Most people use nProbe and ntopng to collect flows using an architecture similar to the one below where nprobe and ntopng are started as follows: nprobe -3 <collector port> -i none -n none —zmq “tcp://*:1234” –zmq-encryption-key <pub key> ntopng -i tcp://nprobe_host:1234 –zmq-encryption-key <pub key> In this case ntopng communicates with nProbe over an encrypted channel […]
What is Score, and How It can Drive You Towards Network Issues
Telemetry protocols such as sFlow/NetFlow, SNMP or packet-based traffic analysis are the source of data for network traffic monitoring.
