![]() In the language of a data network environment, they monitor IP addresses, data volumes, time, ports, protocols and this can further be enriched with latency measurements and application layer data for a variety of protocols.Ĭollecting NetFlow. Network and Security Operations gain an understanding of who communicates with whom, when, how long and how often. These statistics represent the flow data in the network, which can be thought of as similar to a list of telephone calls. ![]() Network traffic monitoring generates statistics both on the underlying data transfers when abstracting from packets, and the subject of the communication itself (the content of the communication is not stored). To support a demand to extract wider data set, independent IPFIX format has emerged among a variety of proprietary formats such as jFlow, sFlow or NetStream. The most commonly used format is NetFlow v5. ![]() ![]() NetFlow enabled switches or routers, so-called exporters, generate these aggregated traffic statistics that provide a picture of bandwidth utilisation, communication partners and clients activity. NetFlow is a network standard originally developed by Cisco for collecting IP traffic information and monitoring of network telemetry data.
