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.

Applications and service ports in NTA

Use NTA to directly specify the applications and ports you want to monitor. Additionally, you can specify protocol types by application, giving you the ability to monitor multiple applications on the same port if each application uses a different protocol. You should review this list of ports and applications and check the ports and applications you want to monitor, adding any that are not present.

By default, NTA monitors recommended ports and applications that are used most on typical networks.

NTA supports many applications out of the box. However, if you have custom internal applications, remember to assign a port name and number to them so that they are reported correctly and not marked unknown.

Access the applications and service ports settings

  1. In the SolarWinds Platform Web Console, click Settings > All Settings.
  2. Under Product Specific Settings, click NTA Settings.
  3. Click Application and Service Ports.

To monitor ports on a server, you first need to create an IP address Group and then two applications:

Let's assume you have a server with an IP address 1.1.1.1 and you want to monitor ports 80 and 443 on that server.

  1. Add an IP address group with the IP address 1.1.1.1. For more information, see IP address groups in SolarWinds NTA.
  2. Create an application called Application1 with ports 80 and 443, and select your new IP address group as the Source IP Address.
  3. Create an application called Application2 with ports 80 and 443, and select your new IP address group as the Destination IP Address.

    You cannot create a single application when monitoring ports on a server.
