Utilizzo DescribeScalingPolicies con un AWS SDK o una CLI

Come descrivere le policy di dimensionamento

Questo comando di esempio descrive le policy di dimensionamento per il namespace del servizio ecs.

Comando:

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

Output:
