New features and improvements in NTA 2019.4

Return to top

NTA 2019.4 offers the following new features and improvements compared to previous releases of NTA.

Process flow data from Meraki MX devices

As of version 2019.4, SolarWinds NTA supports processing of flow data from Meraki MX 15.13 and earlier. The data are associated with SNMP-managed interfaces from NPM. Certain devices use different Interface IDs when polled by SNMP and different Interface IDs in NetFlow. Due to this discrepancy, traffic cannot be correctly bound to the interface. This issue is solved by mapping between Flow Interface ID and SNMP Interface ID. When you add a Meraki device to SolarWinds NPM, and configure it to export flows to the Main or Additional Polling Engine, the mapping is generated automatically when NTA receives first flow traffic from the Meraki device.

Flow Sources Management and CBQoS Polling Management pages

Starting with NTA 2019.4, you can manage your flow sources and CBQoS polling using the new management pages within the Orion Web Console. You now have a lightweight way to browse and manage your sources.
