Options

--account-ids (list)

The IDs of the AWS accounts 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 accounts for which you want to return Auto Scaling group recommendations.

Only one account ID can be specified per request.

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 that describe 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.

This filter is used with the GetAutoScalingGroupRecommendations and GetEC2InstanceRecommendations actions.

name -> (string)

The name of the filter.

Specify Finding to return recommendations with a specific finding classification (e.g., Overprovisioned ).

Specify RecommendationSourceType to return recommendations of a specific resource type (e.g., AutoScalingGroup ).

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 specified the name parameter as Finding and you want to filter results for Auto Scaling groups.

  • Specify Underprovisioned , Overprovisioned , or Optimized if you specified the name parameter as Finding and you want to filter results for EC2 instances.

  • Specify Ec2Instance or AutoScalingGroup if you specified the name parameter as RecommendationSourceType .

(string)

Shorthand Syntax:

name=string,values=string,string ...

JSON Syntax:

[
  {
    "name": "Finding"|"RecommendationSourceType",
    "values": ["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.

See ‘aws help’ for descriptions of global parameters.

  • **Optimized ** —An Auto Scaling group is considered optimized when Compute Optimizer determines that the group is correctly provisioned to run your workload based on the chosen instance type. For optimized resources, Compute Optimizer might recommend a new generation instance type.

utilizationMetrics -> (list)

An array of objects that describe the utilization metrics of the Auto Scaling group.

(structure)

Describes a utilization metric of a resource, such as an Amazon EC2 instance.

Compare the utilization metric data of your resource against its projected utilization metric data to determine the performance difference between your current resource and the recommended option.

name -> (string)

The name of the utilization metric.

The following utilization metrics are available:

  • Cpu - The percentage of allocated EC2 compute units that are currently in use on the instance. This metric identifies the processing power required to run an application on the instance. Depending on the instance type, tools in your operating system can show a lower percentage than CloudWatch when the instance is not allocated a full processor core. Units: Percent

  • Memory - The percentage of memory that is currently in use on the instance. This metric identifies the amount of memory required to run an application on the instance. Units: Percent

Note

The Memory metric is returned only for resources that have the unified CloudWatch agent installed on them. For more information, see Enabling Memory Utilization with the CloudWatch Agent .

  • EBS_READ_OPS_PER_SECOND - The completed read operations from all EBS volumes attached to the instance in a specified period of time. Unit: Count

  • EBS_WRITE_OPS_PER_SECOND - The completed write operations to all EBS volumes attached to the instance in a specified period of time. Unit: Count

statistic -> (string)

The statistic of the utilization metric.

The following statistics are available:

  • Average - This is the value of Sum / SampleCount during the specified period, or the average value observed during the specified period.
