Throughout the years I have installed a bunch of Icinga + Adagios installations. Now, I know that Icinga2 with their own Web Configurator is out there, but Icinga is still a rock solid Nagios solution with tons of scripts ready to be used. In combination with Adagios for the configuration part, it’s hard to find a competitive free alternative.

I have kept the following guide for my self just as a quick installation guide, but finally thought it would be nice to share it with the community. Now, it’s not a bullet proof guide and you need to know the basics of Linux and troubleshooting. But I hope it can be a great help to put it all together.

The guide is tested on Debian 8 and the corresponding Ubuntu systems. It will not work on Debian 9 – already tried that.

apt-get install python-software-properties
