Describes the scaling policies for the specified service 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 Source #
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. *appstream:fleet:DesiredCapacity
- The desired capacity of an AppStream 2.0 fleet. *dynamodb:table:ReadCapacityUnits
- The provisioned read capacity for a DynamoDB table. *dynamodb:table:WriteCapacityUnits
- The provisioned write capacity for a DynamoDB table. *dynamodb:index:ReadCapacityUnits
- The provisioned read capacity for a DynamoDB global secondary index. *dynamodb:index:WriteCapacityUnits
- The provisioned write capacity for a DynamoDB global secondary index.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 isservice
and the unique identifier is the cluster name and service name. Example:servicedefaultsample-webapp
. * Spot fleet request - The resource type isspot-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 isinstancegroup
and the unique identifier is the cluster ID and instance group ID. Example:instancegroupj-2EEZNYKUA1NTVig-1791Y4E1L8YI0
. * AppStream 2.0 fleet - The resource type isfleet
and the unique identifier is the fleet name. Example:fleet/sample-fleet
. * DynamoDB table - The resource type istable
and the unique identifier is the resource ID. Example:table/my-table
. * DynamoDB global secondary index - The resource type isindex
and the unique identifier is the resource ID. Example:tablemy-tableindex/my-table-index
.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 toMaxResults
results at a time, along with aNextToken
value. To get the next set of results, include theNextToken
value in a subsequent call. If this parameter is not used, the operation returns up to 50 results and aNextToken
value, if applicable.dServiceNamespace
- The namespace of the AWS service. For more information, see AWS Service Namespaces in the Amazon Web Services General Reference .
data DescribeScalingPolicies Source #
See: describeScalingPolicies
smart constructor.

and the unique identifier is the cluster ID and instance group ID. Example: instancegroupj-2EEZNYKUA1NTVig-1791Y4E1L8YI0
. * AppStream 2.0 fleet - The resource type is fleet
and the unique identifier is the fleet name. Example: fleet/sample-fleet

and the unique identifier is the resource ID. Example: table/my-table
. * DynamoDB global secondary index - The resource type is index
and the unique identifier is the resource ID. Example: tablemy-tableindex/my-table-index

dNextToken :: Lens' DescribeScalingPolicies (Maybe Text) Source #
The token for the next set of results.
dMaxResults :: Lens' DescribeScalingPolicies (Maybe Int) Source #
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.
