What Is NetFlow?

NetFlow is a network protocol developed by Cisco for collecting IP traffic information and monitoring network flow. By analyzing NetFlow data, you can get a picture of network traffic flow and volume.


NetFlow is a one-way technology, so when the server responds to the initial client request, the process works in reverse and creates a new flow record. Using a NetFlow monitoring solution can allow you to monitor and analyze these flow records more efficiently and effectively for traffic within the network.


SolarWinds® NetFlow Traffic Analyzer (NTA) is a powerful and affordable NetFlow management solution with comprehensive monitoring tools designed to translate granular detail into easy-to-understand graphs and reports—helping you more clearly identify the largest resource drains your bandwidth.
