I'm setting up QoS on my router and I'd like to shape the most active
used ports. Is there built into OSX (I'm on 10.5.1) an easy way to keep
a record of what ports are used and how frequently/how much over a set
time period? Or a nice third part app? It will not be used often so I'm
not sure I want to pay, though that's not totally out of the question.

Regards,

Does netstat provide the data you need?

I'm not sure I'd call it easy, but I'd let tcpdump run for the
time period needed, then feed the results into a perl program
to count how many times each port is used. To get fancier,
you could also have it find min, max, avg, total, etc. of
packet sizes for each port.
