Configure data retention for flows on unmonitored ports
By default, 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 widget, expand the tree and drill down to the interface level. Click Monitor Port in the SolarWinds Platform Web Console to track this traffic by port.
Enabling this option may significantly increase the processing load on both your NTA server and your SolarWinds Platform database server. Clear the Allow monitoring of flows from unmonitored ports option to save space in your database and discard data from unmonitored ports.
- In the SolarWinds Platform Web Console, click Settings > All Settings.
- Under Product Specific Settings, click NTA Settings.
- Select Allow monitoring of flows from unmonitored ports.
- Click Save.
