get_ec2_recommendation_projected_metrics#

ComputeOptimizer.Client.get_ec2_recommendation_projected_metrics(**kwargs)#

Returns the projected utilization metrics of Amazon EC2 instance recommendations.

Note

The Cpu and Memory metrics are the only projected utilization metrics returned when you run this action. Additionally, 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.

Request Syntax

response = client.get_ec2_recommendation_projected_metrics(
    instanceArn='string',
    stat='Maximum'|'Average',
    period=123,
    startTime=datetime(2015, 1, 1),
    endTime=datetime(2015, 1, 1),
    recommendationPreferences={
        'cpuVendorArchitectures': [
            'AWS_ARM64'|'CURRENT',
        ]
    }
)
Parameters:

  • instanceArn (string) –

    [REQUIRED]

    The Amazon Resource Name (ARN) of the instances for which to return recommendation projected metrics.

  • stat (string) –

    [REQUIRED]

    The statistic of the projected metrics.

  • period (integer) –

    [REQUIRED]

    The granularity, in seconds, of the projected metrics data points.

  • startTime (datetime) –

    [REQUIRED]

    The timestamp of the first projected metrics data point to return.

  • endTime (datetime) –

    [REQUIRED]

    The timestamp of the last projected metrics data point to return.

  • recommendationPreferences (dict) –

    An object to specify the preferences for the Amazon EC2 recommendation projected metrics to return in the response.

    • 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 Graviton2 instance types only.

      • A GetEC2RecommendationProjectedMetrics request, Compute Optimizer returns projected utilization metrics for Graviton2 instance type recommendations only.

      • A ExportEC2InstanceRecommendations or ExportAutoScalingGroupRecommendations request, Compute Optimizer exports recommendations that consist of Graviton2 instance types only.

      • (string) –

Return type:

dict

Response Structure

  • (dict) –

    • recommendedOptionProjectedMetrics (list) –

      An array of objects that describes projected metrics.

      • (dict) –

        Describes a projected utilization metric of a recommendation option.

        Note

        The Cpu and Memory metrics are the only projected utilization metrics returned when you run the GetEC2RecommendationProjectedMetrics action. Additionally, 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.

        • recommendedInstanceType (string) –

          The recommended instance type.

        • rank (integer) –

          The rank of the recommendation option projected metric.

          The top recommendation option is ranked as 1.

          The projected metric rank correlates to the recommendation option rank. For example, the projected metric ranked as 1 is related to the recommendation option that is also ranked as 1 in the same response.

        • projectedMetrics (list) –

          An array of objects that describe a projected utilization metric.

          • (dict) –

            Describes a projected utilization metric of a recommendation option, such as an Amazon EC2 instance. This represents the projected utilization of a recommendation option had you used that resource during the analyzed period.

            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.

            Note

            The Cpu and Memory metrics are the only projected utilization metrics returned when you run the GetEC2RecommendationProjectedMetrics action. Additionally, 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.

            • name (string) –

              The name of the projected utilization metric.

              The following projected utilization metrics are returned:

              • Cpu - The projected percentage of allocated EC2 compute units that would be in use on the recommendation option had you used that resource during the analyzed period. This metric identifies the processing power required to run an application on the recommendation option. 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 would be in use on the recommendation option had you used that resource during the analyzed period. This metric identifies the amount of memory required to run an application on the recommendation option. 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.

            • timestamps (list) –

              The timestamps of the projected utilization metric.

              • (datetime) –

            • values (list) –

              The values of the projected utilization metrics.
