AWS Aurora MySQL Serverless CPU utilization is above 10 even though its is not processing any requests.

I have created rds aurora MySQL serverless cluster with 2 capacity units in AWS custom VPC which having three different subnets. But it always showing average CPU utilization is 10 to 15 %. Even there is no processing. It is always shown CPU usage even when RDS cluster is in idle state. How to check? How to fix the issue?

Hey @Latchu, you can try using the Amazon RDS performance insights. It's a service that helps you monitor and tune the performance of the data]base. It's easy to use as its meant for nonexperts. 

Log in to the Amazon RDS Management Console and enable performance insights when creating or modifying an RDS engine. Then go to the performance insights dashboard to start monitoring performance.

It is serverless so you cannot do anything about it except for the schema, stored procedures, functions, and data. AWS is managing it.

AWS can do all sort of things to it to manage and provision resources to it. Hence, the CPU usage among other things.

Performance insight isn't available for serverless.
