check_nrpe giving me fits


#1

Hello,

Here is my setup:

Nagios server running OpenBSD 4.0 with Nagios version 2.5. I have the basics up and running. Now I would like to monitor several Debian servers. On the Debian server I do;:

#* apt-get search nrpe*

and I get:

nagios-nrpe-plugin - Nagios Remote Plugin Exectutor Plugin
nagios-nrpe-server - Nagios Remote Plugin Exectutor Server
nagios-plugins - Plugins for the nagios network monitoring and management system
nagios-plugins-basic - Plugins for the nagios network monitoring and management system

Which one of these do I need to monitor the Debian boxes?

I have looked around and all I can find is how to install Nagios on Debian and nothing very clear on the basic package to monitor a Debian box. I tried a few of these packages and some of the check_nrpe commands would give me back information while others would not, So I may have had too many packages installed (I think I had all of them installed at one point). So instead of trying to troubleshoot a bad install I would like to go back and install the correct packages.

I may be rolling out hundreds of Debian clients that will need monitoring including all the nrpe commands and more and I am a little lost.

Thank you for any help you can give,

I dont think you need any specific to monitor a debian box. Most of my monitoring is of Windows boxes and SNMP based. Is snmp configed on the deb box? Does the nagios box have read access?

I got the basics working by installing on the Debian server:

agios-nrpe-plugin - Nagios Remote Plugin Exectutor Plugin
nagios-nrpe-server - Nagios Remote Plugin Exectutor Server
nagios-plugins - Plugins for the nagios network monitoring and management system

After I installed these I didnt change anything on the Debian server for basic (Processes and Load) monitoring. For disk monitoring I needed to define /hda1 in the nrpe.cfg file and thats it.

The real trick was having my commands well defined on the Nagios server.
