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.

Top XX Autonomous Systems (Classic Chart)

This widget provides a list of the most bandwidth‑intensive autonomous systems. Autonomous systems are listed with the amount of data (kbps) transferred, in both bytes and packets, and the percentage of all traffic generated by the autonomous system over the specified time period.

When placed on the Node Details or Interface Details view, this widget provides a view of the autonomous systems responsible for the most traffic passing through the viewed node or interface over the selected period of time.

To find out more about autonomous systems monitored by NTA, see Managing Autonomous System Networks.

Click a listed node or interface to display the relevant autonomous system traffic traversing through the selected node or interface in the NetFlow Autonomous Systems View.

Table legend

The table below the chart provides the following information:

Column Title Contents
Autonomous System The autonomous system ID.
Ingress Bytes, Egress Bytes
Ingress Packets, Egress Packets 		Displays the amount of data (in bytes and packets) flowing to the selected autonomous system through the viewed node or interface.
The columns displayed depend on the flow direction set in the top left corner of the view (either only Ingress Bytes, or only Egress Bytes, or both columns).
Percent (Utilization) Displays the percentage of all traffic through the viewed object that can be attributed to listed autonomous systems.

The first value describes the percentage of the appropriate item based on items shown by the chart. Individual items in the legend add up 100%. This percentage can be absolute or relative. For more information, see Set the Percentage type for Top XX lists.

A value in parentheses is available only for interfaces. It describes how the appropriate item utilizes the interface bandwidth in percentage.

If the utilization is approximately twice as high as it should be, for example 150% instead of 75%, it might be caused by flow duplication. For more information, see Resolve duplicate flows.
