Traffic Pattern view presents statistic for the specific Traffic Pattern you have previously configured. Note that Traffic Pattern node in Subnet Sets view, in contrast to normal Traffic Pattern view, shows Subnet Set distribution instead of subnets.
To show statistic for a Traffic Pattern, go to TopN > Subnet Sets option and select the Traffic Pattern node of your interest.
The Navigation Tree in the Menu Panel shows Traffic Patterns and their Subnet Sets, while Main Panel shows traffic data for for the selected Traffic Pattern (throughput or volume, in bits, packets or flows), its Subnet Sets or Subnets of those Subnet Sets. Clicking on any tab option will show traffic distribution by that category (e.g. clicking on the Subnets tab will give you top Subnet Sets for the selected Traffic Pattern).
Figure above shows traffic statistic for the All Traffic. You can see consumption of AlphaCom and InoTech Subnet Sets (an example of two organizations).
Info
Note that Subnets that do not belong to any Subnet Set will not show as child nodes of their respectful Traffic Pattern in Subnet Set view. Their contribution to traffic will be added to others category, since this view focuses on Subnet Sets instead of subnets.
