Originally developed by Cisco, NetFlow is a network protocol designed to collect and monitor network traffic flow data. It has become the industry standard (alongside similar technologies like J-Flow, sFlow, and IPFIX) for network traffic analysis.
Packet capture (PCAP) is often the go-to solution, but capturing every packet on a modern enterprise network is like trying to drink from a firehose. It requires massive storage and immense processing power. netflow traffic analysis

Users complain that "the internet is slow." Is it the ISP? Is it the server? Or is it the internal LAN? Originally developed by Cisco
To understand NetFlow, you must distinguish between traffic and Control Plane metadata:
dst_asn IN (15169, 16509, 8075) AND bytes_out > 1000000000
