Network.AWS.ApplicationAutoScaling.DescribeScalingPolicies

Provides descriptive information about the scaling policies in the specified namespace.

You can filter the results using the ResourceId , ScalableDimension , and PolicyNames parameters.

To create a scaling policy or update an existing one, see PutScalingPolicy . If you are no longer using a scaling policy, you can delete it using DeleteScalingPolicy .

This operation returns paginated results.

Creating a Request

describeScalingPolicies

Arguments

:: ServiceNamespace

dServiceNamespace

-> DescribeScalingPolicies

Creates a value of DescribeScalingPolicies with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• dPolicyNames - The names of the scaling policies to describe.
• dScalableDimension - The scalable dimension. This string consists of the service namespace, resource type, and scaling property. If you specify a scalable dimension, you must also specify a resource ID. * ecs:service:DesiredCount - The desired task count of an ECS service. * ec2:spot-fleet-request:TargetCapacity - The target capacity of a Spot fleet request. * elasticmapreduce:instancegroup:InstanceCount - The instance count of an EMR Instance Group.
• dResourceId - The identifier of the resource associated with the scaling policy. This string consists of the resource type and unique identifier. If you specify a scalable dimension, you must also specify a resource ID. * ECS service - The resource type is service and the unique identifier is the cluster name and service name. Example: servicedefaultsample-webapp . * Spot fleet request - The resource type is spot-fleet-request and the unique identifier is the Spot fleet request ID. Example: spot-fleet-request/sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE . * EMR cluster - The resource type is instancegroup and the unique identifier is the cluster ID and instance group ID. Example: instancegroupj-2EEZNYKUA1NTVig-1791Y4E1L8YI0 .
• dNextToken - The token for the next set of results.
• dMaxResults - The maximum number of scalable target results. This value can be between 1 and 50. The default value is 50. If this parameter is used, the operation returns up to MaxResults results at a time, along with a NextToken value. To get the next set of results, include the NextToken value in a subsequent call. If this parameter is not used, the operation returns up to 50 results and a NextToken value, if applicable.
• dServiceNamespace - The namespace of the AWS service. For more information, see AWS Service Namespaces in the Amazon Web Services General Reference .
