Icinga

Icinga is an open-source computer system and network monitoring application. It was created as a fork of the Nagios system monitoring application in 2009 in an attempt to improve on Nagios' development process. The first stable version, 1.0, was released in December 2009. In 2010 it was described as offering better database connectors, web interface, and API than Nagios. In 2012, development of a new core component was started and released in 2014 as Icinga 2 to allow for profound architectural changes compared to the Nagios core. In May 2009, a group of developers from the Nagios community announced the fork Icinga, citing their dissatisfaction with the stagnant development of the Nagios software at the time and their desire to open its development to a broader base. The name Icinga is a Zulu word meaning "it looks for", "it browses" or "it examines" and is pronounced with a click consonant. In their first year, Icinga developers released separate versions of Core, API, and Web, and celebrated their 10,000th download. In its second year, the Icinga project released unified and stable Core and Web; added dual-stack IPv6 and IPv4 support, optimized database connectivity, and revamped the Icinga Web user interface, integrating various community add-ons (PNP4Nagios, LConf, Heatmap and Business Process Addon). The project achieved more than 70,000 downloads and grew to 23 team members.
