Configuring Displayed Metrics

The RDS Agent monitors RDS DB instances and collects monitoring metrics only.

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.

The monitoring interval can be 1 minute, 1 second, or 5 seconds. The default monitoring interval is 1 minute. To enable Monitoring by Seconds, see Configuring Monitoring by Seconds.

Namespace of RDS for MySQL instance metrics: SYS. RDS
Namespace of database proxy metrics: SYS.DBPROXY
