Nerd alert: Home server with Nagios, Pushover and Blink(1) warnings

I had some time for tuning my home server setup this weekend and this led to me now having Nagios-monitoring of my virtualized home servers.

Note that I have set up scripts for monitoring my son's Minecraft server and our MythTV backend server.
But not only that!!
I have the Nagios server pushing warning/failure/recovery messages through the Pushover-service to my Smartphone.
And I have also set up a script that will switch the colour of a ThingM Blink(1) USB Led that is plugged in the physical machine based on what the Nagiso status page shows.
Here everything is OK - green.
