Monitor traffic volume on a Cisco ASA by IP address?

Question

Is there a way to monitor and report on traffic volume over a month (total transfer) by IP address? I see the traffic reports that monitor by interface, but that includes internal server to server traffic. I want to monitor the volume of traffic that goes in and out the public Internet similar to most hosting providers. Is that in NPM or would I need NetFlow? Thanks.

That's what I was worried about. Was hoping I could get it done without the additional module. Thanks for the quick response!

Netflow.  And if you use a proxy server, it will need to be passive.  Otherwise you will need reporting software for the proxy.
