Documentation forNetFlow Traffic Analyzer
Analyzing network traffic and bandwidth is a key capability of Hybrid Cloud Observability Advanced and is also available in a standalone module, NetFlow Traffic Analyzer (NTA). Hybrid Cloud Observability Advanced and NTA are built on the self-hosted SolarWinds Platform.

NetFlow collector services

NetFlow Collector Services provide status information about current flow collectors. In case your flow-enabled device configuration requires it, the following procedure resets or adds flow collection ports on which the NTA collector listens for flow data. You can also delete a collector, if necessary.

If you are employing a firewall on your NetFlow collector, all ports on which the NetFlow collector listens for flow data should be listed as firewall exceptions for UDP communications.

By default, NTA listens for flow data on port 2055, but some flow-enabled devices, including some Nortel IPFIX-enabled devices, send flow data on port 9995. For more information about requirements for IPFIX-enabled devices, see Flow Requirements.

Access the management page

  1. In the SolarWinds Platform Web Console, click Settings > All Settings.
  2. Under Product Specific Settings, click NTA Settings.
  3. Click NetFlow Collector Services.

Add or reset a collection port

  1. Type the new port number in the Collection Port(s) field of the collector that you want to edit.
    • Separate listed ports with a single comma, as in 2055,9995.
    • A colored icon displays your collector status. Green indicates that the collector can receive flow data, and red indicates that it cannot. Server Name provides the network identification of your collector, and Receiver Status is a verbal statement of collector status.
  2. Click Submit.

Delete a collection port

  1. Click Delete next to a collection port.
    • If there is the NetFlow service running on the appropriate collector server, the collector together with the default port 2055 will be automatically added again in 15 minutes. For more information, see Delete collectors in NTA.
  2. Click Submit.
