SolarWinds NetFlow Traffic Analyzer
SolarWinds NetFlow Traffic Analyzer monitors traffic patterns and bandwidth usage across hybrid and distributed networks.
What SolarWinds NetFlow Traffic Analyzer is
SolarWinds NetFlow Traffic Analyzer monitors traffic patterns and bandwidth usage across hybrid and distributed networks. It lets teams inspect traffic by application, protocol, endpoint, conversation, and IP address group, and identify top talkers and bandwidth-heavy applications or endpoints. Color-coded graphs, charts, and filters help narrow traffic views, while drill-down screens and historical flow data support investigation of congestion and unexpected usage. The analyzer collects Cisco NetFlow v5 and v9, NBAR2, Juniper J-Flow, sFlow, IPFIX, and Huawei NetStream. Flow Navigator creates personalized traffic views and reports, with scheduled weekly delivery available. Network devices must export compatible flow data to the NTA collector, and both devices and exporting interfaces must be monitored through SolarWinds Network Performance Monitor. NTA listens on UDP port 2055 by default; other collection ports can be configured. It is described as a key feature of SolarWinds Observability Self-Hosted, which runs behind the firewall. SolarWinds offers a fully functional 30-day free trial. The product is paid, with pricing available by custom quote from Sales.
