You did it the hard way.

Rather than attempt to solve your problem directly, I urge you to solve this
the easy way, with the 'parents' directive:

HTH.

> I am monitoring a network of several hosts, switches and

> not receive pages on downstream hosts when a dependent 
> upstream host is down or unreachable.  The problem I am 
> encountering is when the upstream node (closest to the Nagios server)
> goes down, I do not receive notifications for any hosts 
> dependent on that upstream device (as expected) ... but when 
> the upstream host becomes reachable/up, I receive UP 
> notifications for all hosts dependent on the upstream that 
> went into a HARD down/unreachable state.  According to the
> "notification logic" documentation, an UP notification should 
> never be sent on a device that did not trigger a 
> DOWN/UNREACHABLE notification.
> 
> Can anyone explain this behavior and possibly instruct me on 
> what needs to be done to suppress the UP notifications for 
> all of the dependent devices?
