New features and improvements in NTA 4.6
NTA 4.6 offers new features and improvements compared to previous releases of NTA.
IPv6 support
As of version 4.6, SolarWinds NetFlow Traffic Analyzer listens for packets on IPv6 addresses. NTA is also able to extract IPv6 traffic details from Protocol Data Units (PDUs), including storing and displaying IPv6 addresses in reports and NTA-specific resources.
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
As of version 4.6, you can install SolarWinds NTA onto 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.
Palo Alto Conversations for the NCM Policy Detail page
Starting with version 4.6, NTA extends visibility of the NCM Palo Alto Security Policy Details page with NTA conversation traffic, showing relevant traffic for a selected security policy.
