Parent-child relationships are useful to get a bigger picture of points of failure, for example if a web proxy has 5 app servers behind it, 6 hosts will go down if that proxy fails. -lee -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

You might want to looks at something like opsview if you want a picture of your network like that. Also, fwiw, I think what you're really asking for is a layer 1 map if you want to know what host is plugged into what port - layer2 would be like what host is on a particular broadcast domain. I think most people give up on the nagios map pretty quickly, or at the most setup a few partent/child hosts and leave it at that. .r' -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

If your switch can do SNMP you can monitor the switchport the trunk is connected to. -lee On Wed, Mar 11, 2009 at 11:37 AM, Victor Lee wrote: > In the course of my learning (just starting out) how to work with Nagios I > have found that it isn't aware of layer 2 connections.
