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 list widget percentages in NTA

Top XX list widgets may be configured to show any number of items, listed in either absolute or relative terms of overall traffic percentage. Absolute percentages are calculated for each item based on all monitored items. Relative percentages for each item are calculated in terms of the total number of items displayed in the selected widget.

By default, pie charts are configured to show some, but not all traffic. You can see the rest of the data not included in the top XX items in the Remaining Traffic row in the legend.

Example

A given node, HOME, is communicating with other endpoints: 1, 2, 3, and 4. The following table details the two percentage types calculated and displayed for both Top 4 Endpoints and Top 3 Endpoints widgets.
