Totally confused with Elapse time and Exec time
Can you please explain this where this is taking time? I am totally confused with Elapse time and Exec time. Exec time is absolutely fine and within limit.
Also I noticed that web server is taking long time to respond whenever it unable to call app server (There is no trace in Dynatrace). This may cause web server thread busy. I think something is wrong in the web server. Please see the screen shot below.

Hi Naveen,
I would also add the "Exec' column on the call stack...the elapsed time is the time it took from the start of the PurePath to the entry of a method...from your screen shot it took 88928ms for the request to start processing on the app server (meaning 88928ms was spent before the request hit the app layer) - when you add the 'Exec' column you will see that all that time was spent on the Web server itself...'exec' time indicates time spent in that method only, whereas 'exec total' indicates time spent on the parent method plus sub methods. There are several posts discussing how to investigate high exec times observed on the web layer...in the below post Andi has references to those other postings https://community.dynatrace.com/community/pages/vi...
Hope this helps,

Thanks a lot Srikar for giving me right direction. I have added the "Exec" column and sees the time is spent on the webser even before hitting the app servers. But, not sure what is happening on the webserver. I will go over the references on how to investigate on web layer
