Icinga Busylight Agent is - how unsual - an Icinga2 notification agent for Plenom Kuando Busylights. It will connect to your Icinga2 instance and check for host and service events. Faulty hosts and services will generate audible and visible events - you can configure colors and ringtones.
Currently, the software is at a very early stage. Some features are missing, see the issues tab for bugs and upcoming functions.
