An API server serves as a core component on the control plane of a Volcengine Kubernetes Engine (VKE) cluster. This topic describes the common metrics of the API server in the VKE cluster. To view all metrics, go to VKE monitoring metrics.

Volcengine Managed Service for Prometheus (VMP) classifies the metrics reported by VKE clusters into the following types: basic metrics, other metrics, and custom metrics. Billing methods vary based on different metric types. For more details, see Billing items.
