Dear Toby,

our log files among other things contain recurring event sequences. For example the user can start a measurement by clicking a button in the GUI. This leads to a typical sequence of log file entries of a certain pattern. For example.

(A) Measurement Button clicked
(B) Hardware triggered.
(C) Hardware finished measurement.
(D) Result displayed on GUI.

Between those log entries there can of course be all other kinds of log output.

For the investigation of certain problems I would often like to check the following:
a) How long did these measurements take. That is for example the difference between output (A) and output (D).
b) How long did certain parts of the measurement take. That is for example the time difference between output (A) and (B).
c) How often is a measurement triggered by the user or equivalently what is the time difference between consecutive starts of measurement.
That is the time difference between consecutive log outputs (A) and (A).

I know that I can measure elapsed time in the "Log Entry Grid" by selecting two log entries and
using the "Calculate Elapsed" function from the context menu. But usually our log files contain a lot of those measurements
and I would like an automatic evaluation for the whole log file and a list of all measured times of the log file (together with the
time instance that they occurred).

When selecting one entry of the list I would then like a possibility to go to the original log file entries.
Also very helpful would be a graphical display of the results. This would make it very easy to find outliers in huge log files.
And of course it would be very nice to store these defined measurements as a template.

Kind Regards
Andreas
