Getting too many Nagios notifications

Hi,

I have a simple setup running Nagios 2.3.1 (actually NagiosVMA, configured using
Groundwork Monarch). I have a host with many services on it (both remote checks
performed using check_by_ssh and checks for various public services), and I get
a barrage of notifications whenever something goes wrong.

So, I defined dependencies. The services in a host are dependent on the host
(and/or on the PING service, and some other general services). But, there are
some timing issues that mean I still get hammered with a lot of alerts. What
happens during outages it this:
1. The host itself goes down, but not before a few services manage to go down
individually (so I get a few service down notifications)
2. More services that go down when the host is down do not generate any
notifications - good.
3. When the outage is over, Nagios detects the host is up.
4. Now the services are detected as going up, and since the host is up there is
no dependency to filter the notifications, so I get a whole barrage of "service
OK" notifications.

These are killing my cellphone :-). Can anyone direct me to the best way to
better configure these things?

Thanks!
