Icinga is an open-source network monitoring system created in 2009 as a fork of Nagios. The project was started by a group of Nagios community developers who cited slow development, limited community input, and insufficient handling of contributed patches as reasons for the fork. The name is a Zulu word meaning "it looks for" or "it examines."
Icinga 1.x maintained compatibility with Nagios plugins and configuration files, adding a modern web interface, additional database backends (PostgreSQL, Oracle), and a REST API. Icinga 2, released in June 2014, was a ground-up rewrite in C++ with a new configuration language, a built-in cluster stack for distributed monitoring, and an API-first design.
