Oh, you are right, I didn't make it explicit: my humble opinion is that the whole thread is not particularly interesting or useful in this context, since all this fuss about monitoring/supervision boils down to two alternative options: a) you *really* need *strict* monitoring/supervsion. In this case, you *don't* use a unix-like operating system, since you are always left at least with the problem of monitoring the monitor (or supervising the supervisor). But this is not a real problem, since in those environments where *strict* supervision/monitoring is *really* necessary, unix-like systems are rarely used, if ever, and the scheduler also acts as a monitor/supervisor. So if you need *real* *strict* monitoring, the whole topic is off-topic here. b) you need *loose* monitoring/supervision. In this case, you pick and choose among what is available, or write your own. In any case, you get a monitor/supervisor running as a user process on top of any general-purpose operating system, possibly a unix-like one, and your applications must still be able to deal with faults, inconsistencies, delays, and other issues. And sometimes you will still need manual intervention nonetheless. The "everything will be all right" theme is just dust in your eyes, because things are never going to be all right all the time. There is really no other reasonable alternative, IMVHO. But I am not an expert in the field (though I am quite happy about not being an expert, having seen what the "experts in the field" have been able to come up with in the last couple of years...)
