We currently use flow-tools to capture netflow data (v5) and a custom app 
written in C which utilises the flow-tools library to read the netflow file 
flow-by-flow, tally up the bytes downloaded per customer IP address (or 
subnet), and update an SQL database with the aggregate results.

I've wondering if others are doing a similar thing and how they achieve this 
using nfdump tools.

The reason I ask is that we're looking at how we can do similar accounting on 
ipv6 traffic. AFAIK netflow v9 is required, and as flow-tools doesn't support 
that, I'm thinking that nfdump may be an alternative.

Thanks,
Ian.
