Network.AWS.ApplicationAutoScaling.DescribeScalingActivities

Provides descriptive information for scaling activities with a specified service namespace.

You can filter the results in a service namespace with the ResourceId and ScalableDimension parameters.

Scaling activities are triggered by CloudWatch alarms that are associated with scaling policies. To view the existing scaling policies for a service namespace, see DescribeScalingPolicies. To create a new scaling policy or update an existing one, see PutScalingPolicy.

Request Lenses

dsaScalableDimension :: Lens' DescribeScalingActivities (Maybe ScalableDimension)

The scalable dimension associated with the scaling activity. The scalable dimension contains the service namespace, resource type, and scaling property, such as 'ecs:service:DesiredCount' for the desired task count of an Amazon ECS service. If you specify a scalable dimension, you must also specify a resource ID.

dsaResourceId :: Lens' DescribeScalingActivities (Maybe Text)

The unique identifier string for the resource associated with the scaling activity. For Amazon ECS services, this value is the resource type, followed by the cluster name and service name, such as 'service\/default\/sample-webapp'. If you specify a scalable dimension, you must also specify a resource ID.

dsaNextToken :: Lens' DescribeScalingActivities (Maybe Text)

The NextToken value returned from a previous paginated DescribeScalingActivities request. Pagination continues from the end of the previous results that returned the NextToken value. This value is null when there are no more results to return.

dsaMaxResults :: Lens' DescribeScalingActivities (Maybe Int)

The maximum number of scaling activity results returned by DescribeScalingActivities in paginated output. When this parameter is used, DescribeScalingActivities returns up to MaxResults results in a single page along with a NextToken response element. The remaining results of the initial request can be seen by sending another DescribeScalingActivities request with the returned NextToken value. This value can be between 1 and 50. If this parameter is not used, then DescribeScalingActivities returns up to 50 results and a NextToken value, if applicable.

dsaServiceNamespace :: Lens' DescribeScalingActivities ServiceNamespace

The namespace for the AWS service that the scaling activity is associated with. For more information, see AWS Service Namespaces in the Amazon Web Services General Reference.

Response Lenses

dsarsScalingActivities :: Lens' DescribeScalingActivitiesResponse [ScalingActivity]

A list of scaling activity objects.

dsarsNextToken :: Lens' DescribeScalingActivitiesResponse (Maybe Text)

The NextToken value to include in a future DescribeScalingActivities request. When the results of a DescribeScalingActivities request exceed MaxResults, this value can be used to retrieve the next page of results. This value is null when there are no more results to return.

dsarsResponseStatus :: Lens' DescribeScalingActivitiesResponse Int

The response status code.
