Php network weathermap works well for me. The configuration language is pretty straightforward, and it's easy to consume data from either the usual suspects (mrtg), or to write a plugin that uses a custom (sql or other) datasource.
This gets you within 60 seconds of realtime, and the price (time) is right.

Mikrotik's "The Dude" app actually does exactly what I'm looking for, but the snmp support for non-RouterOS devices seems to be lacking, as it simply won't enumerate my switch interfaces in order to capture utilization. I've downloaded several trial tools (WhatsUp, NetCure, Solarwinds LANsurveyor etc.) but they don't serve this very basic need of mine to see the realtime link util in the diagram. Thanks, Hank Disuko
