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 Endpoints

This widget provides an at‑a‑glance chart view of the monitored endpoints that are producing the most traffic on your monitored network.

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

There are always two endpoints for each communication packet processed through a network device, and the total traffic counted for endpoints can thus seem double what it is.

To find out more about resolving endpoint names, see Configuring DNS and NetBIOS Resolution.

View more details about displayed endpoints

Click an endpoint to open the NetFlow Endpoints Summary view. For more information, see NetFlow Endpoints Summary View.

Click + to expand a listed endpoint and display a list of the nodes and their respective interfaces over which traffic to or from the selected endpoint is currently flowing.

Click a node or an interface to display the appropriate endpoint traffic related to the selected node or interview. For more information, see NetFlow Endpoint View.

Top XX Endpoints (Endpoint Centric)

You can customize an endpoint-centric version of this widget and place it on the NetFlow Node Details or Interface Details view.

The endpoint-centric Top XX Endpoints widget provides a ranked list of endpoints to which the selected node or interface initiated or terminated traffic.

For more information about adding endpoint-centric widgets, see Add endpoint-centric widgets to NTA views.

Table legend

The table below the chart provides the following information:

Column Title Contents
Hostname Displays the endpoint hostname or IP address.
Ingress Bytes, Egress Bytes
Ingress Packets, Egress Packets
Displays the amount of traffic, in both bytes and packets, through the viewed object traceable to the listed endpoint over the selected period of time.
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 over the viewed object that is traceable to the listed endpoint.

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.

Edit the widget

If you are logged in using a User ID with administrative privileges, you can change the way this widget is displayed for all users:

  1. Click Edit to load the Edit Resource page.
  2. Make changes.
  3. Click Submit.

Edit time and flow direction for the view

You can also change the time period and flows direction shown by all widgets in the view:

  1. Directly below the view name, click next to the appropriate setting and define the appropriate settings.
  2. Change the Relative Time Period, by default set to 1 hour prior to the current time, or specify a specific time period.

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.
