Provided by Prometheus, node-exporter is mainly used to collect information and running metrics of Linux-type nodes, such as the CPU, memory, load, file system, and network of the host. This topic describes the common metrics of node-exporter in the Volcengine Kubernetes Engine (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.
