Kubernetes is a robust system, but maintaining its health is crucial for consistent performance. Node Problem Detector (NPD), a Kubernetes add-on, is designed to identify and address node-level issues like kernel errors, filesystem corruption, or resource exhaustion. This guide walks you through the step-by-step process of setting up NPD in your Kubernetes cluster.
What Is Node Problem Detector?
Node Problem Detector (NPD) is a DaemonSet that runs on every node in a Kubernetes cluster to monitor system health. It integrates with Kubernetes to report issues as Node Conditions, Events, or Metrics, enabling early detection and resolution of potential problems.
