Review: Icinga enterprise-grade, open-source network monitoring that scales


Continuing our quest for robust, enterprise-grade open source network monitoring, we tested Icinga Core 2 (version 2.8.1) and the stand-alone Icinga Web 2 interface. Created in 2009 as a fork of the Nagios network monitoring tool, Icinga has come a long way.

We found Icinga to be a powerful monitoring tool with many great features. The Core install is straightforward and basic monitoring is easy with either pre-configured templates or plugins. However, we discovered that the Web install is a bit more complicated and could stand to be streamlined.

Icinga runs on most of the popular Linux distros and the vendor provides detailed installation instructions for Ubuntu, Debian, Red Hat (including CentOS and Fedora) and SUSE/SLES. Icinga does not publish specific hardware requirements, but our installation ran well on a quad-core processor with 4 GB RAM and this is probably be a good starting point for a basic installation.

As with most monitoring applications, storage is an important variable that largely depends on the number of hosts and services monitored and how often information is written to the log. With too little storage, the logs can easily fill up and freeze the system.
