For a single box, ntop is what you're looking for. Be forewarned though
- traceing ALL packages (which ntop will do) takes a lot of disk-space.
Your /var will grow considerable. But the stats are very very nice!

Well, you wanted detailed graphs? I would exactly call the output pretty
but it's there, sorted all kinds of ways.

ntop takes *minutes* to load its web pages on my 1.4ghz Pentium 3 Tualatin server. I'm looking at overall processor usage and it's ~90% idle.

Web <> realtime unless you run applets of some kind. But it'll get close
enough. Otherwise, why not look for a real network management solution
like nagious? They'll give you interface traffic on all your equipment.
Usually I track traffic accross the network; not just on a single host.

nagious is way too much for what I want. I only have three hosts on the LAN side, but my server is an actual web server with thousands of views a day. I don't care about the stuff nagious presents. I only want real time, such as darkstat's real time view, throughput measurement.

I guess I'll have to make my own if there are no other ideas.
