The only empty fields are ASNs :) I hope to fill them in future.

I usually call node "netflow" using 'ngctl name', and then call 'flowctl netflow show'.

This is working solution, but not correct. :) To catch both directions you should feed ng_netflow with incoming traffic from all interfaces.
using 'tee' means you are duplicating all packets.
shouldn't you do collection "inline? or does this NEED to have copies of the packets?
