Method Detail

create

@Stability(value=Stable)
public static CfnScalingPolicy.Builder create(software.constructs.Construct scope,
                                                                       String id)

Parameters:

scope - - scope in which this resource is defined. This parameter is required.

id - - scoped id of the resource. This parameter is required.

Returns:

a new instance of CfnScalingPolicy.CustomizedMetricSpecificationProperty.Builder.

policyName

@Stability(value=Stable)
public CfnScalingPolicy.Builder policyName(String policyName)

The name of the scaling policy.

Updates to the name of a target tracking scaling policy are not supported, unless you also update the metric used for scaling. To change only a target tracking scaling policy's name, first delete the policy by removing the existing AWS::ApplicationAutoScaling::ScalingPolicy resource from the template and updating the stack. Then, recreate the resource with the same settings and a different name.

Parameters:

policyName - The name of the scaling policy. This parameter is required.

Returns:

this

policyType

@Stability(value=Stable)
public CfnScalingPolicy.Builder policyType(String policyType)

The scaling policy type.

The following policy types are supported:

TargetTrackingScaling —Not supported for Amazon EMR

StepScaling —Not supported for DynamoDB, Amazon Comprehend, Lambda, Amazon Keyspaces, Amazon MSK, Amazon ElastiCache, or Neptune.

Parameters:

policyType - The scaling policy type. This parameter is required.

Returns:

this

resourceId

@Stability(value=Stable)
public CfnScalingPolicy.Builder resourceId(String resourceId)

The identifier of the resource associated with the scaling policy.

This string consists of the resource type and unique identifier.

• ECS service - The resource type is service and the unique identifier is the cluster name and service name. Example: service/default/sample-webapp .
• Spot Fleet - 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: instancegroup/j-2EEZNYKUA1NTV/ig-1791Y4E1L8YI0 .

• 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 .
• Amazon Keyspaces table - The resource type is table and the unique identifier is the table name. Example: keyspace/mykeyspace/table/mytable .
• Amazon MSK cluster - The resource type and unique identifier are specified using the cluster ARN. Example: arn:aws:kafka:us-east-1:123456789012:cluster/demo-cluster-1/6357e0b2-0e6a-4b86-a0b4-70df934c2e31-5 .
