Depending on the versions you use, the commands and/or the path shown in this tutorial might be different.
The version of Icinga used (version 2) is referred sometimes as “Icinga” or “Icinga 2” accross the tutorial.

What is Icinga?
Installation
Icinga is made of two parts - Icinga 2 and Icinga Web 2. The first one is the core of the software and the second is a web interface.
Install Icinga 2 core
Add Icinga's repository to the package management configuration. First of all, we need to add our Icinga2 repositories to our server.
