The OpenNMS monitoring system has the ability to automatically discover and display links between nodes and networking equipment. The module is called linkd and is a very handy way of visualizing system layout and tracking switchports and interfaces (e.g. you can see what's connected to a switch and vice-versa).

I'm curious if any of the other monitoring packages out there offer similar functionality, or is the concept of linkd unique to OpenNMS?

Off the top of my head, SolarWinds' User Device Tracker is somewhat similar, and should plug into their Orion NPM product.

I'm not sure it is what you want, but take a look at NACE or netdot. It can create Nagios configuration for monitoring hosts. I also see that the GroundWork Enterprise edition provide topology discovery feature.
