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.
Only SNMP-capable nodes whose interfaces were discovered by SolarWinds NPM can be added as NetFlow sources.
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.
- Add the appropriate nodes to SolarWinds NPM.
If you are adding a large number of nodes, use Network Sonar Discovery.
Click Settings > Network Discovery.
Confirm that you add all flow-enabled interfaces on added devices.
If you are only adding a few nodes, it may be easier to use Web Node Management in the Orion Web Console.
Click Settings > Add Node.
To finish setting up NetFlow monitoring, enable NetFlow monitoring for the selected nodes.
For more information, see Add Flow Sources and CBQoS‑Enabled Devices.
If you have already 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 displays 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 in SolarWinds NTA.
