Configure data retention for flows on unmonitored ports

Table of contents
No headers

By default, SolarWinds NTA retains all flow data provided by NetFlow sources on your network, including flow data for ports that you are not actively monitoring.

A benefit of having this data is that, should you see a significant percentage of unmonitored traffic in your Top XX Application resource, you can expand the tree to drill down into the interface level. Click Monitor Port to track this traffic by port.

However, if you want to save space in your database by disabling this automatic feature and discard data from unmonitored ports, clear Enable Data Retention for Traffic on Unmonitored Ports.

For more information about unmonitored ports in SolarWinds NTA, see Enable flow monitoring from unmanageable interfaces.

Enabling this option may significantly increase the processing load on both your SolarWinds NTA server and your SolarWinds Orion database server.

  1. Click Settings > All Settings.
  2. Under Product Specific Settings, click NTA Settings.
  3. Select Enable Data Retention for Traffic on Unmonitored Ports.
  4. Click Save.
