Nagios reporting no output when there is output

[Tom Wlodek]

"no output" message in nagios usually means: "Your script has an error".

Tahe the script which is supposed to execute "notify-by-email" command
and execute it by hand. It should fail and give an error msg. This will
give you a hint.

Good luck.
