You might be interested in CoffeeSaint: an application that shows the status of Nagios (version 1 up to 3 and the newer XI) on a screen. It can, if there are no errors, display a Webcam feed. If an error status occurs, it can play a sound. One can configure it to display certain errors/warnings always on top. It is remotely configurable via a built-in Web interface.
If you're interested in the Nagios monitoring software or the Nagios Incident Manager, please follow this link to the Nagios website: it pays the hosting costs for vanheusden.com. Thanks!
