Enhanced infrastructure metrics
Enhanced infrastructure metrics is a paid feature of Compute Optimizer that applies to Amazon EC2 instances, instances that are part of Auto Scaling groups, and Amazon RDS DB instances. This recommendation preference extends the utilization metrics analysis lookback period to up to 93 days, compared to the default 14-dayperiod. This gives Compute Optimizer a longer history of utilization metrics data to analyze. You need to activate the enhanced infrastructure metrics preference. For more information, see Organization, account, and resource level.
Required permissions
You must have the appropriate permissions to activate and deactivate enhanced infrastructure metrics. For more information, see Policies to grant access to manage Compute Optimizer recommendation preferences.
Organization, account, and resource level
You can activate enhanced infrastructure metrics using the Compute Optimizer console, AWS Command Line Interface (AWS CLI), and AWS SDKs. In the console, you can activate the feature in the following three areas, with each providing a different level of activation.
-
At the resource level, you can activate enhanced infrastructure metrics for the individual resource that you're viewing. For example, the Instance details page for an individual EC2 instance provides the option to activate the enhanced infrastructure metrics feature only for that EC2 instance. For more information, see Activating enhanced infrastructure metrics at the resource level later in this guide.
Note
Resource-level preferences override account-level preferences, and account-level preferences override organization-level preferences. For an EC2 instance that is part of an Auto Scaling group, the Auto Scaling group recommendation preference overrides that of the individual instance.
-
For an individual AWS account holder, you can activate the enhanced infrastructure metrics feature for all EC2 instances in the account that meet your resource type and AWS Region criteria. EC2 instance preferences at the account level apply to standalone instances and instances that are part of Auto Scaling groups. For more information, see Activating enhanced infrastructure metrics at the organization or account level later in this guide.
-
The account manager or the delegated administrator of an AWS Organization can activate the enhanced infrastructure metrics feature for all resources in all member accounts of the organization that meet your resource type and AWS Region criteria. EC2 instance preferences at the organization level apply to standalone instances and instances that are part of Auto Scaling groups in all member accounts. For more information, see Activating enhanced infrastructure metrics at the organization or account level later in this guide.
After you activate the enhanced infrastructure metrics feature, Compute Optimizer applies the preference the next time recommendations are refreshed. This can take up to 24 hours. To confirm that your resource recommendations have enhanced infrastructure metrics enabled, see Confirming the status of enhanced infrastructure metrics.
Compute Optimizer considers updated preferences the next time that it generates recommendations. Until then, a pending status is affixed to your update preference (for example, Active-pending or Inactive-pending). To confirm if your resource recommendations are taking enhanced infrastructure metrics into consideration, see Confirming the status of enhanced infrastructure metrics.
Confirming the status of enhanced infrastructure metrics
After you activate the enhanced infrastructure metrics recommendation preference, Compute Optimizer applies the preference the next time that recommendations are refreshed. This can take up to 24 hours. The Effective enhanced infrastructure metrics column in the Resource Recommendations page confirms that the recommendations listed are taking the three-month look-back period into consideration. An Active status confirms the recommendation listed is considering the longer look-back period. An Inactive status confirms that the recommendation isn't yet considering the longer look-back period.
