Monitor RaspBerry Pi with Nagios

Introduction

Over the past week, I had multiple questions how to monitor RaspBerry Pi with Nagios. Monitoring is crucial to pro-actively ¬†find out any issues that might come up. There are multiple ways to achieve this. I’ll try to build up this ‘how to’ from the ground, starting with using the standard traditional method, which is using the official Nagios NRPE Agent.

NSClient++ does not yet support Raspbian for now. Michael Medin told me in this forum thread that he is planning to port it once he finds some spare time.

It’s also possible to install Go and Telegraf on your Raspbian, but I haven’t got the time to test that.¬†

How to Monitor RaspBerry Pi with NRPE Agent?

The code below worked fine for me on Raspbian Jessie

Create nrpe.cfg in /usr/local/nagios/etc

The relevant part of my nrpe.cfg looks like this:

make sure to replace <ip-of-your-Nagios-server-here> with (you never guess) the ip of your Nagios server.

Let me know if you experience any issues.

Grtz
