Amazon Relational Database Service

Amazon Relational Database Service (RDS) is a database service that simplifies the setup, operation, and scaling of relational databases in the AWS cloud.

You must configure cloud connections to monitor this entity. See Set up Cisco AppDynamics Cloud Collectors to Monitor AWS. For detailed visibility, such as query profiling and streamlined troubleshooting, install Database Monitoring.

Cisco Cloud Observability displays AWS entities on the Observe page. Metrics are displayed for specific entity instances in the list and detail views.
