I use Nagios XI for monitoring a network of different devices. I need a flexible configuration of relations between hosts and services. For example, there is a DEV1 which I monitor and there is DEV2 which I monitor too. DEV1 depends on DEV2. When DEV2 goes down, DEV1 goes down too. However If DEV1 goes down, DEV2 mb or may not go down. Here I need send notification by the following set of rules:

DEV2 goes down -> send not. that DEV2 is down; don't send not. that DEV1 is down.

DEV1 goes down -> send not. that DEV1 is down.

And there are much more logic in my network. How I can do this with nagios, it is kind of expressions? If I cannot do this with Nagios, which program I can use to do that?

You might get better response by asking this on the wiki.nagios.com or support.nagios.com. –  mdpc Jun 1 '12 at 20:25
I don't understand. Why you don't want to get notification about DEV1 when DEV2 goes down? (while you said "When DEV2 goes down, DEV1 goes down too.") –  quanta Jun 7 '12 at 17:33
