Options

--volume-arns (list)

The Amazon Resource Name (ARN) of the volumes for which to return recommendations.

(string)

Syntax:

"string" "string" ...

--next-token (string)

The token to advance to the next page of volume recommendations.

--max-results (integer)

The maximum number of volume 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 volume recommendations.

(structure)

Describes a filter that returns a more specific list of Amazon Elastic Block Store (Amazon EBS) volume recommendations. Use this filter with the GetEBSVolumeRecommendations action.

You can use LambdaFunctionRecommendationFilter with the GetLambdaFunctionRecommendations action, JobFilter with the DescribeRecommendationExportJobs action, and Filter with the GetAutoScalingGroupRecommendations and GetEC2InstanceRecommendations actions.

name -> (string)

The name of the filter.

Specify Finding to return recommendations with a specific finding classification (for example, NotOptimized ).

values -> (list)

The value of the filter.

The valid values are Optimized , or NotOptimized .

(string)

Shorthand Syntax:

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

JSON Syntax:

[
  {
    "name": "Finding",
    "values": ["string", ...]
  }
  ...
]

--account-ids (list)

The ID of the Amazon Web Services account for which to return volume 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 volume recommendations.

Only one account ID can be specified 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.

See ‘aws help’ for descriptions of global parameters.

Output

nextToken -> (string)

The token to use to advance to the next page of volume recommendations.

This value is null when there are no more pages of volume recommendations to return.

volumeRecommendations -> (list)

An array of objects that describe volume recommendations.

(structure)

Describes an Amazon Elastic Block Store (Amazon EBS) volume recommendation.

volumeArn -> (string)

The Amazon Resource Name (ARN) of the current volume.

accountId -> (string)

The Amazon Web Services account ID of the volume.

currentConfiguration -> (structure)

An array of objects that describe the current configuration of the volume.

volumeType -> (string)

The volume type.

This can be gp2 for General Purpose SSD, io1 or io2 for Provisioned IOPS SSD, st1 for Throughput Optimized HDD, sc1 for Cold HDD, or standard for Magnetic volumes.

volumeSize -> (integer)

The size of the volume, in GiB.

volumeBaselineIOPS -> (integer)

The baseline IOPS of the volume.

volumeBurstIOPS -> (integer)

The burst IOPS of the volume.

volumeBaselineThroughput -> (integer)

The baseline throughput of the volume.

volumeBurstThroughput -> (integer)

The burst throughput of the volume.

finding -> (string)

The finding classification of the volume.

Findings for volumes include:

  • **NotOptimized ** —A volume is considered not optimized when Compute Optimizer identifies a recommendation that can provide better performance for your workload.

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

utilizationMetrics -> (list)

An array of objects that describe the utilization metrics of the volume.

(structure)

Describes a utilization metric of an Amazon Elastic Block Store (Amazon EBS) volume.

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:

  • VolumeReadOpsPerSecond - The completed read operations per second from the volume in a specified period of time. Unit: Count

  • VolumeWriteOpsPerSecond - The completed write operations per second to the volume in a specified period of time. Unit: Count

  • VolumeReadBytesPerSecond - The bytes read per second from the volume in a specified period of time. Unit: Bytes

  • VolumeWriteBytesPerSecond - The bytes written to the volume in a specified period of time. Unit: Bytes

statistic -> (string)

The statistic of the utilization metric.

The Compute Optimizer API, Command Line Interface (CLI), and SDKs return utilization metrics using only the Maximum statistic, which is the highest value observed during the specified period.

The Compute Optimizer console displays graphs for some utilization metrics using the Average statistic, which is the value of Sum / SampleCount during the specified period. For more information, see Viewing resource recommendations in the Compute Optimizer User Guide . You can also get averaged utilization metric data for your resources using Amazon CloudWatch. For more information, see the Amazon CloudWatch User Guide .

value -> (double)

The value of the utilization metric.

lookBackPeriodInDays -> (double)

The number of days for which utilization metrics were analyzed for the volume.

volumeRecommendationOptions -> (list)

An array of objects that describe the recommendation options for the volume.

(structure)

Describes a recommendation option for an Amazon Elastic Block Store (Amazon EBS) instance.

configuration -> (structure)

An array of objects that describe a volume configuration.

volumeType -> (string)

The volume type.

This can be gp2 for General Purpose SSD, io1 or io2 for Provisioned IOPS SSD, st1 for Throughput Optimized HDD, sc1 for Cold HDD, or standard for Magnetic volumes.

volumeSize -> (integer)

The size of the volume, in GiB.

volumeBaselineIOPS -> (integer)

The baseline IOPS of the volume.

volumeBurstIOPS -> (integer)

The burst IOPS of the volume.

volumeBaselineThroughput -> (integer)

The baseline throughput of the volume.

volumeBurstThroughput -> (integer)

The burst throughput of the volume.

performanceRisk -> (double)

The performance risk of the volume recommendation option.

Performance risk is the likelihood of the recommended volume type meeting the performance requirement of your workload.

The value ranges from 0 - 4 , with 0 meaning that the recommended resource is predicted to always provide enough hardware capability. The higher the performance risk is, the more likely you should validate whether the recommendation will meet the performance requirements of your workload before migrating your resource.

rank -> (integer)

The rank of the volume recommendation option.

The top recommendation option is ranked as 1 .

lastRefreshTimestamp -> (timestamp)

The timestamp of when the volume recommendation was last refreshed.

errors -> (list)

An array of objects that describe errors of the request.

For example, an error is returned if you request recommendations for an unsupported volume.

(structure)

Describes an error experienced when getting recommendations.

For example, an error is returned if you request recommendations for an unsupported Auto Scaling group, or if you request recommendations for an instance of an unsupported instance family.

identifier -> (string)

The ID of the error.

code -> (string)

The error code.

message -> (string)

The message, or reason, for the error.
