Top XX Autonomous Systems

When placed on the Node Details or Interface Details view, this resource 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 SolarWinds NTA, see Managing Autonomous System Networks.

View more details about displayed autonomous systems

Click a listed autonomous system to open it in the NetFlow BGP Summary View.

Click + to expand a listed autonomous system and display a list of nodes and their respective interfaces relevant for the selected autonomous system.

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 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.
