Describe step scaling policies for Application Auto Scaling using the AWS CLI

You can describe all scaling policies for a service namespace using the describe-scaling-policies command. The following example describes all scaling policies for all Amazon ECS services. To list them for a specific Amazon ECS service only add the --resource-id option.

aws application-autoscaling describe-scaling-policies --service-namespace ecs

You can filter the results to just the step scaling policies using the --query parameter. For more information about the syntax for query, see Controlling command output from the AWS CLI in the AWS Command Line Interface User Guide.

Linux, macOS, or Unix

aws application-autoscaling describe-scaling-policies --service-namespace ecs \
  --query 'ScalingPolicies[?PolicyType==`StepScaling`]'

Windows

aws application-autoscaling describe-scaling-policies --service-namespace ecs ^
  --query "ScalingPolicies[?PolicyType==`StepScaling`]"

The following is example output.
