I/O activity, DB Instance connections, and number of users
DB Engine Version Management
username, I/O activity, and DB Instance connections
compute/memory/storage capacity utilization, I/O activity, and DB Instance connections
Explanations:
While I/O activity and DB Instance connections are part of the CloudWatch metrics, “number of users” is not a standard CloudWatch metric for RDS.
DB Engine Version Management is not a metric provided by CloudWatch; it’s a feature related to database management, not operational monitoring.
Username is not a CloudWatch metric. CloudWatch focuses on operational metrics like I/O activity and DB Instance connections.
This option includes the correct CloudWatch metrics for Amazon RDS: compute, memory, and storage capacity utilization, I/O activity, and DB Instance connections.
