Right, which is what I did. However, the docs with NRPE did not specify
that the check_* scripts needed to be on the remote host as well. I had
to figure that out. The Nagios FAQ page is good for most debugging but I
think it ignores this fact.
And yes, it is an easy matter to simply tar all the scripts up and place
them on whatever box you want. I am simply partial to the bblient script
included with Big Brother. It's fairly automated.

Right. Again, it sounded like the entire Nagios program had to be
installed, but if you only need the plugins, then couldn't you just
simply create a /usr/local/nagios/libexec directory and run them there?
Otherwise, I like Nagios and am working to migrate all the monitoring to
it specifically. I would just like to reduce the amount of time involved
in getting the clients set up.
Thanks.
