NTA 4.6 offers new features and improvements compared to previous releases of NTA.

Local NetFlow Source

The Local NetFlow Source in SolarWinds NetFlow Traffic Analyzer (NTA) presents real flow data. It allows you to use all standard SolarWinds NTA features, such as navigation, drill-down, filters, reporting, and more, without any prior configuration and discovery.

The Local NetFlow Source provides basic insight into the traffic on the Main Polling Engine. All traffic for any network interface on the Main Polling Engine is captured and transformed into NetFlow flows. SolarWinds NTA then visualizes these flows as if they were exported by the Local NetFlow Source. Flows exported by a Local NetFlow Source behave the same as flows from real devices.

SolarWinds NTA in Microsoft Azure

For fresh installations, you can deploy the Main NTA server onto a Microsoft Azure VM and the NTA SQL Flow Storage database onto Azure SQL. In an existing Orion environment, you can migrate the deployment from on-premise to Azure or from Azure to on-premise.
