As in above picture there are in total 5 transaction which results is total duration to be 66, that means 1min and 6sec, that does not shown in session duration time.
Hi Mattis,
the t.duration actually refers to the processing time in milliseconds for that transaction in Teneo Engine. Here’s the reference for what the various properties refer to Transaction properties - teneo log data .
The way to calculate the duration of the session would be to calculate the time between s.beginTime and s.endTime which is what I believe is shown in Teneo Studio.
