If your CMTS supports it netflow can do what you want:
the process is simple you turn on netflow, configure it to export the information to a server and then view the info on the server. See your CMTS manufacturer docs for how to do this
vendors such as solarwinds and manageengine have servers to facilitate your needs. http://www.manageengine.com/products/netflow/ is one that has a free version that supports up to 2 interfaces (i.e. Cable Blade or Bundle basically one or two CMTSes) forever.
depending on your traffic you may need a very robust server as it can be a ton of information
I used netflow for 9000 customers and the servers barely notices. Remember netflow only sends the statical aggregated data of your TCP/IP transactions.
I actually wrote code to process netflow and have the Internet usage of my customers in a database backend. In my opinion it is vital to have this data to manage an Internet business.
You may want to look into Ntop. I believe there is a way to process flows from devices without netflow by simply hanging a collector off the device via a hub. Been a while since I've looked into it, but it may be the ticket.

Netflow not supported for BSR2K
Hi Group
I have a BSR2K Motorola and I've been looking in docs about netflow and it seems is not supported. For this device is there another feature?
Thanks in advanced
