These release notes provide additional guidance for SolarWinds NetFlow Traffic Analyzer (NTA) v3.11.0.

New Features and Improvements

NTA version 3.11 includes the following new features and improvements:

  • CBQoS Nested Policy Support

    NTA now supports CBQoS nested policies. You can display class and policy trees for each direction with CBQoS resources in Interface Views, and configure Alerts and Reports for your CBQoS-enabled devices with nested policies.

  • Improved CBQoS Polling Performance

    CBQoS polling can now handle larger amounts of data, improving NTA performance. The load on SQL has been lessened thus improving the polling performance and enabling better scalability of additional pollers.

  • Sampled NetFlow Support

    NTA now supports sampled NetFlow data for devices that support selected fields. NTA automatically takes into account the sample rate set on your devices and displays ingress and egress statistics appropriately. 
    For more information about supported fields, see Sampled Flow Supported Fields in the NTA online help.

  • Flow Navigator Improvements

    NTA improved the way you can access specific endpoints very quickly. In addition to IP Address filtering, you can use the improved Endpoint filter in the Flow Navigator to filter subnets by just typing in an IP address range or using the CIDR notation. The Flow Navigator also allows you to search for CBQoS policies, both for the policies that are currently active and for policies that used to be applied in the past.

Open Issues

Issue Case Number

Lazy Upgrade Performance

If you monitor more than 50 million endpoints in NTA, the upgrade from NTA 3.9 to NTA 3.11 can take more than one day. The background synchronization of NTA tables goes on even after you finish the Configuration Wizard. This type of upgrade is called "lazy upgrade." The lazy upgrade might also result in a generally higher database load, so other performance of modules in the same environment could also be affected. When the upgrade finishes, performance returns to normal.

-

Unsupported Subviews Activation

When NTA 3.8, 3.9, 3.10, and 3.11 are used  with SolarWinds NPM, it is possible to configure NTA's Customize Page feature to show or hide SolarWinds NPM subviews that NTA does not support.
When the subview is not supported, NTA creates the new subview with the specified resources. However, if you submit the new view and return to the customized page, no left navigation exists, so the new subview is inaccessible and not usable. Users should disable the NTA Customize Page show/hide subview functionality when using the stated versions of NTA.

-

Sampled NetFlow Display Issues

Some devices treat sampled flows as non-sampled flows, such as flexible NetFlow, JFlow and NetFlow v 5. In these cases, NTA displays data scaled down by the sampling factor. 

 

-

NTA 3.8 End of Life

 NTA 3.8 has entered the End-Of-Life (EOL) cycle. This means that SolarWinds will no longer provide any form of support (such as covering call, engineering updates, etc.) for NTA version 3.8 or older. See the SolarWinds EOL Policy online for more information.
