put_scheduled_action

put_scheduled_action(**kwargs)

Creates or updates a scheduled action for an Application Auto Scaling scalable target.

Each scalable target is identified by a service namespace, resource ID, and scalable dimension. A scheduled action applies to the scalable target identified by those three attributes. You cannot create a scheduled action until you have registered the resource as a scalable target.

When start and end times are specified with a recurring schedule using a cron expression or rates, they form the boundaries for when the recurring action starts and stops.

To update a scheduled action, specify the parameters that you want to change. If you don't specify start and end times, the old values are deleted.

For more information, see Scheduled scaling in the Application Auto Scaling User Guide .

Note

If a scalable target is deregistered, the scalable target is no longer available to run scheduled actions. Any scheduled actions that were specified for the scalable target are deleted.

Parameters
  • ServiceNamespace (string) --

    [REQUIRED]

    The namespace of the Amazon Web Services service that provides the resource. For a resource provided by your own application or service, use custom-resource instead.

  • Schedule (string) --

    The schedule for this action. The following formats are supported:

    • At expressions - " at(yyyy-mm-ddThh:mm:ss) "
    • Rate expressions - " rate(valueunit) "
    • Cron expressions - " cron(fields) "

    At expressions are useful for one-time schedules. Cron expressions are useful for scheduled actions that run periodically at a specified date and time, and rate expressions are useful for scheduled actions that run at a regular interval.

    At and cron expressions use Universal Coordinated Time (UTC) by default.

    The cron format consists of six fields separated by white spaces: [Minutes] [Hours] [Day_of_Month] [Month] [Day_of_Week] [Year].

    For rate expressions, value is a positive integer and unit is minute | minutes | hour | hours | day | days .

    For more information and examples, see Example scheduled actions for Application Auto Scaling in the Application Auto Scaling User Guide .

  • Timezone (string) --

    Specifies the time zone used when setting a scheduled action by using an at or cron expression. If a time zone is not provided, UTC is used by default.

    Valid values are the canonical names of the IANA time zones supported by Joda-Time (such as Etc/GMT+9 or Pacific/Tahiti ). For more information, see https://www.joda.org/joda-time/timezones.html.

    • SageMaker endpoint variant - The resource type is variant and the unique identifier is the resource ID. Example: endpoint/my-end-point/variant/KMeansClustering .
    • Custom resources are not supported with a resource type. This parameter must specify the OutputValue from the CloudFormation template stack used to access the resources. The unique identifier is defined by the service provider. More information is available in our GitHub repository.
    • Amazon Comprehend document classification endpoint - The resource type and unique identifier are specified using the endpoint ARN. Example: arn:aws:comprehend:us-west-2:123456789012:document-classifier-endpoint/EXAMPLE .
    • Amazon Comprehend entity recognizer endpoint - The resource type and unique identifier are specified using the endpoint ARN. Example: arn:aws:comprehend:us-west-2:123456789012:entity-recognizer-endpoint/EXAMPLE .
    • Lambda provisioned concurrency - The resource type is function and the unique identifier is the function name with a function version or alias name suffix that is not $LATEST . Example: function:my-function:prod or function:my-function:1 .

  • EndTime (datetime) -- The date and time for the recurring schedule to end, in UTC.
  • ScalableTargetAction (dict) --

    The new minimum and maximum capacity. You can set both values or just one. At the scheduled time, if the current capacity is below the minimum capacity, Application Auto Scaling scales out to the minimum capacity. If the current capacity is above the maximum capacity, Application Auto Scaling scales in to the maximum capacity.

    • MinCapacity (integer) --

      The minimum capacity.

      When the scheduled action runs, the resource will have at least this much capacity, but it might have more depending on other settings, such as the target utilization level of a target tracking scaling policy.

    • MaxCapacity (integer) --

      The maximum capacity.

      Although you can specify a large maximum capacity, note that service quotas may impose lower limits. Each service has its own default quotas for the maximum capacity of the resource. If you want to specify a higher limit, you can request an increase. For more information, consult the documentation for that service. For information about the default quotas for each service, see Service endpoints and quotas in the Amazon Web Services General Reference .
