Options

--account-ids (list)

The ID of the Amazon Web Services account for which to return Auto Scaling group recommendations.

If your account is the management account of an organization, use this parameter to specify the member account for which you want to return Auto Scaling group recommendations.

Only one account ID can be specified per request.

(string)

Syntax:

"string" "string" ...

--auto-scaling-group-arns (list)

The Amazon Resource Name (ARN) of the Auto Scaling groups for which to return recommendations.

Syntax:

"string" "string" ...

--next-token (string)

The token to advance to the next page of Auto Scaling group recommendations.

--max-results (integer)

The maximum number of Auto Scaling group recommendations to return with a single request.

To retrieve the remaining results, make another request with the returned nextToken value.

--filters (list)

An array of objects to specify a filter that returns a more specific list of Auto Scaling group recommendations.

(structure)

Describes a filter that returns a more specific list of recommendations. Use this filter with the GetAutoScalingGroupRecommendations and GetEC2InstanceRecommendations actions.

You can use EBSFilter with the GetEBSVolumeRecommendations action, LambdaFunctionRecommendationFilter with the GetLambdaFunctionRecommendations action, and JobFilter with the DescribeRecommendationExportJobs action.

name -> (string)

The name of the filter.

Specify Finding to return recommendations with a specific finding classification. For example, Underprovisioned .

Specify RecommendationSourceType to return recommendations of a specific resource type. For example, Ec2Instance .

Specify FindingReasonCodes to return recommendations with a specific finding reason code. For example, CPUUnderprovisioned .

Specify InferredWorkloadTypes to return recommendations of a specific inferred workload. For example, Redis .

You can filter your EC2 instance recommendations by tag:key and tag-key tags.

A tag:key is a key and value combination of a tag assigned to your recommendations. Use the tag key in the filter name and the tag value as the filter value. For example, to find all recommendations that have a tag with the key of Owner and the value of TeamA , specify tag:Owner for the filter name and TeamA for the filter value.

A tag-key is the key of a tag assigned to your recommendations. Use this filter to find all of your recommendations that have a tag with a specific key. This doesn’t consider the tag value. For example, you can find your recommendations with a tag key value of Owner or without any tag keys assigned.

The valid values for this parameter are as follows, depending on what you specify for the name parameter and the resource type that you wish to filter results for:

  • Specify Optimized or NotOptimized if you specify the name parameter as Finding and you want to filter results for Auto Scaling groups.
  • Specify Underprovisioned , Overprovisioned , or Optimized if you specify the name parameter as Finding and you want to filter results for EC2 instances.
  • Specify Ec2Instance or AutoScalingGroup if you specify the name parameter as RecommendationSourceType .
  • Specify one of the following options if you specify the name parameter as FindingReasonCodes :
    • **CPUOverprovisioned ** — The instance’s CPU configuration can be sized down while still meeting the performance requirements of your workload.
