Webinar: Web Help Desk for HR, Facilities and Accounting Departments
This webinar will focus on use cases for HR, Facilities and Accounting.

Having a unified ticketing and asset management system for all the departments in your company can provide end-users with a seamless experience and make things easier for your IT team. Yet, with different business tasks and objectives, many departments don’t fully understand the capabilities of Web Help Desk and how the software can be customized for effective use in their departments.

Add flow-enabled devices and interfaces to the Orion database

Table of contents

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.

To finish setting up NetFlow monitoring, enable NetFlow monitoring for the selected nodes.

For more information, see Add flow sources and CBQoS-enabled devices.

  1. 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.

      For more information, see Discovering and adding network devices in the SolarWinds Network Performance Monitor Administrator Guide.

    • 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.

      For more information, see Adding Devices for Monitoring in the Orion Web Console in the SolarWinds Network Performance Monitor Administrator Guide.

  2. Click My Dashboards > Home > Summary.
  3. Under All Nodes, verify that the devices were added.

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 is happening now?

  • 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.
