Configuring Displayed Metrics

The Agent of an RDS DB instance monitors the metrics and status of the DB instance only and does not collect other data except the monitoring metrics.

Description

This section describes the RDS metrics that can be monitored by Cloud Eye as well as their namespaces and dimensions. You can use APIs provided by Cloud Eye to query the monitoring metrics and alarms generated for RDS.

Namespace

SYS.RDS
