This topic describes the metrics for Server Load Balancer (SLB).

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

  • Set the Namespace parameter to acs_slb_dashboard.
  • Set the Period parameter to an integral multiple of 60. Default value: 60. Unit: seconds.

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