Use DescribePolicies with a CLI

Example 1: To describe the scaling policies of a specified group

This example describes the scaling policies for the specified Auto Scaling group.

aws autoscaling describe-policies \
    --auto-scaling-group-name my-asg

Output:

Example 2: To describe the scaling policies of a specified name

To return specific scaling policies, use the --policy-names option.

aws autoscaling describe-policies \
    --auto-scaling-group-name my-asg \
    --policy-names cpu40-target-tracking-scaling-policy

See example 1 for sample output.

For more information, see Dynamic scaling in the Amazon EC2 Auto Scaling User Guide.

Example 3: To describe a number of scaling policies

To return a specific number of policies, use the --max-items option.

aws autoscaling describe-policies \
    --auto-scaling-group-name my-asg \
    --max-items 1

See example 1 for sample output.

If the output includes a NextToken field, use the value of this field with the --starting-token option in a subsequent call to get the additional policies.

aws autoscaling describe-policies --auto-scaling-group-name my-asg --starting-token Z3M3LMPEXAMPLE

For more information, see Dynamic scaling in the Amazon EC2 Auto Scaling User Guide.
