This is almost, but not quite, what I do. Specifically, I use fprobe to generate flows, and then nfsen/nfdump to generate the pretty pictures that management seems to enjoy so much. nfsen can be configured to generate some of the information that you want, but you can write your own perl scripts to parse the raw nfdump files and extract whatever information you want.
