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.

(string)

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.

values -> (list)

The value of the filter.

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.
    • **CPUUnderprovisioned ** — The instance’s CPU configuration doesn’t meet the performance requirements of your workload and there is an alternative instance type that provides better CPU performance.
    • **MemoryOverprovisioned ** — The instance’s memory configuration can be sized down while still meeting the performance requirements of your workload.

cpuVendorArchitectures -> (list)

Specifies the CPU vendor and architecture for Amazon EC2 instance and Auto Scaling group recommendations.

For example, when you specify AWS_ARM64 with:

  • A GetEC2InstanceRecommendations or GetAutoScalingGroupRecommendations request, Compute Optimizer returns recommendations that consist of Graviton instance types only.
  • A GetEC2RecommendationProjectedMetrics request, Compute Optimizer returns projected utilization metrics for Graviton instance type recommendations only.
  • A ExportEC2InstanceRecommendations or ExportAutoScalingGroupRecommendations request, Compute Optimizer exports recommendations that consist of Graviton instance types only.

Shorthand Syntax:

cpuVendorArchitectures=string,string

JSON Syntax:

{
  "cpuVendorArchitectures": ["AWS_ARM64"|"CURRENT", ...]
}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.
