No output returned from plug-in

Ok, I was able to fix the problem in the following way:

I removed mysql and nagios from the server and reinstalled those
packages again. Previously the drive had filled up, which did some nasty
things to mysql it seems, and when I fixed that problem, something had
become corrupted that wasn't readily visible. I suspect that it was
something in mysql that was the issue here. The reinstall fixed the
issue and everything is working fine now.

Thank you for the suggestions and help

Try su'ing your nagios user and run the command manually. If it works,
it's permissions within the web interface.

There are probably differences between the environment you get under
sudo and the one you get when Nagios runs the check, or nrpe may be
timing out.
