    This is a good idea, thanks for bringing it up.  Even using host groups 
and templating to define most of our services, we could still send passive 
results back to Nagios more frequently than Nagios triggers active checks. 
The (old) active check would serve as a sort of "freshness reaction" for a 
while.  We can later change the active check to our generic "this service 
did not check in" notification via check_dummy.


Thanks,

Ivan.
