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.

[Nagios-users] Layer 2 connectivity awareness?
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. In other words, if I have 2 switches with a trunk between them Nagios doesn't seem to provide me a way to either note that manually on the map nor does it seem to be aware of that type of connectivity. The same applies to servers, there doesn't seem to be a way to identify which switch a server is connected to. Now I admit this might be due to my limited knowledge of the product so I ask the members here.
