# node-problem-detector
node-problem-detector aims to make various node problems visible to the upstream
layers in cluster management stack. It is a [DaemonSet](http://kubernetes.io/docs/admin/daemons/)
detecting node problems and reporting them to apiserver. Now it is running as
a [Kubernetes Addon](https://github.com/kubernetes/kubernetes/tree/master/cluster/addons)
layers in cluster management stack.
It is a daemon runs on each node, detects node
problems and reports them to apiserver.
node-problem-detector can either run as a
[DaemonSet](http://kubernetes.io/docs/admin/daemons/) or run standalone.
Now it is running as a
[Kubernetes Addon](https://github.com/kubernetes/kubernetes/tree/master/cluster/addons)
enabled by default in the GCE cluster.

connects the apiserver. The format is the same with the

* If needed, you can use [ConfigMap](http://kubernetes.io/docs/user-guide/configmap/)
to overwrite the `config/`.
## Start Standalone
To run node-problem-detector standalone, you should set `inClusterConfig` to `false` and
teach node-problem-detector how to access apiserver with `apiserver-override`.
To run node-problem-detector standalone with an insecure apiserver connection:
```
node-problem-detector -apiserver-override=http://APISERVER_IP:APISERVER_INSECURE_PORT?inClusterConfig=false
```
