Parents vs Dependencies ?

[John Lange]

I am monitoring a collection of servers using nagios. The nagios machine
is my desktop computer in my office and the link to the outside world is
a cable modem.

Nagois works fantastic and I'm thrilled with it.

The only issue is that occasionally the cable modem link will go down
and this results in a lot of false notices being queued up on my desktop
machine and then when the link returns a get a flood of pages.

My understanding is that nagios has a way to prevent this either using
the parents setting or the dependencies.

Currently I have the cable companies router with check_ping set as the
parent for all of my servers and I have it's host settings so that I
don't receive notifications for that router. The theory being that if
the router can't be reached then the cable modem is down and I don't
want any notices to be sent out. The documentation mentions that nagios
"walks" the parents before sending out notices but is rather vague on
exactly how to make this work.

My guess is that this is documented someplace but after a fair amount of
googling and reading the nagios web site I don't seem to be able find
any examples.

Can someone help me out and point me in the right direction?

Is setting up parents with no notification all I need or is there
something more?
