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.

NetFlow Node Details

Under NetFlow Sources, click a router name to open the NetFlow Node Details view.

Node Interfaces

This widget provides a list of all monitored interfaces on the viewed node. For each interface, both incoming and outgoing traffic are reported. Click an interface to open the NetFlow Interface Details.

Top 10 Applications

This widget provides a quick view of the applications used most by the viewed node. The table below the chart provides the application name, the amount of data that is flowing, the equivalent total number of packets, and the percentage of all traffic that is traceable to use of the listed application by the viewed node. Click an application to open the NetFlow Applications Summary view.

Top 5 Conversations

This widget provides a list of conversations that are creating the most traffic over the viewed node. For each conversation, this widget reports the amount of data transferred in the conversation and the percentage the listed conversation represents of the total data transferred over the viewed node. Click a conversation to open the NetFlow Conversations Summary view.

Top 50 Domains

This widget provides a quick view of the domains that are producing the most traffic on the viewed node. The table below the chart provides the domain name, the amount of traffic in bytes, the total number of packets communicated, and the percentage of all traffic on the viewed node traceable to each domain. This widget is only available if persistent DNS resolution is enabled. By default on evaluation installations, DNS resolution is configured to occur on demand only. For more information, see Configuring DNS and NetBIOS Resolution in the SolarWinds NetFlow Traffic Analyzer Administrator Guide.

Top 5 Endpoints

This widget provides both a chart and a table view of the endpoints producing the most traffic over the viewed node. The table below the chart provides the name or IP address of each listed endpoint, the amount of traffic from each listed endpoint, in both bytes and packets, and the percentage of all traffic over the viewed node that is traceable to each listed endpoint. Click an endpoint to open the NetFlow Endpoints Summary view.

Top 5 Protocols

This widget provides a view of the traffic protocols the viewed node uses most. The table below the chart provides the protocol type, the amount of data, the total number of packets, and the percentage of all traffic on the viewed node using each listed protocol.
