Response Structure
A structure that contains the full information about the canary.
The unique ID of this canary.
The name of the canary.
This structure contains information about the canary's Lambda handler and where its code is stored by CloudWatch Synthetics.
The ARN of the Lambda layer where Synthetics stores the canary script code.
The entry point to use for the source code when running the canary.
The ARN of the IAM role used to run the canary. This role must include lambda.amazonaws.com as a principal in the trust policy.
A structure that contains information about how often the canary is to run, and when these runs are to stop.
A rate expression or a cron expression that defines how often the canary is to run.
For a rate expression, The syntax is rate(number unit) . unit can be minute , minutes , or hour .
For example, rate(1 minute) runs the canary once a minute, rate(10 minutes) runs it once every 10 minutes, and rate(1 hour) runs it once every hour. You can specify a frequency between rate(1 minute) and rate(1 hour) .
Specifying rate(0 minute) or rate(0 hour) is a special value that causes the canary to run only once when it is started.
Use cron(expression) to specify a cron expression. For information about the syntax for cron expressions, see Scheduling canary runs using cron.
How long, in seconds, for the canary to continue making regular runs after it was created. The runs are performed according to the schedule in the Expression value.
A structure that contains information about a canary run.
How long the canary is allowed to run before it must stop.
The maximum amount of memory available to the canary while it is running, in MB. This value must be a multiple of 64.
Displays whether this canary run used active X-Ray tracing.
The number of days to retain data about successful runs of this canary.
The number of days to retain data about failed runs of this canary.
A structure that contains information about the canary's status.
The current state of the canary.
If the canary has insufficient permissions to run, this field provides more details.
If the canary cannot run or has failed, this field displays the reason.
A structure that contains information about when the canary was created, modified, and most recently run.
The date and time the canary was created.
The date and time the canary was most recently modified.
The date and time that the canary's most recent run started.
The date and time that the canary's most recent run ended.
The location in Amazon S3 where Synthetics stores artifacts from the runs of this canary. Artifacts include the log file, screenshots, and HAR files.
The ARN of the Lambda function that is used as your canary's engine. For more information about Lambda ARN format, see Resources and Conditions for Lambda Actions.
Specifies the runtime version to use for the canary. For more information about runtime versions, see Canary Runtime Versions.
If this canary is to test an endpoint in a VPC, this structure contains information about the subnets and security groups of the VPC endpoint. For more information, see Running a Canary in a VPC.
The IDs of the VPC where this canary is to run.
The IDs of the subnets where this canary is to run.
The IDs of the security groups for this canary.
If this canary performs visual monitoring by comparing screenshots, this structure contains the ID of the canary run to use as the baseline for screenshots, and the coordinates of any parts of the screen to ignore during the visual monitoring comparison.
An array of screenshots that are used as the baseline for comparisons during visual monitoring.
A structure representing a screenshot that is used as a baseline during visual monitoring comparisons made by the canary.
The name of the screenshot. This is generated the first time the canary is run after the UpdateCanary operation that specified for this canary to perform visual monitoring.
Coordinates that define the part of a screen to ignore during screenshot comparisons. To obtain the coordinates to use here, use the CloudWatch console to draw the boundaries on the screen. For more information, see Editing or deleting a canary
The ID of the canary run that produced the baseline screenshots that are used for visual monitoring comparisons by this canary.
The list of key-value pairs that are associated with the canary.
A structure that contains the configuration for canary artifacts, including the encryption-at-rest settings for artifacts that the canary uploads to Amazon S3.
A structure that contains the configuration of encryption settings for canary artifacts that are stored in Amazon S3.
The encryption method to use for artifacts created by this canary. Specify SSE_S3 to use server-side encryption (SSE) with an Amazon S3-managed key. Specify SSE-KMS to use server-side encryption with a customer-managed KMS key.
If you omit this parameter, an Amazon Web Services-managed KMS key is used.
The ARN of the customer-managed KMS key to use, if you specify SSE-KMS for EncryptionMode
