thank you very much for your KB-Post. The sum of the primary channel is shown in the top table of such reports.
A sum-value is not really possible at the bottom of each column, as for Traffic Sensors (for example), adding up the average speed values does not make sense (nor does it for CPU Loads or Free Space on Disks). If the sum of the Traffic Total Channel is most interesting for you, please set this channel then to be the Primary Channel.
