Some things don't work

"So, I would run the nagios-plugins-nrpe rpm on the remote machines (all
are CentOS 3.3, except for one FC2)?  Are there other plugins I have to
add?  What would I do to the FC2 box (there is a Dag nagios-plugins-nrpe
rpm for FC2)?  Sorry for my denseness."

 

I believe I used the dag nagios plugins rpm for FC2, I think I used that
successfully for FC3 as well, but if there's no dag rpm, just grab the
gz. 

 

Run it on all your hosts that are linux, and make sure you run the nrpe
as well, and setup /etc/nagios/nrpe.cfg with allowed_hosts listing your
nagios host.

 

Host you want to monitor - Install NRPE and Plugins.

 

Chkconfig Nrpe on. Edit Nrpe to suit your network.

 

Start nrpe service.

 

Run test check from your Nagios host maching.
