This should help you with configuring your Nagios server. I would recommend reading the following section to start with as it would show you how to define various objects in Nagios Core:
https://assets.nagios.com/downloads/nag ... tions.html
2. NRPE Documentation
https://assets.nagios.com/downloads/nag ... e/NRPE.pdf
Since you are using NRPE, it would be beneficial to review this entire document.
I will be closing this topic now. If you have any further questions/issues, please start a new thread. Thank you!
