Insight Analytics Flow Connections Dashboard


The Connections tab displays the following information:


  • Top L4 Services by Connections – displays connections types such as https, http, and more.
  • Top Clients by Connections – displays the top client connections by host name.
  • Top Domains by Connections – displays the top domains such as pluribusnetworks.com and more.
  • Top Servers by Connections – displays the server with the highest number of connections in descending order.
  • Connections by State – displays the types of connection states as FIN, RST, SYN, or EST.
  • Top Switches by Total # of Connections – displays the total number of connections per switch.


Each individual tile contains a pie chart with a color legend that labels each slice of information with a specific color.


When you place your cursor over a name in the legend, the corresponding slice is highlighted in the pie chart.


Clicking on a pie slice, applies a global filter to the entire Dashboard.


As an example, filtering based on an application by clicking on the application slice, automatically pivots the entire dashboard around that application and the Top Clients, Top Server, etc., are now related to the filtered application.


Dashboard widgets can be enlarged for better viewing using the sizing arrows.

The outside ring of the pie chart identifies the state of each connection. The color can be matched to the Connections by State pie chart.
