[hobbit] Is there any equivalent to BB's notifications exclusions?

In that case I misunderstood the BB config semantics - which is not
surprising, since they never made much sense to me, and I haven't
used them for more than 5 years :-)

I realize that you have a working set of configuration rules, but I think
it would be a lot easier to work out a functionally identical set of
rules for Hobbit/Xymon if you could describe what it is you want to
achieve with the configuration, instead of focusing on how it was 
done in BB.

The closest to what you want to do might be to use the "IGNORE" setting in 
hobbit-alerts.cfg. E.g. your example:
   !host*;;*;;0 6;*;robert at localhost
could be accomplished with something like

   HOST=%^host TIME=06:0000:2359
        IGNORE

although this would kill alerts for all recipients, not just those destined
for "robert at localhost". And note that this must go BEFORE any of the other 
rules for this host.

I can see that the BB exclusion mechanism might be useful in some circumstances,
but it would (obviously) make the alerting mechanism more complicated.
And I'm not convinced that there's enough gained to warrant this.
