This topic describes the metrics for the compute nodes in PoarDB-X V2.0 instances.

When you call an API operation provided by CloudMonitor, set the Namespace and Period parameters.

  • Set the Namespace parameter to acs_drds.
  • Set the Period parameter to an integral multiple of 60. The default value is 60. Unit: seconds.

The following table describes the valid values of the MetricName and Dimensions parameters.
