Nagios Support Forum

Initially when I started NRPE to monitor remote host, I ran into some configuration issues. So I decided to clear previous installation/configurations and start a fresh one. But, a doubt came to my mind whether NRPE may be required on Nagios Core server in order to monitor remote serves. That's why I asked the NRPE installation on Nagios Core server.

My goal is to monitor Nagios Core server and other Linux remote servers.

Please advise.

Thank you,

From page 2 of the NRPE documentation:

The NRPE addon consists of two pieces:
•The check_nrpe plugin, which resides on the local monitoring machine
•The NRPE daemon, which runs on the remote Linux/Unix machine

Further down:

Note:
The NRPE daemon requires that Nagios plugins be installed on the remote Linux/Unix host. Without these, the daemon wouldn't be able to monitor anything.

You don't need NRPE to run checks against the host. Just run the normal nagios plugins (or 3rd party plugins).

Does that all make sense?
