Currently, we show runtimes for major fragments, and min,max,avg times for setup, processing and waiting for various operators.
It would be worthwhile to have additional stats for the following:
%Busy - % of the active time for all the minor fragments within each major fragment that they were busy.
%Busy - % of the active time for all the fragments within each operator that they were busy.
Records - Total number of records propagated out by that operator.
