Overview
The Kubernetes metrics server, also referred to as "metrics-server" is a lightweight, short-term, in-memory server to collect and expose resource metrics. metrics-server is used as part of the Kubernetes resource metrics pipeline. The metrics server discovers all nodes on the cluster and queries each node's kubelet for resource metrics (CPU and memory). There's embedded logic in the kubelet, known as cAdvisor, that
