As we know Nagios is extremely popular open source network monitoring system. It watches hosts across the local area network (LAN) and/or across the Internet, services that you can specify, alerting you when things go bad. The following step-by-step guide written by Novel people (actually by Rainer Brunold) for sure would help if you plan to deploy Nagios monitoring system with Novel SUSE Linux. At least it helped me 🙂
I don’t want to write here a full documentation about Nagios, I prefer to give you a basic installation guide so you can set it up very easy and play with it yourself. The installation guide will show you how to install Nagios as well as some interesting extensions and how they integrate into each other. During this installation you will make many modifications to the installation that will help to understand how it works, how you can integrate systems and different services. I will also provide some articles about monitoring special services where I describe what they do and what configuration changes are needed. All together should give you a very good overview and documentation on how you can enhance the Nagios installation yourself.
