With nProbe 100 (ntop's 100 Gbit flow probe) it is now possible to export flows to ntopng in order to see in realtime what happens.

Example

# cento -i zc:ethX -A

Cento will print the interfaceId to use in ntopng

07/Jan/2016 19:55:30 [MonitorInterface.cpp:43] You can now start ntopng as follows: ntopng -i zcflow:999

then you cant start ntopng as follows:

# ntopng -i zcflow:999
