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.
