Mark,
A simple (not so simple) is to setup MRTG and/or Big Brother with MRTG modules, this can/is used to monitor network interface activity and displays this as a graph, a visual representation is obviously a better to use.
I have used another tool PLOTICUS which I use to extract 'sar' CPU utilisation and convert this to a graph see http://ploticus.sourceforge.net/ (see attached)
A useful link: http://rak.isternet.sk/linux-netman/monitoring.html
Enjoy

If I have a Linux box set up as my office gateway, is there any way I
can monitor traffic so that at periods of peak usage I can see which PC
on the LAN is using which bandwidth?
The problem I'm trying to solve is when bandwidth apparently drops to
(near) zero, is it because of a problem outside the office or because
one inside? Then, if the latter, which PC is causing the problem?
Traffic graphs like shown on IPCop will help me determine the answer to
the first question but then I'm stuck.
As an alternative to all of this, if I have a Linux box on the network
(but not the gateway) can I sniff the LAN traffic to achieve the same
result?
