Project Description
Icinga 2 is an open source monitoring system which checks the availability of your network resources, notifies users of outages, and generates performance data for reporting.
Scalable and extensible, Icinga 2 can monitor large, complex environments across multiple locations.
Icinga 2 as monitoring core works best with Icinga Web 2 as web interface.
