To describe scalable targets

The following describe-scalable-targets example describes the scalable targets for the ecs service namespace.

aws application-autoscaling describe-scalable-targets \
    --service-namespace ecs

Output:

{
    "ScalableTargets": [
        {
            "ServiceNamespace": "ecs",
            "ScalableDimension": "ecs:service:DesiredCount",
            "ResourceId": "service/default/web-app",
            "MinCapacity": 1,
            "MaxCapacity": 10,
