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`]"
