Kubernetes Control Plane Monitoring Overview

A Kubernetes cluster consists of worker machines that are divided into worker nodes and control plane nodes. Worker nodes host your pods and the applications within them, whereas the control plane node manages the worker nodes and the Pods in the cluster. The Control Plane is an orchestration layer that exposes the API and interfaces to define, deploy, and manage the lifecycle of containers. For more information, see Kubernetes Components from Kubernetes documentation. 

The Kubernetes Control Plane components consist of the following:

• Scheduler
• API Server
• Etcd 
• Controller Manager
