Documentation forNetFlow Traffic Analyzer
Analyzing network traffic and bandwidth is a key capability of SolarWinds Observability Self-Hosted (formerly Hybrid Cloud Observability) and is available in the Advanced edition. NetFlow Traffic Analyzer (NTA) is also available in a standalone module.

Historical updates in SolarWinds NTA

Changing IP groups, applications, or NetFlow sources are referred to as update operations.

If you change IP Address Groups, Applications or NetFlow source settings, the changes will also be applied on historical data. The most recent data will be updated first, and then older data stored during the retention period.

As a consequence, two or more users are able to make changes affecting the same applications or IP Address Groups at the same time.

Running updates in NTA widgets

If an update is running, all relevant widgets will inform you about it. The data in the widget might be inconsistent, because historical data are being updated.

The warning message in the widget includes completion percentage. The shown percentage depends on the time settings in the widget.

For example, a widget showing the last three hours of data informs you that an update is affecting it, and that 50% is complete. If you change the time frame to the last hour, the percentage of already updated data will rise. However, if you expand the time frame to last month, the completion percentage is much lower.

You can set how often widgets should refresh when an update operation is running. Navigate to NTA Settings > Charting and Graphing Settings, select Automatically Refresh Resources Affected by Running Updates, and adjust in minutes.

About change request conflicts

NTA displays a message if you make a change that conflicts with a change by another administrator. Conflicting change requests might cause some of your changes to fail. Possible causes of conflict include:

  • Two administrators changing the same application or IP Address Group at the same time.
  • An administrator modifying an application while another administrator is changing an IP Address Group relevant for the application.

Resolve a change request conflict

  1. Review the conflict message, and submit your changes.
  2. Verify that your changes have been submitted successfully.
  3. If some changes are not submitted, repeat the changes, and submit them again.
