[Nagiosplug-devel] Custom Plugin issue

[Subhendu Ghosh]

This is the correct forum - but you may want to subscribe before posting 
as well.

Documentation on writing plugins:
http://nagiosplug.sourceforge.net/developer-guidelines.html

Nagios looks at the exit codes.
An "echo $?" after running the plugin on the command line will tell you if 
you are exiting with the proper code or not.
You are missing a "exit ($status)" line at the end.
