Nagstamon is a Nagios status monitor for the desktop. It connects to multiple Nagios, Opsview and Centreon monitoring servers and resides in systray or as a floating statusbar at the desktop showing a brief summary of critical, warning, unknown, unreachable and down hosts and services and pops up a detailed status overview when moving the mouse pointer over it. Connecting to displayed hosts and services is easily established by context menu via SSH, RDP and VNC. Users can be notified by sound. Hosts and Services can be filtered by category and regular expressions.

To find out if your Microsoft cluster did a failover is a boring task to go in the eventviewer or logs. Well I wrote a script that does just that
all it needs is check_nt NC_NET plugin on the server and nagios.
I tested with Windows Server 2008 and 2003 and NC_NET 4.x
Hope its helpfull for everyone.
