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 ECS service recommendations.

(structure)

Describes a filter that returns a more specific list of Amazon ECS service recommendations. Use this filter with the GetECSServiceRecommendations action.

name -> (string)

The name of the filter.

Specify Finding to return recommendations with a specific finding classification.

Specify FindingReasonCode to return recommendations with a specific finding reason code.

values -> (list)

The value of the filter.

The valid values for this parameter are as follows:

  • If you specify the name parameter as Finding , specify Optimized , NotOptimized , or Unavailable .

  • If you specify the name parameter as FindingReasonCode , specify CPUUnderprovisioned , CPUOverprovisioned , MemoryUnderprovisioned , or MemoryOverprovisioned .

    "name": "Finding"|"FindingReasonCode",
    "values": ["string", ...]
  }
  ...
]

--account-ids (list)

Return the ECS service recommendations to the specified Amazon Web Services account IDs.

You can only specify one account ID per request.

(string)

Syntax:

"string" "string" ...

--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.

--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.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

  • TARGET_TRACKING_SCALING_MEMORY — If the ECS service is configured to use target scaling on memory, Compute Optimizer doesn’t generate memory recommendations.

For more information about step scaling and target scaling, see Step scaling policies for Application Auto Scaling and Target tracking scaling policies for Application Auto Scaling in the Application Auto Scaling User Guide .

taskDefinitionArn -> (string)

The task definition ARN used by the tasks in the ECS service.

utilizationMetrics -> (list)

An array of objects that describe the utilization metrics of the ECS service.

(structure)

Describes the utilization metric of an Amazon ECS service.

To determine the performance difference between your current ECS service and the recommended option, compare the utilization metric data of your service against its projected utilization metric data.
