This topic describes the metrics for clusters, nodes, namespaces, applications, and pods in Container Service for Kubernetes (ACK).
When you call an API operation provided by Cloud Monitor, you may need to set the Namespace and Period parameters. Set the parameters for the current service in the following way:
- 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 for the current service.
