Looking to compare latest NPM features with previous versions of NPM?
The NPM new feature summary offers a comparison of new features and improvements offered with this release.
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.
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.
The table below the chart provides the following information:
|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.
If you are logged in using a User ID with administrative privileges, you can change the way this resource is displayed for all users:
You can also change the time period and flows direction shown by all resources in the view:
The time and flow direction settings are limited to the current session only. After you leave the view, your changes will be lost and default settings are re-applied.
