Documentation for NetFlow 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.

NTA flow requirements

NTA supports the following flow protocols:

Flow	Supported Versions	Sampled Flow Support
NetFlow	v1, v5, and v9 NetFlow v9 must have an appropriate template with all required fields.	v5 and v9 Some devices using IOS versions export flows without specifying that it is being sampled. NTA processes these flows as unsampled.
sFlow	v2, v4, and v5	Supported
J-Flow	Supported	Supported Some devices using JunOS versions export flows without specifying that it is being sampled. NTA processes these flows as unsampled.
IPFIX	IPFIX (v10) supported for networks running on IPv4	Supported
NetStream	v5 and v9	Supported
NetFlow Lite	Supported on the following devices: Cisco Catalyst 2960-X Cisco Catalyst 2960-XR Cisco Catalyst 3560-CX Cisco Catalyst 2960-CX	Supported
Cisco Wireless Controller NetFlow	Supported on the following devices with the ipv4_client_app_flow_record template: Cisco 2504 WLC Cisco 3504 WLC Cisco 5508 WLC Cisco 5520 WLC Cisco Flex 7510 WLC Cisco 8510 WLC Cisco 8540 WLC Cisco WiSM2	Not supported

Difference between sampled and non-sampled flow:

Sampled flow: Collects less data and provides only a sample. This prevents the network from overloading.
Non-sampled flow: Collects all data.
