Does anyone known of any good Linux tools for visualizing networks that change (quickly) with time.

I'm interested in things like:

  • Routes between nodes
  • Delays between nodes (especially as they change with time)
  • Throughput

I have root access to all the nodes (so I can run daemons on them all). Also, assume that I either have a management network that is stable or I will collect data and then analyze it offline.

OpenNMS runs on a LAMP stack has both manual and automatic mapping capability. I can't say it is trivial to setup up, but it's an incredibly flexible and featureful platform with a very active community. You could setup Threshold Alerts for things like latency between nodes, dropped routes, lost paths, etc.

OpenNMS Mapping

Zenmap (the GUI version the famous namp) has a nice topology mapping feature. Although, it will only generate a one time map and will not automatically update or give you threshold alerting. It will however, with five minutes worth of time, give you a quick and dirty topology map.

The best way to analyze that is imho to look at the statistic counters of the network devices involed (switches/routers).

This is called netflow analysis - there seem to be free and commercial tools around for this.
