As an example, suppose I'm trying to count the number of concurrent HTTP sessions. Events look something like the following:
Event 1: start=[02/05/2013 13:18] end=[02/05/2013 14:20]
Event 2: start=[02/05/2013 13:58] end=[02/05/2013 15:50]
Event 3: start=[02/05/2013 13:50] end=[02/05/2013 14:02]
What I'm trying to do is count the number of concurrent sessions over some range of time, say 24 hours. So in the above example, I'm trying to get the following:
Date Active Session Count
02/05/2013 13:30 1
02/05/2013 14:00 3
02/05/2013 14:30 1
Is something like this possible?
