This topic describes the metrics for clusters, nodes, and pods in Container Service for Kubernetes (ACK).
Note Before CloudMonitor can monitor ACK clusters, you must update the
metrics-server component of the clusters to V0.3.8 or later. For more information, see Install the metrics-server component.
When you call an API operation provided by CloudMonitor, set the Namespace and Period parameters.
- Set the Namespace parameter to acs_k8s.
- 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.
