If you have not setup the Nagios Server have a look at that link to setup the Nagios server.
Nagios Remote Plugin Executor (NRPE) allows you to remotely execute Nagios plugins on other linux systems. This allows you to monitor remote machine metrics (disk usage, CPU, local listening services, etc.).
NRPE has 2 sections:
- The nagios server side.
- The client side.
For nagios to execute remote plugins, the client configuration needs to allow the nrpe server which will be nagios.
