SolarWinds NetFlow Traffic Analyzer

SolarWinds NetFlow Traffic Analyzer

Get a Complete Picture of Network Traffic & Bandwidth Utilisation

SolarWinds NetFlow Traffic Analyzer (NTA) enables you to capture data from continuous streams of network traffic and convert those raw numbers into easy-to-interpret charts and tables that quantify exactly how the corporate network is being used, by whom and for what purpose. And with CBQoS monitoring, you can be sure that the policies you’ve set give your mission-critical traffic the highest level of priority. NTA makes it easy to get a comprehensive view of your network traffic, find the bottlenecks, and shut down the bandwidth hogs.


  • Identifies which users, applications, and protocols are consuming the most network bandwidth and highlights the IP addresses of the top talkers on the network
  • Monitors network traffic by capturing flow data from network devices, including Cisco® NetFlow v5 or v9, Juniper® J-Flow, IPFIX, and sFlow®
  • Maps the traffic arriving from designated ports, source IPs, destination IPs, and even protocols, to application names you can easily recognize
  • Performs Class-Based Quality of Service (CBQoS) monitoring to ensure that your traffic prioritization policies are effective
  • Enables you to quickly drill-down into traffic on specific network elements, using multiple views to get the perspective you’re looking for
  • Generates network traffic reports with just a few clicks
  • Facilitates investigation of fault, performance, and configuration issues thanks to complete integration with NPM and NCM
