I see... you obviously know what to do, if you want to :) But I'm not sure such a device alone is of much help in a typical server. I think it's probably just as common that only one service hangs. To make it useful, the trigger process has to be carefully designed, so that it actually has a chance of failing when you need it to fail. This probably requires either code changes to the various services (so that they each trigger their own watchdog) or some supervisor program that only triggers the watchdog if it receives responses from all relevant services.
