Instance Attribute Details

#policy_nameString (readonly)

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.

end

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.

PredictiveScaling —Only supported for Amazon ECS
