Identify MariaDB, MySQL, or PostgreSQL database server resources have been underutilized for an extended time over the past 7 days.
By default, an database instance is considered underutilized when meets the following criteria:
- The average CPU & IO utilization has been less than 30% for the last 7 days.
- The average CPU & IO utilization has been more than 5% for the last 7 days.
To reduce your costs and efficiently manage your resources, we recommend that you reduce the compute size (vCores) by half.
