Hello Monks! I have a situation where I need to calculate the time between two events in a log file. The log format is like this. Each login has a pair of events, invoke and success. The time of the event is in the second column. I need to correleate the events and report the time it took for them to complete. For extra credit, I will then look to generate 15 minute, 1 Hour and 3 Hour Averages for these events. If you know any way to accomplish this I would be forever grateful.
