    Thanks very much, that helped!  I have been frustrated for a while
trying to figure this out.  I was not aware that the nagios -v check
actually identified your problem.  That is a huge help.

    So each 3rd party plugin you choose to use must be defined in the
command.cfg to operate properly?  I assume that all the standard nagios
plugins are already defined?  

    Thanks again for you assistance!

Van
