I didn't define how I wanted to implement it because that is part of
what I wanted to find out. It turned out to work relatively well.
Based on the replies I am first going to set up Cacti to get our
basic needs tended to and then set up ntop when I have the time/desire.
The tcpdump solution sounds interesting but it is too time consuming
and overkill for my purpose.
Thanks for the response.

You should define better how you want to implement this. For
instance are you going to be using SNMP (which can snarf stats from
another machine), are you going to measure the local NI on the host
itself, or are you going to actually measure packets passing a
"gate" by sniffing them? Also are you interested in historical data
or are lossy solutions like RRD OK?
There's bmon, which is a bandwidth monitor that's very simple.
Available through fink. Runs even on my Linksyshttp://
people.suug.ch/~tgr/bmon/
ntop also runs on the local host and there's even a version I have
installed on my Linksys WRT54GS.
MRTG isn't "dead" but still widely used.
Cacti is good.
And on the high end their's HP OpenView.
And if you tcpdump to a database there's no end to what you can
accomplish in terms of reporting, graphing, latency detection, ...
This last solution is what we do for an ISP. Very powerful.
