I am trying the following search. EXECUTED, TRANSLATION_UID, DOCUMENT_TYPE are present in the logs but MAP_TYPE and MAP_NAME are not yet added. They will be added later. The search should work without them and MAP_TYPE, MAP_NAME should get added to the group by list once they are in the logs. ...| stats sum(EXECUTED) as Total_Time, count as Num_of_Executions, avg(EXECUTED) as Avg_exectime, perc80(EXECUTED) as 80th_percentile BY TRANSLATION_UID,DOCUMENT_TYPE, MAP_TYPE*,MAP_NAME* I tried the above seeing the following search for adding optional fields as follows: table Total_Time,Num_of_Executions,MAP_TYPE* MAP_NAME* TRANSLATION_UID DOCUMENT_TYPE It works. But when I added ' * ' to fields in group by list it does not work. Thanks for your help in advance!! ... View more
