Given what he's doing, passive monitoring is a good idea to get around
scalability problems anyway.  But with passive monitoring he has the
added advantage that if any of the passive monitors submit a good check
result then his master nagios will say things are working correctly.  Only
if NONE of the slave monitors submit a passive check result of OK and he
doesn't have staleness checking will things go wrong. 

For the pedants, if one of the remote monitors says things are good and
another says things are bad then you're going to see flapping.  There IS
a problem but it's not where Nagios says it is.  If you want perfect
results then you'll have to hire many perfect human beings to monitor
each server.  If you want "something, somewhere is borked, and perhaps
you'll need somebody smarter than the average point-and-click monkey
to figure out where" then Nagios is adequate.  If you want perfection then
bge prepared to pay the cost.
