Install Icinga 2 on Ubuntu 16.04

Icinga 2 is an open source network monitoring system which checks the availability of your network resources, notifies users of outages, and generates performance data for reporting.

Icinga 2 is scalable and extensible and it can monitor large, complex environments across multiple locations.

It supports Graphite and InfluxDB natively which thanks to a direct TCP connection, you can enjoy real-time performance graphing with little system load.

The Icinga 2 branch is constantly in development with the below design goals set:

Code quality Interoperability with external interfaces Scalability Clear-cut, object-based configuration Intelligent checks and commands & agent-based checks Dynamic notifications Business processes out of the box

In this article, we will install and configure Icinga 2 with a web interface on a Ubuntu 16.04 VPS. We assume that you have a LAMP (Apache, MySQL, PHP) stack installed on your server. This tutorial is written for Ubuntu 16.04 and it should work on other Debian-based distros too. We have another tutorial on how to install Icinga on CentOS.
