resolution of 1 hour.
CloudWatch started retaining 5-minute and 1-hour metric data as of July 9, 2016.
For information about metrics and dimensions supported by Amazon Web Services services, see the Amazon CloudWatch Metrics and Dimensions Reference in the Amazon CloudWatch User Guide .

)
[REQUIRED]
The namespace of the metric, with or without spaces.
[REQUIRED]
The name of the metric, with or without spaces.
The dimensions. If the metric contains multiple dimensions, you must include a value for each dimension. CloudWatch treats each unique combination of dimensions as a separate metric. If a specific combination of dimensions was not published, you can't retrieve statistics for it. You must specify the same dimensions that were used when the metrics were created. For an example, see Dimension Combinations in the Amazon CloudWatch User Guide . For more information about specifying dimensions, see Publishing Metrics in the Amazon CloudWatch User Guide .
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
[REQUIRED]
The time stamp that determines the first data point to return. Start times are evaluated relative to the time that CloudWatch receives the request.
The value specified is inclusive; results include data points with the specified time stamp. In a raw HTTP query, the time stamp must be in ISO 8601 UTC format (for example, 2016-10-03T23:00:00Z).
CloudWatch rounds the specified time stamp as follows:
If you set Period to 5, 10, or 30, the start time of your request is rounded down to the nearest time that corresponds to even 5-, 10-, or 30-second divisions of a minute. For example, if you make a query at (HH:mm:ss) 01:05:23 for the previous 10-second period, the start time of your request is rounded down and you receive data from 01:05:10 to 01:05:20. If you make a query at 15:07:17 for the previous 5 minutes of data, using a period of 5 seconds, you receive data timestamped between 15:02:15 and 15:07:15.
[REQUIRED]
The time stamp that determines the last data point to return.
The value specified is exclusive; results include data points up to the specified time stamp. In a raw HTTP query, the time stamp must be in ISO 8601 UTC format (for example, 2016-10-10T23:00:00Z).
[REQUIRED]
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
The metric statistics, other than percentile. For percentile statistics, use ExtendedStatistics . When calling GetMetricStatistics , you must specify either Statistics or ExtendedStatistics , but not both.
The percentile statistics. Specify values between p0.0 and p100. When calling GetMetricStatistics , you must specify either Statistics or ExtendedStatistics , but not both. Percentile statistics are not available for metrics when any of the metric values are negative numbers.
Unit , all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.dict

The configuration specifies details about how the anomaly detection model is to be trained, including time ranges to exclude when training and updating the model. You can specify as many as 10 time ranges.
The configuration can also include the time zone to use for the metric.
An array of time ranges to exclude from use when the anomaly detection model is trained. Use this to make sure that events that could cause unusual values for the metric, such as deployments, aren't used when CloudWatch creates the model.
Specifies one range of days or times to exclude from use for training an anomaly detection model.
The start time of the range to exclude. The format is yyyy-MM-dd'T'HH:mm:ss . For example, 2019-07-01T23:59:59 .
The end time of the range to exclude. The format is yyyy-MM-dd'T'HH:mm:ss . For example, 2019-07-01T23:59:59 .
The time zone to use for the metric. This is useful to enable the model to automatically account for daylight savings time changes if the metric is sensitive to such time changes.
To specify a time zone, use the name of the time zone as specified in the standard tz database. For more information, see tz database .

The designated expression must return a single time series.
This structure is used in both GetMetricData and PutMetricAlarm . The supported use of this structure is different for those two operations.
When used in GetMetricData , it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A single GetMetricData call can include up to 500 MetricDataQuery structures.
When used in PutMetricAlarm , it enables you to create an alarm based on a metric math expression. Each MetricDataQuery in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics. A single PutMetricAlarm call can include up to 20 MetricDataQuery structures in the array. The 20 structures can include as many as 10 structures that contain a MetricStat parameter to retrieve a metric, and as many as 10 structures that contain the Expression parameter to perform a math expression. Of those Expression structures, one must have True as the value for ReturnData . The result of this expression is the value the alarm watches.
Any expression used in a PutMetricAlarm operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Some of the parameters of this structure also have different uses whether you are using this structure in a GetMetricData operation or a PutMetricAlarm operation. These differences are explained in the following parameter list.
A short name used to tie this object to the results in the response. This name must be unique within a single call to GetMetricData . If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.
The metric to return, including the metric name, namespace, and dimensions.
The namespace of the metric.
The name of the metric. This is a required field.
The dimensions for the metric.
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
The statistic to return. It can include any CloudWatch statistic or extended statistic.
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, if you omit Unit then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.
This field can contain either a Metrics Insights query, or a metric math expression to be performed on the returned data. For more information about Metrics Insights queries, see Metrics Insights query components and syntax in the Amazon CloudWatch User Guide .
A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
When used in GetMetricData , this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specify False . If you omit this, the default of True is used.
When used in PutMetricAlarm , specify True for the one expression result to use as the alarm. For all other metrics and expressions in the same PutMetricAlarm operation, specify ReturnData as False.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData operation that includes a StorageResolution of 1 second .
The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.

CloudWatch.Client.exceptions.LimitExceededExceptionCloudWatch.Client.exceptions.InternalServiceFaultCloudWatch.Client.exceptions.InvalidParameterValueExceptionCloudWatch.Client.exceptions.MissingRequiredParameterExceptionCloudWatch.Client.exceptions.InvalidParameterCombinationExceptionput_composite_alarm(**kwargs)¶Creates or updates a composite alarm . When you create a composite alarm, you specify a rule expression for the alarm that takes into account the alarm states of other alarms that you have created. The composite alarm goes into ALARM state only if all conditions of the rule are met.
The alarms specified in a composite alarm's rule expression can include metric alarms and other composite alarms. The rule expression of a composite alarm can include as many as 100 underlying alarms. Any single alarm can be included in the rule expressions of as many as 150 composite alarms.
Using composite alarms can reduce alarm noise. You can create multiple metric alarms, and also create a composite alarm and set up alerts only for the composite alarm. For example, you could create a composite alarm that goes into ALARM state only when more than one of the underlying metric alarms are in ALARM state.
Currently, the only alarm actions that can be taken by composite alarms are notifying SNS topics.
Note
It is possible to create a loop or cycle of composite alarms, where composite alarm A depends on composite alarm B, and composite alarm B also depends on composite alarm A. In this scenario, you can't delete any composite alarm that is part of the cycle because there is always still a composite alarm that depends on that alarm that you want to delete.
To get out of such a situation, you must break the cycle by changing the rule of one of the composite alarms in the cycle to remove a dependency that creates the cycle. The simplest change to make to break a cycle is to change the AlarmRule of one of the alarms to False .
Additionally, the evaluation of composite alarms stops if CloudWatch detects a cycle in the evaluation path.
When this operation creates an alarm, the alarm state is immediately set to INSUFFICIENT_DATA . The alarm is then evaluated and its state is set appropriately. Any actions associated with the new state are then executed. For a composite alarm, this initial time after creation is the only time that the alarm can be in INSUFFICIENT_DATA state.
When you update an existing alarm, its state is left unchanged, but the update completely overwrites the previous configuration of the alarm.
To use this operation, you must be signed on with the cloudwatch:PutCompositeAlarm permission that is scoped to * . You can't create a composite alarms if your cloudwatch:PutCompositeAlarm permission has a narrower scope.
If you are an IAM user, you must have iam:CreateServiceLinkedRole to create a composite alarm that has Systems Manager OpsItem actions.

Valid Values: ``arn:aws:sns:region :account-id :sns-topic-name `` | ``arn:aws:ssm:region :account-id :opsitem:severity ``
[REQUIRED]
The name for the composite alarm. This name must be unique within the Region.
[REQUIRED]
An expression that specifies which other alarms are to be evaluated to determine this composite alarm's state. For each alarm that you reference, you designate a function that specifies whether that alarm needs to be in ALARM state, OK state, or INSUFFICIENT_DATA state. You can use operators (AND, OR and NOT) to combine multiple functions in a single expression. You can use parenthesis to logically group the functions in your expression.
You can use either alarm names or ARNs to reference the other alarms that are to be evaluated.
Functions can include the following:
ALARM("*alarm-name* or *alarm-ARN* ") is TRUE if the named alarm is in ALARM state.OK("*alarm-name* or *alarm-ARN* ") is TRUE if the named alarm is in OK state.INSUFFICIENT_DATA("*alarm-name* or *alarm-ARN* ") is TRUE if the named alarm is in INSUFFICIENT_DATA state.TRUE always evaluates to TRUE.FALSE always evaluates to FALSE.TRUE and FALSE are useful for testing a complex AlarmRule structure, and for testing your alarm actions.
Alarm names specified in AlarmRule can be surrounded with double-quotes ("), but do not have to be.
The following are some examples of AlarmRule :
ALARM(CPUUtilizationTooHigh) AND ALARM(DiskReadOpsTooHigh) specifies that the composite alarm goes into ALARM state only if both CPUUtilizationTooHigh and DiskReadOpsTooHigh alarms are in ALARM state.ALARM(CPUUtilizationTooHigh) AND NOT ALARM(DeploymentInProgress) specifies that the alarm goes to ALARM state if CPUUtilizationTooHigh is in ALARM state and DeploymentInProgress is not in ALARM state. This example reduces alarm noise during a known deployment window.(ALARM(CPUUtilizationTooHigh) OR ALARM(DiskReadOpsTooHigh)) AND OK(NetworkOutTooHigh) goes into ALARM state if CPUUtilizationTooHigh OR DiskReadOpsTooHigh is in ALARM state, and if NetworkOutTooHigh is in OK state. This provides another example of using a composite alarm to prevent noise. This rule ensures that you are not notified with an alarm action on high CPU or disk usage if a known network problem is also occurring.The AlarmRule can specify as many as 100 "children" alarms. The AlarmRule expression can have as many as 500 elements. Elements are child alarms, TRUE or FALSE statements, and parentheses.

CloudWatch.Client.exceptions.LimitExceededFaultput_dashboard(**kwargs)¶Creates a dashboard if it does not already exist, or updates an existing dashboard. If you update a dashboard, the entire contents are replaced with what you specify here.
All dashboards in your account are global, not region-specific.
A simple way to create a dashboard using PutDashboard is to copy an existing dashboard. To copy an existing dashboard using the console, you can load the dashboard and then use the View/edit source command in the Actions menu to display the JSON block for that dashboard. Another way to copy a dashboard is to use GetDashboard , and then use the data returned within DashboardBody as the template for the new dashboard when you call PutDashboard .
When you create a dashboard with PutDashboard , a good practice is to add a text widget at the top of the dashboard with a message that the dashboard was created by script and should not be changed in the console. This message could also point console users to the location of the DashboardBody script or the CloudFormation template used to create the dashboard.

The name for the metric associated with the alarm. For each PutMetricAlarm operation, you must specify either MetricName or a Metrics array.
If you are creating an alarm based on a math expression, you cannot specify this parameter, or any of the Dimensions , Period , Namespace , Statistic , or ExtendedStatistic parameters. Instead, you specify all this information in the Metrics array.
MetricName .MetricName , other than percentile. For percentile statistics, use ExtendedStatistic . When you call PutMetricAlarm and specify a MetricName , you must specify either Statistic or ExtendedStatistic, but not both.MetricName . Specify a value between p0.0 and p100. When you call PutMetricAlarm and specify a MetricName , you must specify either Statistic or ExtendedStatistic, but not both.The dimensions for the metric specified in MetricName .
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
The length, in seconds, used each time the metric specified in MetricName is evaluated. Valid values are 10, 30, and any multiple of 60.
Periodis required for alarms based on static thresholds. If you are creating an alarm based on a metric math expression, you specify the period for each metric within the objects in theMetricsarray.
Be sure to specify 10 or 30 only for metrics that are stored by a PutMetricData call with a StorageResolution of 1. If you specify a period of 10 or 30 for a metric that does not have sub-minute resolution, the alarm still attempts to gather data at the period rate that you specify. In this case, it does not receive data for the attempts that do not correspond to a one-minute data resolution, and the alarm might often lapse into INSUFFICENT_DATA status. Specifying 10 or 30 also sets this alarm as a high-resolution alarm, which has a higher charge than other alarms. For more information about pricing, see Amazon CloudWatch Pricing .
An alarm's total current evaluation period can be no longer than one day, so Period multiplied by EvaluationPeriods cannot be more than 86,400 seconds.
The unit of measure for the statistic. For example, the units for the Amazon EC2 NetworkIn metric are Bytes because NetworkIn tracks the number of bytes that an instance receives on all network interfaces. You can also specify a unit when you create a custom metric. Units help provide conceptual meaning to your data. Metric data points that specify a unit of measure, such as Percent, are aggregated separately.
If you don't specify Unit , CloudWatch retrieves all unit types that have been published for the metric and attempts to evaluate the alarm. Usually, metrics are published with only one unit, so the alarm works as intended.
However, if the metric is published with multiple types of units and you don't specify a unit, the alarm's behavior is not defined and it behaves predictably.
We recommend omitting Unit so that you don't inadvertently specify an incorrect unit that is not published for this metric. Doing so causes the alarm to be stuck in the INSUFFICIENT DATA state.
[REQUIRED]
The number of periods over which data is compared to the specified threshold. If you are setting an alarm that requires that a number of consecutive data points be breaching to trigger the alarm, this value specifies that number. If you are setting an "M out of N" alarm, this value is the N.
An alarm's total current evaluation period can be no longer than one day, so this number multiplied by Period cannot be more than 86,400 seconds.
The value against which the specified statistic is compared.
This parameter is required for alarms based on static thresholds, but should not be used for alarms based on anomaly detection models.
[REQUIRED]
The arithmetic operation to use when comparing the specified statistic and threshold. The specified statistic value is used as the first operand.
The values LessThanLowerOrGreaterThanUpperThreshold , LessThanLowerThreshold , and GreaterThanUpperThreshold are used only for alarms based on anomaly detection models.
Sets how this alarm is to handle missing data points. If TreatMissingData is omitted, the default behavior of missing is used. For more information, see Configuring How CloudWatch Alarms Treats Missing Data .
Valid Values: breaching | notBreaching | ignore | missing
Note
Alarms that evaluate metrics in the AWS/DynamoDB namespace always ignore missing data even if you choose a different option for TreatMissingData . When an AWS/DynamoDB metric has missing data, alarms that evaluate that metric remain in their current state.
Used only for alarms based on percentiles. If you specify ignore , the alarm state does not change during periods with too few data points to be statistically significant. If you specify evaluate or omit this parameter, the alarm is always evaluated and possibly changes state no matter how many data points are available. For more information, see Percentile-Based CloudWatch Alarms and Low Data Samples .
Valid Values: evaluate | ignore
An array of MetricDataQuery structures that enable you to create an alarm based on the result of a metric math expression. For each PutMetricAlarm operation, you must specify either MetricName or a Metrics array.
Each item in the Metrics array either retrieves a metric or performs a math expression.
One item in the Metrics array is the expression that the alarm watches. You designate this expression by setting ReturnData to true for this object in the array. For more information, see MetricDataQuery .
If you use the Metrics parameter, you cannot include the MetricName , Dimensions , Period , Namespace , Statistic , or ExtendedStatistic parameters of PutMetricAlarm in the same operation. Instead, you retrieve the metrics you are using in your math expression as part of the Metrics array.
This structure is used in both GetMetricData and PutMetricAlarm . The supported use of this structure is different for those two operations.
When used in GetMetricData , it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A single GetMetricData call can include up to 500 MetricDataQuery structures.
When used in PutMetricAlarm , it enables you to create an alarm based on a metric math expression. Each MetricDataQuery in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics. A single PutMetricAlarm call can include up to 20 MetricDataQuery structures in the array. The 20 structures can include as many as 10 structures that contain a MetricStat parameter to retrieve a metric, and as many as 10 structures that contain the Expression parameter to perform a math expression. Of those Expression structures, one must have True as the value for ReturnData . The result of this expression is the value the alarm watches.
Any expression used in a PutMetricAlarm operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Some of the parameters of this structure also have different uses whether you are using this structure in a GetMetricData operation or a PutMetricAlarm operation. These differences are explained in the following parameter list.
A short name used to tie this object to the results in the response. This name must be unique within a single call to GetMetricData . If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.
The metric to return, including the metric name, namespace, and dimensions.
The namespace of the metric.
The name of the metric. This is a required field.
The dimensions for the metric.
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
The statistic to return. It can include any CloudWatch statistic or extended statistic.
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, if you omit Unit then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.
This field can contain either a Metrics Insights query, or a metric math expression to be performed on the returned data. For more information about Metrics Insights queries, see Metrics Insights query components and syntax in the Amazon CloudWatch User Guide .
A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
When used in GetMetricData , this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specify False . If you omit this, the default of True is used.
When used in PutMetricAlarm , specify True for the one expression result to use as the alarm. For all other metrics and expressions in the same PutMetricAlarm operation, specify ReturnData as False.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData operation that includes a StorageResolution of 1 second .
The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.
A list of key-value pairs to associate with the alarm. You can associate as many as 50 tags with an alarm.
Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.
If you are using this operation to update an existing alarm, any tags you specify in this parameter are ignored. To change the tags of an existing alarm, use TagResource or UntagResource .
A key-value pair associated with a CloudWatch resource.
A string that you can use to assign a value. The combination of tag keys and values can help you organize and categorize your resources.
The value for the specified tag key.
If this is an alarm based on an anomaly detection model, make this value match the ID of the ANOMALY_DETECTION_BAND function.
For an example of how to use this parameter, see the Anomaly Detection Model Alarm example on this page.
If your alarm uses this parameter, it cannot have Auto Scaling actions.

CloudWatch.Client.exceptions.LimitExceededFaultput_metric_data(**kwargs)¶Publishes metric data points to Amazon CloudWatch. CloudWatch associates the data points with the specified metric. If the specified metric does not exist, CloudWatch creates the metric. When CloudWatch creates a metric, it can take up to fifteen minutes for the metric to appear in calls to ListMetrics .
You can publish either individual data points in the Value field, or arrays of values and the number of times each value occurred during the period by using the Values and Counts fields in the MetricDatum structure. Using the Values and Counts method enables you to publish up to 150 values per metric with one PutMetricData request, and supports retrieving percentile statistics on this data.
Each PutMetricData request is limited to 40 KB in size for HTTP POST requests. You can send a payload compressed by gzip. Each request is also limited to no more than 20 different metrics.
Although the Value parameter accepts numbers of type Double , CloudWatch rejects values that are either too small or too large. Values must be in the range of -2^360 to 2^360. In addition, special values (for example, NaN, +Infinity, -Infinity) are not supported.
You can use up to 10 dimensions per metric to further clarify what data the metric collects. Each dimension consists of a Name and Value pair. For more information about specifying dimensions, see Publishing Metrics in the Amazon CloudWatch User Guide .
You specify the time stamp to be associated with each data point. You can specify time stamps that are as much as two weeks before the current date, and as much as 2 hours after the current day and time.
Data points with time stamps from 24 hours ago or longer can take at least 48 hours to become available for GetMetricData or GetMetricStatistics from the time they are submitted. Data points with time stamps between 3 and 24 hours ago can take as much as 2 hours to become available for for GetMetricData or GetMetricStatistics .
CloudWatch needs raw data points to calculate percentile statistics. If you publish data using a statistic set instead, you can only retrieve percentile statistics for this data if one of the following conditions is true:
SampleCount value of the statistic set is 1 and Min , Max , and Sum are all equal.Min and Max are equal, and Sum is equal to Min multiplied by SampleCount .See also: AWS API Documentation

To avoid conflicts with Amazon Web Services service namespaces, you should not specify a namespace that begins with AWS/
[REQUIRED]
The data for the metric. The array can include no more than 20 metrics per call.
Encapsulates the information sent to either create a metric or add new values to be aggregated into an existing metric.
The name of the metric.
The dimensions associated with the metric.
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
The time the metric data was received, expressed as the number of milliseconds since Jan 1, 1970 00:00:00 UTC.
The value for the metric.
Although the parameter accepts numbers of type Double, CloudWatch rejects values that are either too small or too large. Values must be in the range of -2^360 to 2^360. In addition, special values (for example, NaN, +Infinity, -Infinity) are not supported.
The statistical values for the metric.
The number of samples used for the statistic set.
The sum of values for the sample set.
The minimum value of the sample set.
The maximum value of the sample set.
Array of numbers representing the values for the metric during the period. Each unique value is listed just once in this array, and the corresponding number in the Counts array specifies the number of times that value occurred during the period. You can include up to 150 unique values in each PutMetricData action that specifies a Values array.
Although the Values array accepts numbers of type Double , CloudWatch rejects values that are either too small or too large. Values must be in the range of -2^360 to 2^360. In addition, special values (for example, NaN, +Infinity, -Infinity) are not supported.
Array of numbers that is used along with the Values array. Each number in the Count array is the number of times the corresponding value in the Values array occurred during the period.
If you omit the Counts array, the default of 1 is used as the value for each count. If you include a Counts array, it must include the same amount of values as the Values array.
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, this displays the unit that is used for the metric.
Valid values are 1 and 60. Setting this to 1 specifies this metric as a high-resolution metric, so that CloudWatch stores the metric with sub-minute resolution down to one second. Setting this to 60 specifies this metric as a regular-resolution metric, which CloudWatch stores at 1-minute resolution. Currently, high resolution is available only for custom metrics. For more information about high-resolution metrics, see High-Resolution Metrics in the Amazon CloudWatch User Guide .
This field is optional, if you do not specify it the default of 60 is used.

Metric streams can automatically stream CloudWatch metrics to Amazon Web Services destinations including Amazon S3 and to many third-party solutions.
For more information, see Using Metric Streams .
To create a metric stream, you must be logged on to an account that has the iam:PassRole permission and either the CloudWatchFullAccess policy or the cloudwatch:PutMetricStream permission.
When you create or update a metric stream, you choose one of the following:
ExcludeFilters .IncludeFilters .By default, a metric stream always sends the MAX , MIN , SUM , and SAMPLECOUNT statistics for each metric that is streamed. You can use the StatisticsConfigurations parameter to have the metric stream also send additional statistics in the stream. Streaming additional statistics incurs additional costs. For more information, see Amazon CloudWatch Pricing .
When you use PutMetricStream to create a new metric stream, the stream is created in the running state. If you use it to update an existing stream, the state of the stream is not changed.

When the updated state differs from the previous value, the action configured for the appropriate state is invoked. For example, if your alarm is configured to send an Amazon SNS message when an alarm is triggered, temporarily changing the alarm state to ALARM sends an SNS message.
Metric alarms returns to their actual state quickly, often within seconds. Because the metric alarm state change happens quickly, it is typically only visible in the alarm's History tab in the Amazon CloudWatch console or through DescribeAlarmHistory .
If you use SetAlarmState on a composite alarm, the composite alarm is not guaranteed to return to its actual state. It returns to its actual state only once any of its children alarms change state. It is also reevaluated if you update its configuration.
If an alarm triggers EC2 Auto Scaling policies or application Auto Scaling policies, you must include information in the StateReasonData parameter to enable the policy to take the correct action.

Dimensions (list) --
The dimensions for the metric associated with the alarm.
(dict) --
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
Name (string) --
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
Value (string) --
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.

TreatMissingData (string) --
Sets how this alarm is to handle missing data points. The valid values are breaching , notBreaching , ignore , and missing . For more information, see Configuring how CloudWatch alarms treat missing data .
If this parameter is omitted, the default behavior of missing is used.
EvaluateLowSampleCountPercentile (string) --
Used only for alarms based on percentiles. If ignore , the alarm state does not change during periods with too few data points to be statistically significant. If evaluate or this parameter is not used, the alarm is always evaluated and possibly changes state no matter how many data points are available.
Metrics (list) --
An array of MetricDataQuery structures, used in an alarm based on a metric math expression. Each structure either retrieves a metric or performs a math expression. One item in the Metrics array is the math expression that the alarm watches. This expression by designated by having ReturnData set to true.
(dict) --
This structure is used in both GetMetricData and PutMetricAlarm . The supported use of this structure is different for those two operations.
When used in GetMetricData , it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A single GetMetricData call can include up to 500 MetricDataQuery structures.
When used in PutMetricAlarm , it enables you to create an alarm based on a metric math expression. Each MetricDataQuery in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics. A single PutMetricAlarm call can include up to 20 MetricDataQuery structures in the array. The 20 structures can include as many as 10 structures that contain a MetricStat parameter to retrieve a metric, and as many as 10 structures that contain the Expression parameter to perform a math expression. Of those Expression structures, one must have True as the value for ReturnData . The result of this expression is the value the alarm watches.
Any expression used in a PutMetricAlarm operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Some of the parameters of this structure also have different uses whether you are using this structure in a GetMetricData operation or a PutMetricAlarm operation. These differences are explained in the following parameter list.
Id (string) --
A short name used to tie this object to the results in the response. This name must be unique within a single call to GetMetricData . If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.
MetricStat (dict) --
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.
Metric (dict) --
The metric to return, including the metric name, namespace, and dimensions.
Namespace (string) --
The namespace of the metric.
MetricName (string) --
The name of the metric. This is a required field.
Dimensions (list) --
The dimensions for the metric.
(dict) --
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
Name (string) --
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
Value (string) --
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
Period (integer) --
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
Stat (string) --
The statistic to return. It can include any CloudWatch statistic or extended statistic.
Unit (string) --
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, if you omit Unit then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.
Expression (string) --
This field can contain either a Metrics Insights query, or a metric math expression to be performed on the returned data. For more information about Metrics Insights queries, see Metrics Insights query components and syntax in the Amazon CloudWatch User Guide .
A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.
Label (string) --
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
ReturnData (boolean) --
When used in GetMetricData , this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specify False . If you omit this, the default of True is used.
When used in PutMetricAlarm , specify True for the one expression result to use as the alarm. For all other metrics and expressions in the same PutMetricAlarm operation, specify ReturnData as False.
Period (integer) --
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData operation that includes a StorageResolution of 1 second .
AccountId (string) --
The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.
ThresholdMetricId (string) --
In an alarm based on an anomaly detection model, this is the ID of the ANOMALY_DETECTION_BAND function used as the threshold for the alarm.

[REQUIRED]
The metric queries to be returned. A single GetMetricData call can include as many as 500 MetricDataQuery structures. Each of these structures can specify either a metric to retrieve, a Metrics Insights query, or a math expression to perform on retrieved data.
This structure is used in both GetMetricData and PutMetricAlarm . The supported use of this structure is different for those two operations.
When used in GetMetricData , it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A single GetMetricData call can include up to 500 MetricDataQuery structures.
When used in PutMetricAlarm , it enables you to create an alarm based on a metric math expression. Each MetricDataQuery in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics.

The metric to return, including the metric name, namespace, and dimensions.
The namespace of the metric.
The name of the metric. This is a required field.
The dimensions for the metric.
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.

The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.
[REQUIRED]
The time stamp indicating the earliest data to be returned.
The value specified is inclusive; results include data points with the specified time stamp.
CloudWatch rounds the specified time stamp as follows:
If you set Period to 5, 10, or 30, the start time of your request is rounded down to the nearest time that corresponds to even 5-, 10-, or 30-second divisions of a minute. For example, if you make a query at (HH:mm:ss) 01:05:23 for the previous 10-second period, the start time of your request is rounded down and you receive data from 01:05:10 to 01:05:20. If you make a query at 15:07:17 for the previous 5 minutes of data, using a period of 5 seconds, you receive data timestamped between 15:02:15 and 15:07:15.
For better performance, specify StartTime and EndTime values that align with the value of the metric's Period and sync up with the beginning and end of an hour. For example, if the Period of a metric is 5 minutes, specifying 12:05 or 12:30 as StartTime can get a faster response from CloudWatch than setting 12:07 or 12:29 as the StartTime .
[REQUIRED]
The time stamp indicating the latest data to be returned.
The value specified is exclusive; results include data points up to the specified time stamp.
For better performance, specify StartTime and EndTime values that align with the value of the metric's Period and sync up with the beginning and end of an hour. For example, if the Period of a metric is 5 minutes, specifying 12:05 or 12:30 as EndTime can get a faster response from CloudWatch than setting 12:07 or 12:29 as the EndTime .
TimestampDescending returns the newest data first and paginates when the MaxDatapoints limit is reached. TimestampAscending returns the oldest data first and paginates when the MaxDatapoints limit is reached.This structure includes the Timezone parameter, which you can use to specify your time zone so that the labels of returned data display the correct time for your time zone.
The time zone to use for metric data return in this operation. The format is + or - followed by four digits. The first two digits indicate the number of hours ahead or behind of UTC, and the final two digits are the number of minutes. For example, +0130 indicates a time zone that is 1 hour and 30 minutes ahead of UTC. The default is +0000.
A dictionary that provides parameters to control pagination.
The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.
The size of each page.
A token to specify where to start paginating. This is the NextToken from a previous response.

Metrics (list) --
The metrics that match your request.
(dict) --
Represents a specific metric.
Namespace (string) --
The namespace of the metric.
MetricName (string) --
The name of the metric. This is a required field.
Dimensions (list) --
The dimensions for the metric.
(dict) --
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
Name (string) --
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
Value (string) --
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.

These are the resource's available collections:
Sub-resources
Sub-resources are methods that create a new instance of a child resource. This resource's identifiers get passed along to the child. For more information about sub-resources refer to the Resources Introduction Guide.
Alarm(name)¶Creates a Alarm resource.:
alarm = cloudwatch.Alarm('name')
CloudWatch.AlarmMetric(namespace, name)¶Creates a Metric resource.:
metric = cloudwatch.Metric('namespace','name')

Collections
Collections provide an interface to iterate over and manipulate groups of resources. For more information about collections refer to the Resources Introduction Guide.
alarms¶A collection of Alarm resources.A Alarm Collection will include all resources by default, and extreme caution should be taken when performing actions on all resources.
all()¶Creates an iterable of all Alarm resources in the collection.

Request Syntax
alarm_iterator = cloudwatch.alarms.all()
cloudwatch.Alarm)delete()¶Deletes the specified alarms. You can delete up to 100 alarms in one operation. However, this total can include no more than one composite alarm. For example, you could delete 99 metric alarms and one composite alarms with one operation, but you can't delete two composite alarms with one operation.
In the event of an error, no alarms are deleted.
Note
It is possible to create a loop or cycle of composite alarms, where composite alarm A depends on composite alarm B, and composite alarm B also depends on composite alarm A. In this scenario, you can't delete any composite alarm that is part of the cycle because there is always still a composite alarm that depends on that alarm that you want to delete.
To get out of such a situation, you must break the cycle by changing the rule of one of the composite alarms in the cycle to remove a dependency that creates the cycle. The simplest change to make to break a cycle is to change the AlarmRule of one of the alarms to False .
Additionally, the evaluation of composite alarms stops if CloudWatch detects a cycle in the evaluation path.

Attributes
Attributes provide access to the properties of a resource. Attributes are lazy-loaded the first time one is accessed via the load() method.
For more information about attributes refer to the Resources Introduction Guide.
actions_enabled¶(boolean) --
Indicates whether actions should be executed during any changes to the alarm state.
alarm_actions¶(list) --
The actions to execute when this alarm transitions to the ALARM state from any other state. Each action is specified as an Amazon Resource Name (ARN).
alarm_arn¶(string) --
The Amazon Resource Name (ARN) of the alarm.
alarm_configuration_updated_timestamp¶(datetime) --
The time stamp of the last update to the alarm configuration.
alarm_description¶(string) --
The description of the alarm.
alarm_name¶(string) --
The name of the alarm.
comparison_operator¶(string) --
The arithmetic operation to use when comparing the specified statistic and threshold. The specified statistic value is used as the first operand.
datapoints_to_alarm¶(integer) --
The number of data points that must be breaching to trigger the alarm.
dimensions¶(list) --
The dimensions for the metric associated with the alarm.
(dict) --
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
Name (string) --
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
Value (string) --
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
evaluate_low_sample_count_percentile¶(string) --
Used only for alarms based on percentiles. If ignore , the alarm state does not change during periods with too few data points to be statistically significant. If evaluate or this parameter is not used, the alarm is always evaluated and possibly changes state no matter how many data points are available.
evaluation_periods¶(integer) --
The number of periods over which data is compared to the specified threshold.
extended_statistic¶(string) --
The percentile statistic for the metric associated with the alarm. Specify a value between p0.0 and p100.
insufficient_data_actions¶(list) --
The actions to execute when this alarm transitions to the INSUFFICIENT_DATA state from any other state. Each action is specified as an Amazon Resource Name (ARN).
metric_name¶(string) --
The name of the metric associated with the alarm, if this is an alarm based on a single metric.
metrics¶(list) --
An array of MetricDataQuery structures, used in an alarm based on a metric math expression. Each structure either retrieves a metric or performs a math expression. One item in the Metrics array is the math expression that the alarm watches. This expression by designated by having ReturnData set to true.
(dict) --
This structure is used in both GetMetricData and PutMetricAlarm . The supported use of this structure is different for those two operations.
When used in GetMetricData , it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A single GetMetricData call can include up to 500 MetricDataQuery structures.
When used in PutMetricAlarm , it enables you to create an alarm based on a metric math expression. Each MetricDataQuery in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics. A single PutMetricAlarm call can include up to 20 MetricDataQuery structures in the array. The 20 structures can include as many as 10 structures that contain a MetricStat parameter to retrieve a metric, and as many as 10 structures that contain the Expression parameter to perform a math expression. Of those Expression structures, one must have True as the value for ReturnData . The result of this expression is the value the alarm watches.
Any expression used in a PutMetricAlarm operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Some of the parameters of this structure also have different uses whether you are using this structure in a GetMetricData operation or a PutMetricAlarm operation. These differences are explained in the following parameter list.
Id (string) --
A short name used to tie this object to the results in the response. This name must be unique within a single call to GetMetricData . If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.
MetricStat (dict) --
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.
Metric (dict) --
The metric to return, including the metric name, namespace, and dimensions.
Namespace (string) --
The namespace of the metric.
MetricName (string) --
The name of the metric. This is a required field.
Dimensions (list) --
The dimensions for the metric.
(dict) --
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
Name (string) --
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
Value (string) --
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
Period (integer) --
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
Stat (string) --
The statistic to return. It can include any CloudWatch statistic or extended statistic.
Unit (string) --
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, if you omit Unit then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.
Expression (string) --
This field can contain either a Metrics Insights query, or a metric math expression to be performed on the returned data. For more information about Metrics Insights queries, see Metrics Insights query components and syntax in the Amazon CloudWatch User Guide .
A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.
Label (string) --
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
ReturnData (boolean) --
When used in GetMetricData , this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specify False . If you omit this, the default of True is used.
When used in PutMetricAlarm , specify True for the one expression result to use as the alarm. For all other metrics and expressions in the same PutMetricAlarm operation, specify ReturnData as False.
Period (integer) --
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData operation that includes a StorageResolution of 1 second .
AccountId (string) --
The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.
namespace¶(string) --
The namespace of the metric associated with the alarm.
ok_actions¶(list) --
The actions to execute when this alarm transitions to the OK state from any other state. Each action is specified as an Amazon Resource Name (ARN).
period¶(integer) --
The period, in seconds, over which the statistic is applied.
state_reason¶(string) --
An explanation for the alarm state, in text format.
state_reason_data¶(string) --
An explanation for the alarm state, in JSON format.
state_updated_timestamp¶(datetime) --
The time stamp of the last update to the alarm state.
state_value¶(string) --
The state value for the alarm.
statistic¶(string) --
The statistic for the metric associated with the alarm, other than percentile. For percentile statistics, use ExtendedStatistic .
threshold¶(float) --
The value to compare with the specified statistic.
threshold_metric_id¶(string) --
In an alarm based on an anomaly detection model, this is the ID of the ANOMALY_DETECTION_BAND function used as the threshold for the alarm.
treat_missing_data¶(string) --
Sets how this alarm is to handle missing data points. The valid values are breaching , notBreaching , ignore , and missing . For more information, see Configuring how CloudWatch alarms treat missing data .
If this parameter is omitted, the default behavior of missing is used.
unit¶(string) --
The unit of the metric associated with the alarm.
References
References are related resource instances that have a belongs-to relationship. For more information about references refer to the Resources Introduction Guide.
metric¶(Metric) The related metric if set, otherwise None.
Actions
Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.
delete()¶Deletes the specified alarms. You can delete up to 100 alarms in one operation. However, this total can include no more than one composite alarm. For example, you could delete 99 metric alarms and one composite alarms with one operation, but you can't delete two composite alarms with one operation.
In the event of an error, no alarms are deleted.
Note
It is possible to create a loop or cycle of composite alarms, where composite alarm A depends on composite alarm B, and composite alarm B also depends on composite alarm A. In this scenario, you can't delete any composite alarm that is part of the cycle because there is always still a composite alarm that depends on that alarm that you want to delete.
To get out of such a situation, you must break the cycle by changing the rule of one of the composite alarms in the cycle to remove a dependency that creates the cycle. The simplest change to make to break a cycle is to change the AlarmRule of one of the alarms to False .
Additionally, the evaluation of composite alarms stops if CloudWatch detects a cycle in the evaluation path.

response = alarm.delete()
describe_history(**kwargs)¶Retrieves the history for the specified alarm. You can filter the results by date range or item type. If an alarm name is not specified, the histories for either all metric alarms or all composite alarms are returned.
CloudWatch retains the history of an alarm even if you delete the alarm.
To use this operation and return information about a composite alarm, you must be signed on with the cloudwatch:DescribeAlarmHistory permission that is scoped to * . You can't return information about composite alarms if your cloudwatch:DescribeAlarmHistory permission has a narrower scope.

Request Syntax
alarm.reload()
set_state(**kwargs)¶Temporarily sets the state of an alarm for testing purposes. When the updated state differs from the previous value, the action configured for the appropriate state is invoked. For example, if your alarm is configured to send an Amazon SNS message when an alarm is triggered, temporarily changing the alarm state to ALARM sends an SNS message.
Metric alarms returns to their actual state quickly, often within seconds. Because the metric alarm state change happens quickly, it is typically only visible in the alarm's History tab in the Amazon CloudWatch console or through DescribeAlarmHistory .
If you use SetAlarmState on a composite alarm, the composite alarm is not guaranteed to return to its actual state. It returns to its actual state only once any of its children alarms change state. It is also reevaluated if you update its configuration.
If an alarm triggers EC2 Auto Scaling policies or application Auto Scaling policies, you must include information in the StateReasonData parameter to enable the policy to take the correct action.

CloudWatch.Metric(namespace, name)¶A resource representing an Amazon CloudWatch Metric:
import boto3
cloudwatch = boto3.resource('cloudwatch')
metric = cloudwatch.Metric('namespace','name')
These are the resource's available identifiers:
These are the resource's available attributes:
These are the resource's available actions:
These are the resource's available collections:
Identifiers
Identifiers are properties of a resource that are set upon instantiation of the resource. For more information about identifiers refer to the Resources Introduction Guide.
namespace¶(string) The Metric's namespace identifier. This must be set.
name¶(string) The Metric's name identifier. This must be set.
Attributes
Attributes provide access to the properties of a resource. Attributes are lazy-loaded the first time one is accessed via the load() method.
For more information about attributes refer to the Resources Introduction Guide.
dimensions¶(list) --
The dimensions for the metric.
(dict) --
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
Name (string) --
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
Value (string) --
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
metric_name¶(string) --
The name of the metric. This is a required field.
Actions
Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.
get_available_subresources()¶Returns a list of all the available sub-resources for this Resource.
get_statistics(**kwargs)¶Gets statistics for the specified metric.
The maximum number of data points returned from a single call is 1,440. If you request more than 1,440 data points, CloudWatch returns an error. To reduce the number of data points, you can narrow the specified time range and make multiple requests across adjacent time ranges, or you can increase the specified period. Data points are not returned in chronological order.
CloudWatch aggregates data points based on the length of the period that you specify. For example, if you request statistics with a one-hour period, CloudWatch aggregates all data points with time stamps that fall within each one-hour period. Therefore, the number of values aggregated by CloudWatch is larger than the number of data points returned.
CloudWatch needs raw data points to calculate percentile statistics. If you publish data using a statistic set instead, you can only retrieve percentile statistics for this data if one of the following conditions is true:
Percentile statistics are not available for metrics when any of the metric values are negative numbers.
Amazon CloudWatch retains metric data as follows:
StorageResolution of 1.Data points that are initially published with a shorter period are aggregated together for long-term storage. For example, if you collect data using a period of 1 minute, the data remains available for 15 days with 1-minute resolution. After 15 days, this data is still available, but is aggregated and retrievable only with a resolution of 5 minutes. After 63 days, the data is further aggregated and is available with a resolution of 1 hour.
CloudWatch started retaining 5-minute and 1-hour metric data as of July 9, 2016.
For information about metrics and dimensions supported by Amazon Web Services services, see the Amazon CloudWatch Metrics and Dimensions Reference in the Amazon CloudWatch User Guide .

The dimensions. If the metric contains multiple dimensions, you must include a value for each dimension. CloudWatch treats each unique combination of dimensions as a separate metric. If a specific combination of dimensions was not published, you can't retrieve statistics for it. You must specify the same dimensions that were used when the metrics were created. For an example, see Dimension Combinations in the Amazon CloudWatch User Guide . For more information about specifying dimensions, see Publishing Metrics in the Amazon CloudWatch User Guide .
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
[REQUIRED]
The time stamp that determines the first data point to return. Start times are evaluated relative to the time that CloudWatch receives the request.
The value specified is inclusive; results include data points with the specified time stamp. In a raw HTTP query, the time stamp must be in ISO 8601 UTC format (for example, 2016-10-03T23:00:00Z).
CloudWatch rounds the specified time stamp as follows:
If you set Period to 5, 10, or 30, the start time of your request is rounded down to the nearest time that corresponds to even 5-, 10-, or 30-second divisions of a minute. For example, if you make a query at (HH:mm:ss) 01:05:23 for the previous 10-second period, the start time of your request is rounded down and you receive data from 01:05:10 to 01:05:20. If you make a query at 15:07:17 for the previous 5 minutes of data, using a period of 5 seconds, you receive data timestamped between 15:02:15 and 15:07:15.
[REQUIRED]
The time stamp that determines the last data point to return.
The value specified is exclusive; results include data points up to the specified time stamp. In a raw HTTP query, the time stamp must be in ISO 8601 UTC format (for example, 2016-10-10T23:00:00Z).
[REQUIRED]
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
The metric statistics, other than percentile. For percentile statistics, use ExtendedStatistics . When calling GetMetricStatistics , you must specify either Statistics or ExtendedStatistics , but not both.
The percentile statistics. Specify values between p0.0 and p100. When calling GetMetricStatistics , you must specify either Statistics or ExtendedStatistics , but not both. Percentile statistics are not available for metrics when any of the metric values are negative numbers.
Unit , all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.dict

metric.load()
put_alarm(**kwargs)¶Creates or updates an alarm and associates it with the specified metric, metric math expression, or anomaly detection model.
Alarms based on anomaly detection models cannot have Auto Scaling actions.
When this operation creates an alarm, the alarm state is immediately set to INSUFFICIENT_DATA . The alarm is then evaluated and its state is set appropriately. Any actions associated with the new state are then executed.
When you update an existing alarm, its state is left unchanged, but the update completely overwrites the previous configuration of the alarm.
If you are an IAM user, you must have Amazon EC2 permissions for some alarm operations:
iam:CreateServiceLinkedRole for all alarms with EC2 actionsiam:CreateServiceLinkedRole to create an alarm with Systems Manager OpsItem actions.The first time you create an alarm in the Amazon Web Services Management Console, the CLI, or by using the PutMetricAlarm API, CloudWatch creates the necessary service-linked role for you. The service-linked roles are called AWSServiceRoleForCloudWatchEvents and AWSServiceRoleForCloudWatchAlarms_ActionSSM . For more information, see Amazon Web Services service-linked role .
Cross-account alarms
You can set an alarm on metrics in the current account, or in another account. To create a cross-account alarm that watches a metric in a different account, you must have completed the following pre-requisites:

MetricName , other than percentile. For percentile statistics, use ExtendedStatistic . When you call PutMetricAlarm and specify a MetricName , you must specify either Statistic or ExtendedStatistic, but not both.MetricName . Specify a value between p0.0 and p100. When you call PutMetricAlarm and specify a MetricName , you must specify either Statistic or ExtendedStatistic, but not both.The dimensions for the metric specified in MetricName .
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
The length, in seconds, used each time the metric specified in MetricName is evaluated. Valid values are 10, 30, and any multiple of 60.
Periodis required for alarms based on static thresholds. If you are creating an alarm based on a metric math expression, you specify the period for each metric within the objects in theMetricsarray.
Be sure to specify 10 or 30 only for metrics that are stored by a PutMetricData call with a StorageResolution of 1. If you specify a period of 10 or 30 for a metric that does not have sub-minute resolution, the alarm still attempts to gather data at the period rate that you specify. In this case, it does not receive data for the attempts that do not correspond to a one-minute data resolution, and the alarm might often lapse into INSUFFICENT_DATA status. Specifying 10 or 30 also sets this alarm as a high-resolution alarm, which has a higher charge than other alarms. For more information about pricing, see Amazon CloudWatch Pricing .
An alarm's total current evaluation period can be no longer than one day, so Period multiplied by EvaluationPeriods cannot be more than 86,400 seconds.
The unit of measure for the statistic. For example, the units for the Amazon EC2 NetworkIn metric are Bytes because NetworkIn tracks the number of bytes that an instance receives on all network interfaces. You can also specify a unit when you create a custom metric. Units help provide conceptual meaning to your data. Metric data points that specify a unit of measure, such as Percent, are aggregated separately.
If you don't specify Unit , CloudWatch retrieves all unit types that have been published for the metric and attempts to evaluate the alarm. Usually, metrics are published with only one unit, so the alarm works as intended.
However, if the metric is published with multiple types of units and you don't specify a unit, the alarm's behavior is not defined and it behaves predictably.
We recommend omitting Unit so that you don't inadvertently specify an incorrect unit that is not published for this metric. Doing so causes the alarm to be stuck in the INSUFFICIENT DATA state.
[REQUIRED]
The number of periods over which data is compared to the specified threshold. If you are setting an alarm that requires that a number of consecutive data points be breaching to trigger the alarm, this value specifies that number. If you are setting an "M out of N" alarm, this value is the N.
An alarm's total current evaluation period can be no longer than one day, so this number multiplied by Period cannot be more than 86,400 seconds.
The value against which the specified statistic is compared.
This parameter is required for alarms based on static thresholds, but should not be used for alarms based on anomaly detection models.
[REQUIRED]
The arithmetic operation to use when comparing the specified statistic and threshold. The specified statistic value is used as the first operand.
The values LessThanLowerOrGreaterThanUpperThreshold , LessThanLowerThreshold , and GreaterThanUpperThreshold are used only for alarms based on anomaly detection models.
Sets how this alarm is to handle missing data points. If TreatMissingData is omitted, the default behavior of missing is used. For more information, see Configuring How CloudWatch Alarms Treats Missing Data .
Valid Values: breaching | notBreaching | ignore | missing
Note
Alarms that evaluate metrics in the AWS/DynamoDB namespace always ignore missing data even if you choose a different option for TreatMissingData . When an AWS/DynamoDB metric has missing data, alarms that evaluate that metric remain in their current state.
Used only for alarms based on percentiles. If you specify ignore , the alarm state does not change during periods with too few data points to be statistically significant. If you specify evaluate or omit this parameter, the alarm is always evaluated and possibly changes state no matter how many data points are available. For more information, see Percentile-Based CloudWatch Alarms and Low Data Samples .
Valid Values: evaluate | ignore
An array of MetricDataQuery structures that enable you to create an alarm based on the result of a metric math expression. For each PutMetricAlarm operation, you must specify either MetricName or a Metrics array.
Each item in the Metrics array either retrieves a metric or performs a math expression.
One item in the Metrics array is the expression that the alarm watches. You designate this expression by setting ReturnData to true for this object in the array. For more information, see MetricDataQuery .
If you use the Metrics parameter, you cannot include the MetricName , Dimensions , Period , Namespace , Statistic , or ExtendedStatistic parameters of PutMetricAlarm in the same operation. Instead, you retrieve the metrics you are using in your math expression as part of the Metrics array.
This structure is used in both GetMetricData and PutMetricAlarm . The supported use of this structure is different for those two operations.
When used in GetMetricData , it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A single GetMetricData call can include up to 500 MetricDataQuery structures.
When used in PutMetricAlarm , it enables you to create an alarm based on a metric math expression. Each MetricDataQuery in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics. A single PutMetricAlarm call can include up to 20 MetricDataQuery structures in the array. The 20 structures can include as many as 10 structures that contain a MetricStat parameter to retrieve a metric, and as many as 10 structures that contain the Expression parameter to perform a math expression. Of those Expression structures, one must have True as the value for ReturnData . The result of this expression is the value the alarm watches.
Any expression used in a PutMetricAlarm operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Some of the parameters of this structure also have different uses whether you are using this structure in a GetMetricData operation or a PutMetricAlarm operation. These differences are explained in the following parameter list.
A short name used to tie this object to the results in the response. This name must be unique within a single call to GetMetricData . If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either Expression or MetricStat but not both.
The metric to return, including the metric name, namespace, and dimensions.
The namespace of the metric.
The name of the metric. This is a required field.
The dimensions for the metric.
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData call that includes a StorageResolution of 1 second.
If the StartTime parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
The statistic to return. It can include any CloudWatch statistic or extended statistic.
When you are using a Put operation, this defines what unit you want to use when storing the metric.
In a Get operation, if you omit Unit then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.
This field can contain either a Metrics Insights query, or a metric math expression to be performed on the returned data. For more information about Metrics Insights queries, see Metrics Insights query components and syntax in the Amazon CloudWatch User Guide .
A math expression can use the Id of the other metrics or queries to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .
Within each MetricDataQuery object, you must specify either Expression or MetricStat but not both.
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
When used in GetMetricData , this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specify False . If you omit this, the default of True is used.
When used in PutMetricAlarm , specify True for the one expression result to use as the alarm. For all other metrics and expressions in the same PutMetricAlarm operation, specify ReturnData as False.
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a PutMetricData operation that includes a StorageResolution of 1 second .
The ID of the account where the metrics are located, if this is a cross-account alarm.
Use this field only for PutMetricAlarm operations. It is not used in GetMetricData operations.
A list of key-value pairs to associate with the alarm. You can associate as many as 50 tags with an alarm.
Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.
If you are using this operation to update an existing alarm, any tags you specify in this parameter are ignored. To change the tags of an existing alarm, use TagResource or UntagResource .
A key-value pair associated with a CloudWatch resource.
A string that you can use to assign a value. The combination of tag keys and values can help you organize and categorize your resources.
The value for the specified tag key.
If this is an alarm based on an anomaly detection model, make this value match the ID of the ANOMALY_DETECTION_BAND function.
For an example of how to use this parameter, see the Anomaly Detection Model Alarm example on this page.
If your alarm uses this parameter, it cannot have Auto Scaling actions.
cloudwatch.Alarm
Alarm resource
put_data()¶Publishes metric data points to Amazon CloudWatch. CloudWatch associates the data points with the specified metric. If the specified metric does not exist, CloudWatch creates the metric. When CloudWatch creates a metric, it can take up to fifteen minutes for the metric to appear in calls to ListMetrics .
You can publish either individual data points in the Value field, or arrays of values and the number of times each value occurred during the period by using the Values and Counts fields in the MetricDatum structure. Using the Values and Counts method enables you to publish up to 150 values per metric with one PutMetricData request, and supports retrieving percentile statistics on this data.
Each PutMetricData request is limited to 40 KB in size for HTTP POST requests. You can send a payload compressed by gzip. Each request is also limited to no more than 20 different metrics.
Although the Value parameter accepts numbers of type Double , CloudWatch rejects values that are either too small or too large. Values must be in the range of -2^360 to 2^360. In addition, special values (for example, NaN, +Infinity, -Infinity) are not supported.
You can use up to 10 dimensions per metric to further clarify what data the metric collects. Each dimension consists of a Name and Value pair. For more information about specifying dimensions, see Publishing Metrics in the Amazon CloudWatch User Guide .
You specify the time stamp to be associated with each data point. You can specify time stamps that are as much as two weeks before the current date, and as much as 2 hours after the current day and time.
Data points with time stamps from 24 hours ago or longer can take at least 48 hours to become available for GetMetricData or GetMetricStatistics from the time they are submitted. Data points with time stamps between 3 and 24 hours ago can take as much as 2 hours to become available for for GetMetricData or GetMetricStatistics .
CloudWatch needs raw data points to calculate percentile statistics. If you publish data using a statistic set instead, you can only retrieve percentile statistics for this data if one of the following conditions is true:
SampleCount value of the statistic set is 1 and Min , Max , and Sum are all equal.Min and Max are equal, and Sum is equal to Min multiplied by SampleCount .See also: AWS API Documentation

response = metric.put_data()
reload()¶Calls CloudWatch.Client.list_metrics() to update the attributes of the Metric resource. Note that the load and reload methods are the same method and can be used interchangeably.

metric.reload()
Collections
Collections provide an interface to iterate over and manipulate groups of resources. For more information about collections refer to the Resources Introduction Guide.
alarms¶A collection of Alarm resources.A Alarm Collection will include all resources by default, and extreme caution should be taken when performing actions on all resources.
all()¶Creates an iterable of all Alarm resources in the collection.
See also: AWS API Documentation
Request Syntax
alarm_iterator = metric.alarms.all()
cloudwatch.Alarm)delete()¶Deletes the specified alarms. You can delete up to 100 alarms in one operation. However, this total can include no more than one composite alarm. For example, you could delete 99 metric alarms and one composite alarms with one operation, but you can't delete two composite alarms with one operation.
In the event of an error, no alarms are deleted.
Note
It is possible to create a loop or cycle of composite alarms, where composite alarm A depends on composite alarm B, and composite alarm B also depends on composite alarm A. In this scenario, you can't delete any composite alarm that is part of the cycle because there is always still a composite alarm that depends on that alarm that you want to delete.
To get out of such a situation, you must break the cycle by changing the rule of one of the composite alarms in the cycle to remove a dependency that creates the cycle. The simplest change to make to break a cycle is to change the AlarmRule of one of the alarms to False .
Additionally, the evaluation of composite alarms stops if CloudWatch detects a cycle in the evaluation path.

response = metric.alarms.delete()
disable_actions()¶Disables the actions for the specified alarms. When an alarm's actions are disabled, the alarm actions do not execute when the alarm state changes.
See also: AWS API Documentation
Request Syntax
response = metric.alarms.disable_actions()
enable_actions()¶Enables the actions for the specified alarms.
See also: AWS API Documentation
Request Syntax
response = metric.alarms.enable_actions()
filter(**kwargs)¶Creates an iterable of all Alarm resources in the collection filtered by kwargs passed to method. A Alarm collection will include all resources by default if no filters are provided, and extreme caution should be taken when performing actions on all resources.

Request Syntax
alarm_iterator = metric.alarms.filter(
Statistic='SampleCount'|'Average'|'Sum'|'Minimum'|'Maximum',
ExtendedStatistic='string',

)
ExtendedStatistics .The dimensions associated with the metric. If the metric has any associated dimensions, you must specify them in order for the call to succeed.
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish InstanceId as a dimension name, and the actual instance ID as the value for that dimension.
You can assign up to 10 dimensions to a metric.
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (: ).
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character.
list(cloudwatch.Alarm)
A list of Alarm resources
limit(**kwargs)¶Creates an iterable up to a specified amount of Alarm resources in the collection.
