About Icinga 2

What is Icinga 2?

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

Scalable and extensible, Icinga can monitor large, complex environments across multiple locations. This includes your data center as well as your private, public, or hybrid clouds.

Icinga 2 is the monitoring server and requires Icinga Web 2 on top in your Icinga Stack. The configuration can be easily managed with either the Icinga Director, config management tools or plain text within the Icinga DSL.
