Configuring Displayed Metrics

Updated on 2024-10-14 GMT+08:00

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

Notes

  • The RDS Agent monitors RDS DB instances and collects monitoring metrics only.
  • The monitoring interval is 1 minute.

Namespace

SYS.RDS
