inodes-monitor-plugin 0.5.1
Jenkins 2.263.1
The Nodes monitoring didn't refresh for some time (showed N/A for values) and I found this in the logs:
```

I suspect that it happened because one node was offline

added a comment - See https://github.com/jenkinsci/inodes-monitor-plugin/pull/4 which should IMO fix it.
Not sure though which value I should return in that case

added a comment - Hi kutzi
can you please help me to reproduce this issue? kutzi
added a comment - Hi there,
it's pretty long ago.
I think it was quite easy to reproduce, when one of the build agents is being restarted.
During that time you will get with some probability this error

This seems to happen whenever only a single agent is down.
Then also e.g. the REST API for any other agent is broken
