What are the main monitoring or other parameters to check if the instance is underutilized—the MySQL RDS instance?


Hi Team,

We have a MySQL RDS instance with the 'db.m5.8xlarge' type, and I want to share a report with the customer to see if the instance is underutilized or not. I have checked the CPU utilization and free memory monitoring parameters, but I want to know what other things should be checked to decide on the utilization.

Please share some detailed explanations.

The CloudWatch metrics I often see for RDS are performance-related metrics such as "ReadIOPS", "ReadLatency", and "ReadThroughput".
By looking at these metrics, you will be able to understand whether loading is occurring to some extent.

If your AWS account is subscribed to an AWS support plan higher than business support, you may be able to check for RDS with low usage by checking Trusted Advisor.

The AWS RDS Console has a default metrics page that will show you the common metrics in a dashboard such as CPU utilization, IOPS, memory utilization, etc. Just click on the monitoring tab from the database detail page.
