Sorry, I didn't use complete thoughts or terminology. I did
start the daemon. When you start it, it takes the timeout in seconds
and the sleep between pokes in seconds. So I have it "nap" for 15
seconds, and poke the timer. Technically if it "misses" 8 pokes, it
should reboot. It ran for about 10 hours and rebooted on me. I had
a screen running on it that showed it was operational to within 5
seconds of when it rebooted.
So yes, the daemon is running, and because I use the
command line options :
watchdogd [-d] [-e cmd] [-I file] [-s sleep] [-t timeout]
Like :
watchdogd -s 15 -t 120
it should be operating correctly. But about 10 hours in,
it seems the system was still operational within 5 seconds of
the time it rebooted. I've now changed it to :
watchdogd -s 120 -t 1200
and will see if it "misfires".
