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.

Resolve duplicate flows

If your devices are configured to export NetFlow on both ingress and egress interfaces, you might see duplicate traffic in your widgets.

Duplicate flows can occur in the following cases:

  • You have both ip flow ingress and ip flow egress applied for all interfaces on a device.
  • You have set ip flow ingress on some interfaces and ip flow egress on other interfaces.
  • On your serial interfaces with subinterfaces, you have NetFlow export enabled on both the physical and logical interfaces.

Things to check

  • If your device configuration contains both ip flow ingress and ip flow egress commands, make sure NetFlow is enabled only for ingress interfaces. Go to appropriate devices and make sure the configuration contains only the ip flow ingress command.
  • If you have NetFlow enabled for both physical and logical subinterfaces, remove the NetFlow export commands from the physical serial interfaces and only have the subinterfaces enabled for the export.
