I'm working for an ISP, and we got billing system that imports netflow data, captured as files via flow-capture (from flow-tools, common unix package for netflow). Billing system have very limited capabilities for traffic analysis, so we need an instrument, well, like NetFlow Analyzer ;). So, i've got a question - can NetFlow Analyzer work with data from files, not directly came as netflow udp packets?
Actually, it's possible to "retransmit" captured data as netflow packets via flow-tools, but that's not what I'd like to see.
