The column that I'm interested in computing is the 'Elapsed' column shown in the above table. The 'Comment' column is for instructional purposes of this post and depicts the formula pattern.
As you can see, most of the durations are simple delta _time computations. However, there are a few (indicated by <--) that compute the difference with a log entry occurring much earlier (this is case for nested method calls).
I would also like keep the representation order of the log entries as shown in Table 2.
Any help from folks experienced with such computation is appreciated.
The specialized computations really point to scripting this using REST calls and some custom business logic to handle the special cases. I can't really see any way around it. I suppose if the list and the special computations are static, you could use something like mvindex to do some gymnastics, but it just seems like a more supportable route to write a python script.
