# Kubernetes Node Problem Detector

This chart installs a [node-problem-detector](https://github.com/kubernetes/node-problem-detector) daemonset. This tool aims to make various node problems visible to the upstream layers in cluster management stack. It is a daemon which runs on each node, detects node problems and reports them to apiserver.

```console
|
|
$ helm install stable/node-problem-detector
