get_reservation_utilization#

CostExplorer.Client.get_reservation_utilization(**kwargs)#

Retrieves the reservation utilization for your account. Management account in an organization have access to member accounts. You can filter data by dimensions in a time period. You can use GetDimensionValues to determine the possible dimension values. Currently, you can group only by SUBSCRIPTION_ID.

Parameters:

TimePeriod (dict) –
[REQUIRED]

Sets the start and end dates for retrieving Reserved Instance (RI) utilization. The start date is inclusive, but the end date is exclusive. For example, if start is 2017-01-01 and end is 2017-05-01, then the cost and usage data is retrieved from 2017-01-01 up to and including 2017-04-30 but not including 2017-05-01.
- Start (string) – [REQUIRED]
  
  The beginning of the time period. The start date is inclusive. For example, if start is 2017-01-01, Amazon Web Services retrieves cost and usage data starting at 2017-01-01 up to the end date. The start date must be equal to or no later than the current date to avoid a validation error.
- End (string) – [REQUIRED]
  
  The end of the time period. The end date is exclusive. For example, if end is 2017-05-01, Amazon Web Services retrieves cost and usage data from the start date up to, but not including, 2017-05-01.
GroupBy (list) –
Groups only by SUBSCRIPTION_ID. Metadata is included.
- (dict) –
  
  Represents a group when you specify a group by criteria or in the response to a query with a specific grouping.
  - Type (string) –
    
    The string that represents the type of group.
  - Key (string) –
    
    The string that represents a key for a specified group.
Granularity (string) –
If GroupBy is set, Granularity can’t be set. If Granularity isn’t set, the response object doesn’t include Granularity, either MONTHLY or DAILY. If both GroupBy and Granularity aren’t set, GetReservationUtilization defaults to DAILY.

The GetReservationUtilization operation supports only DAILY and MONTHLY granularities.
Filter (dict) –
Filters utilization data by dimensions. You can filter by the following dimensions:
- AZ
- CACHE_ENGINE
- DEPLOYMENT_OPTION
- INSTANCE_TYPE
- LINKED_ACCOUNT
- OPERATING_SYSTEM
- PLATFORM
- REGION
- SERVICE
Note
If not specified, the SERVICE filter defaults to Amazon Elastic Compute Cloud - Compute. Supported values for SERVICE are Amazon Elastic Compute Cloud - Compute, Amazon Relational Database Service, Amazon ElastiCache, Amazon Redshift, and Amazon Elasticsearch Service. The value for the SERVICE filter should not exceed “1”.
- SCOPE
- TENANCY
GetReservationUtilization uses the same Expression object as the other operations, but only AND is supported among each dimension, and nesting is supported up to only one level deep. If there are multiple values for a dimension, they are OR’d together.
- Or (list) –
  
  Return results that match either Dimension object.
  - (dict) –
    
    Use Expression to filter in various Cost Explorer APIs.
    
    Not all Expression types are supported in each API. Refer to the documentation for each specific API to see what is supported.
    
    There are two patterns:
    - Simple dimension values.
      - There are three types of simple dimension values: CostCategories, Tags, and Dimensions.
        
        Specify the CostCategories field to define a filter that acts on Cost Categories.
        
        Specify the Tags field to define a filter that acts on Cost Allocation Tags.
        
        Specify the Dimensions field to define a filter that acts on the DimensionValues.
      - For each filter type, you can set the dimension name and values for the filters that you plan to use.
        
        For example, you can filter for REGION==us-east-1 OR REGION==us-west-1. For GetRightsizingRecommendation, the Region is a full name (for example, REGION==US East (N. Virginia).
        
        The corresponding Expression for this example is as follows: { "Dimensions": { "Key": "REGION", "Values": [ "us-east-1", "us-west-1" ] } }
        
        As shown in the previous example, lists of dimension values are combined with OR when applying the filter.
      - You can also set different match options to further control how the filter behaves. Not all APIs support match options. Refer to the documentation for each specific API to see what is supported.
        
        For example, you can filter for linked account names that start with “a”.
        
        The corresponding Expression for this example is as follows: { "Dimensions": { "Key": "LINKED_ACCOUNT_NAME", "MatchOptions": [ "STARTS_WITH" ], "Values": [ "a" ] } }
    - Compound Expression types with logical operations.
      - You can use multiple Expression types and the logical operators AND/OR/NOT to create a list of one or more Expression objects. By doing this, you can filter by more advanced options.
      - For example, you can filter by ((REGION == us-east-1 OR REGION == us-west-1) OR (TAG.Type == Type1)) AND (USAGE_TYPE != DataTransfer).
      - The corresponding Expression for this example is as follows: { "And": [ {"Or": [ {"Dimensions": { "Key": "REGION", "Values": [ "us-east-1", "us-west-1" ] }}, {"Tags": { "Key": "TagName", "Values": ["Value1"] } } ]}, {"Not": {"Dimensions": { "Key": "USAGE_TYPE", "Values": ["DataTransfer"] }}} ] }
    Note
    Because each Expression can have only one operator, the service returns an error if more than one is specified. The following example shows an Expression object that creates an error: { "And": [ ... ], "Dimensions": { "Key": "USAGE_TYPE", "Values": [ "DataTransfer" ] } }
    
    The following is an example of the corresponding error message: "Expression has more than one roots. Only one root operator is allowed for each expression: And, Or, Not, Dimensions, Tags, CostCategories"
    
    Note
    For the GetRightsizingRecommendation action, a combination of OR and NOT isn’t supported. OR isn’t supported between different dimensions, or dimensions and tags. NOT operators aren’t supported. Dimensions are also limited to LINKED_ACCOUNT, REGION, or RIGHTSIZING_TYPE.
    
    For the GetReservationPurchaseRecommendation action, only NOT is supported. AND and OR aren’t supported. Dimensions are limited to LINKED_ACCOUNT.
- And (list) –
  
  Return results that match both Dimension objects.
  - (dict) –
    
    Use Expression to filter in various Cost Explorer APIs.
    
    Not all Expression types are supported in each API. Refer to the documentation for each specific API to see what is supported.

        Specify the Tags field to define a filter that acts on Cost Allocation Tags.
        
        Specify the Dimensions field to define a filter that acts on the DimensionValues.
      - For each filter type, you can set the dimension name and values for the filters that you plan to use.
        
        For example, you can filter for REGION==us-east-1 OR REGION==us-west-1. For GetRightsizingRecommendation, the Region is a full name (for example, REGION==US East (N. Virginia).
