Host check notification problem

[Jack Doyle]

This may have nothing to do with your situation, but one thing I've
noticed is that if you are using "non-fixed" downtime, i.e. down for two
hours when it's first noticed as down, if it notices services down
first, it will send notifications.  It won't actually stop sending until
it determines that the host is actually down.

I don't like this side effect... it can cause you to get notifications
when you intended to have the server down.

I hope this makes sense?  My mind is a mess right now.

Actually, I don't think (memory late at night?) that you should be
getting
service notifications at all during the host downtime.   This tells me
that
your host is going down, then coming back up or going into an unknown
status.

Use the web interface, bring the host down and then find out what status
it is going into.  I suspect that it's going into an unknown status and
that's why service checks are still happening and why you're not getting
host notifications.

(configuration looks fine, fyi)
