Here are the necessary tools and metrics to use for monitoring the AWS RDS service. The AWS RDS is also called Relational Database Service. When a user defines a database for RDS service, it’s their responsibility to monitor the service.
The metrics you can monitor are network throughput; I/O for reading, writing, and/or metadata operations; client connections; and burst-credit balances for DB instances. Here are the available RDS instance types.
