Well, the web interface only really displays the results of checks that
have been configured; you can't specify a custom check through the web.

Is it in your checkcommands.cfg? If not, you need to add it, then add
the appropriate entry in services.cfg. Adding an entry to
checkcommands.cfg is usually pretty easy--all you need is a made-up
command_name and the correct command_line. Since you seem to have a
command line that works, I'd suggest adjusting that to a
checkcommands.cfg entry.

You don't need to write the plugin (not if it already works through the
command line!), but you do need to add the right entry to checkcommands.cfg.
Otherwise you can't add it to services.cfg, nagios won't monitor it, and
the web interface can't show you the results of what nagios isn't
monitoring. It's not trivial, but it's not difficult, either.

If you have further trouble, you should post back to this thread with
more details.
