It's pretty easy...

- create your script to perform the check. Pay particular attention to the Output and Return Code requirements of http://nagiosplug.sourceforge.net/developer-guidelines.html
- create a command{} definition that calls your script.
- create one or more service definitions that reference your new command{} definition
- reload nagios
- ...
- PROFIT!

Seems straightforward to me. Accept a command line argument referencing what you want to look for and search the output for that status. Print out the status and exit with a corresponding exit code.

Look at pretty much any of the plugins at http://exchange.nagios.org. I'd bet that the majority of them call some external program, parse it's output and return results.
