Install the watchdog daemon on raspberry pi raspbian
$ sudo -s # rpi-update
install the watchdog deamon
# apt-get install watchdog
load the watchdog module
# modprobe bcm2708_wdog # echo "bcm2708_wdog" >> /etc/modules
set /etc/watchdog.conf ...
this is what I ended up enabling
# cat /etc/watchdog.conf |egrep -v "^#.*" max-load-1 = 24 max-load-5 = 18 max-load-15 = 12 watchdog-device = /dev/watchdog realtime = yes priority = 1I just need to watch for system hangs ... the ping and the user commands seem nice though.
# shutdown -r now
