core-dns serves as the Domain Name System (DNS) server for the Volcengine Kubernetes Engine (VKE) cluster, which provides service discovery and DNS resolution services in the cluster. This topic describes the common query metrics of core-dns. To view all metrics, go to VKE monitoring metrics.

Volcengine Managed Service for Prometheus (VMP) classifies the metrics reported by Volcengine Kubernetes Engine (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.
