Feature request: netflow statistics processing

[z-eos]

it'd be nice to be able to draw netflow data

for example it is easy to collect it with softflowd + flow-tools

data collected, then, can be printed out in custom formats

default format (with header) is

#
# mode:                 normal
# capture hostname:     bbox
# capture start:        Tue, 03 Nov 2020 00:35:01 +0200
# capture end:          Tue, 03 Nov 2020 00:40:00 +0200
# capture period:       299 seconds
# compress:             on
# byte order:           little
# stream version:       3
# export version:       5
# lost flows:           0
# corrupt packets:      0
# sequencer resets:     0
# capture flows:        721

such a processing can easyly draw octets/packets for any ip in network
