Hello.
I've set up this system. It sort of works, but I'm no quite sure. Can you elaborate on these issues:

1. When should I expect the PROBLEM alert, and when will the trigger flip back into OK state?
2. The readme speaks of "auto-generated" triggers (some of which should be disabled). There's only one trigger. Could you please explain?
3. Is it really fool-proof? What happens if, say, bconsole times out (or any other issue occurs)? Shall I still get the alert?

It worked fine for me few years ago. Since that time I didn't work with bacula/bareos, and I accepted patch from one guy without testing it. I'll check it, when I have some free time.
