Add flow-enabled devices and interfaces to the Orion database

SolarWinds NTA collects flow data from your network devices and analyzes network traffic based on collected data.

To collect flow data, you must specify the SolarWinds NTA server as a target to which each device exports data. For more information, see Set up network devices to export NetFlow data.

To analyze flow data, you must add each flow-enabled network interface to the SolarWinds Orion database, so that they can be monitored in SolarWinds NPM.

To initiate flow monitoring, flow-enabled devices in the SolarWinds Orion database must be designated as flow sources. For more information, see Add flow sources and CBQoS-enabled devices.

Adding flow-enabled devices and interfaces to SolarWinds NPM and designating the same devices and interfaces as flow sources in SolarWinds NTA are separate actions. The designation of flow sources does not affect licensing requirements for either SolarWinds NPM or SolarWinds NTA.

  1. Add nodes to SolarWinds NPM.
  2. Click My Dashboards > Home > Summary.
  3. Under All Nodes, verify that the devices were added.

If you have configured device interfaces to send flow data, SolarWinds NTA can detect and analyze flow data after the device is added.

What happens after you add devices and interfaces to the Orion database?

  • After installing SolarWinds NTA, the SolarWinds NPM polling engine establishes a baseline by collecting network status and statistics.
  • Thirty seconds later, the SolarWinds NPM polling engine performs another collection. You may notice an increase in the CPU usage during this time.
  • After these initial collections, SolarWinds NPM collects network information every ten minutes for nodes and every nine minutes for interfaces. Flow analysis data are displayed in the Orion Web Console in minutes.

Before leaving SolarWinds NTA to gather data, ensure you are collecting flow data for the correct interface ports and applications. For more information, see Applications and service ports.
