Use node problem detector to detect machine check errors reported
in a cluster. When a machine check happens in a cluster it will
generate a event and report it to kubernetes
To get cluster wide status:
```
$ kubectl get events --field-selector reason="Hardware Error"
LAST SEEN TYPE REASON OBJECT MESSAGE
22m Warning Hardware Error node/clr-01 mce: [Hardware
Error]: Machine check events logged
22m Warning Hardware Error node/clr-01 Hardware event.
This is not a software error.
```
For full details on all reported events:
```
$ kubectl get events --field-selector
reason="Hardware Error" -o json
