Restart service problem with sudo

[Andy Shellam]

In your Nagios event handler definition, add the following after it:

 > /tmp/debug.log 2>&1

(e.g. /etc/init.d/mysql restart > /tmp/debug.log 2>&1)

Then examine the file after nagios has run the event handler.
What that should do is output any info and errors returned from the 
command to debug.log in /tmp.

I'm guessing it's going to be something like an environment variable 
that isn't set when Nagios is running, but is when cron (or yourself) 
runs it.
Possibly $PATH?

Anyway try the above, and let us know what you get.
Failing that post your /etc/init.d/mysql script and /tmp/debug.log (as 
attachments) and we can investigate what variables that script needs set.
