On the controller remote host I installed both nrpe and plugins
In the
file I can see
Code: Select all
command[check_mem]=/usr/local/nagios/libexec/custom_check_mem -n $ARG1$
But On the disk there is not file named
What am I missing on my remote host config?

You may want to do a "locate custom_check_mem" to see if it's somewhere else on the system. Otherwise, you can find the script in the linux-nrpe-agent/subcomponents/extraplugins/plugins directory of
http://assets.nagios.com/downloads/nagi ... ent.tar.gz.

Code: Select all
# locate custom_check_mem
locate: can not stat () `/var/lib/mlocate/mlocate.db': No such file or directory

I downloaded and installed both
Code: Select all
https://downloads.sourceforge.net/project/nagios/nrpe-3.x/nrpe-3.2.1.tar.gz
and
Code: Select all
https://github.com/nagios-plugins/nagios-plugins/archive/release-2.2.1.tar.gz
What is the agent ?! I never see / used before

The agent is what is installed on the client machine so the Nagios server can communicate with the client machine and run plugins found on it. Going foward and if the machines support it, I would recommend following the steps in
https://support.nagios.com/kb/article/n ... rpe-8.html which should install the agent and plugins in one step.
