How to check current ACU usage for Amazon aurora serverless postgres V2 DB

According to https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless-v2.how-it-works.html

Each ACU is a combination of approximately 2 gibibytes (GiB) of memory, corresponding CPU, and networking. You specify the database capacity range using this unit of measure. The ServerlessDatabaseCapacity and ACUUtilization metrics help you to determine how much capacity your database is actually using and where that capacity falls within the specified range.

So look for Cloudwatch metrics: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless-v2.setting-capacity.html
