Opt in AWS Compute Optimizer for Trusted Advisor checks

Compute Optimizer is a service that analyzes the configuration and utilization metrics of your AWS resources. This service reports whether your resources are correctly configured for efficiency and reliability. It also suggests improvements you can implement to improve workload performance. With Compute Optimizer, you view the same recommendations in your Trusted Advisor checks.

You can opt in either your AWS account only, or all member accounts that are part of an organization in AWS Organizations. For more information, see Getting started in the AWS Compute Optimizer User Guide.

Once you opt in for Compute Optimizer, the following checks receive data from your Lambda functions and Amazon EBS volumes. It can take up to 12 hours to generate the findings and optimization recommendations. It can then take up to 48 hours to view your results in Trusted Advisor for the following checks:

Cost optimization

  • Amazon EBS over-provisioned volumes

  • AWS Lambda over-provisioned functions for memory size

Performance

  • Amazon EBS under-provisioned volumes

  • AWS Lambda under-provisioned functions for memory size

Notes

  • Results for these check are automatically refreshed at least once daily, and refresh requests are not allowed. It might take a few hours for changes to appear. You can use the Trusted Advisor console to exclude resources from checks that automatically refresh. You can use the BatchUpdateRecommendationResourceExclusion API to exclude resources from any check except Trusted Advisor Priority recommendation resources.

  • Trusted Advisor already has the Underutilized Amazon EBS Volumes and the Overutilized Amazon EBS Magnetic Volumes checks.

    After you opt in with Compute Optimizer, we recommend that you use the new Amazon EBS over-provisioned volumes and Amazon EBS under-provisioned volumes checks instead.
