Provides descriptive information about the scaling activities in the specified namespace from the previous six weeks.
You can filter the results using the ResourceId
and ScalableDimension
parameters.
Scaling activities are triggered by CloudWatch alarms that are associated with scaling policies. To view the scaling policies for a service namespace, see DescribeScalingPolicies
. To create a scaling policy or update an existing one, see PutScalingPolicy
.
This operation returns paginated results.

Creating a Request
describeScalingActivities Source #
Creates a value of DescribeScalingActivities
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
desScalableDimension
- 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. *rds:cluster:ReadReplicaCount
- The count of Aurora Replicas in an Aurora DB cluster. Available for Aurora MySQL-compatible edition. *sagemaker:variant:DesiredInstanceCount
- The number of EC2 instances for an Amazon SageMaker model endpoint variant.desResourceId
- The identifier of the resource associated with the scaling activity. 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
. * Aurora DB cluster - The resource type iscluster
and the unique identifier is the cluster name. Example:cluster:my-db-cluster
. * Amazon SageMaker endpoint variants - The resource type isvariant
and the unique identifier is the resource ID. Example:endpointmy-end-pointvariant/KMeansClustering
.desNextToken
- The token for the next set of results.desMaxResults
- The maximum number of scalable targets. 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.desServiceNamespace
- The namespace of the AWS service. For more information, see AWS Service Namespaces in the Amazon Web Services General Reference .
