Exec Sum in 5.0 Dynatrace
What is the difference between Exec Sum and the Duration for the Pure path?
There is a previous post from Andi Grabner that answers your question, so I will just paste the answer here and hopefully this helps:
"...
- Response Time: is the Total Execution time of the Entry Point Method that starts the PurePath (=Exec Time Root Node).
- Duration: This is the time from the First Event we receive from a PurePath until the last Event that we receive.
- Exec Sum: This is the Execution Sum of all individual Subpaths that belong to a PurePath.
Here is an Example
doGet : 100ms -> Async Path 1 --> doSomethingAsync: 500ms -> Async Path 2 --> doSomethingAsync: 500ms
Response Time: 100ms -> because doGet finishes after 100ms which means the transaction actually delivers the response back to the end user in 100ms Duration: 600ms -> assuming that the two async paths are startet at the same time and really end at the same time the Duration is 600ms because the PurePath is completed (= last event received) after 600ms Exec Sum: 1100ms -> overall it took 1100ms to execute the transaction even though some of it was executed in parallel...."
I hope this helps
Thanks now it is clear. But I have a follow up question on the Transaction Flow for the pure path. For a pure path that includes the asynchronous executions. What does the Execution Time Per transaction that shows up at each tier relating to pure path in the Transaction Flow view ?
