Configure data retention for flows on unmonitored ports

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.

If you see a significant percentage of unmonitored traffic in your Top XX Application resource, expand the tree and drill down to the interface level. Click Monitor Port in the Orion Web Console to track this traffic by port.

Enabling this option may significantly increase the processing load on both your SolarWinds NTA server and your Orion database server. Clear the Allow monitoring of flows from unmonitored ports option to save space in your database and discard data from unmonitored ports.

  1. Click Settings > All Settings.
  2. Under Product Specific Settings, click NTA Settings.
  3. Select Allow monitoring of flows from unmonitored ports.
  4. Click Save.
