System Variable for Response Time?

Former Member — Mon, 11 Aug 2008 15:08:46 GMT

Hi Folks,

does anyone know if there exists a System Variable that shows me the response time of a Function?

I want to implement a performance Check of different functions and show a line Graph of the response Time. Any Hints would be highly appreciatet!

Not a system variable, but you would need to do this measurement manually. You can use the following to measure any runtime.

DATA: lr_runtime TYPE REF TO if_abap_runtime,
      lv_start TYPE i,
      lv_end TYPE i,
      lv_runtime TYPE i.

lr_runtime = cl_abap_runtime=>create_hr_timer( ).

lv_start = lr_runtime->get_runtime( ).

* Do some processing
WAIT UP TO 5 SECONDS.

lv_end = lr_runtime->get_runtime( ).

lv_runtime = ( lv_end - lv_start ) / 1000.

WRITE: / ' time per call in microseconds: ', lv_runtime.

Regards,

no there is no such a variable, because the measurement causes an overhead, i.e. time is only measured on demand, i.e. use command get runtime field start and ... stop, t = stop-start.

And don't forget to repeat measurements, otherwise your measurements will cause only confusion. Graphics ... waste of time, better implement the improvement.

Why not simply use SE30?

no so easy with SE30.

And runtime measurements can be done in a loop, gives better results.

The SAPGui has a response time indicator for the last interation with the app server. I'm curious if there's a way of reading that, perhaps one of the gui/fe classes.

( Not useful for the original poster, I'll grant you ).

Try this....

Data: T type I.

Get Run Time Field T.

write:/ T.

Select * from VBAK INTO table ITAB.

Get Run Time Field T.

write:/ T.

Hope it helps.

interesting so much confusion in such a simple question!

@Rich

lv_runtime = ( lv_end - lv_start ) / 1000.

What is the divide by 1000 good for? I am not aware that anything measure in nanoseconds.

The GUI shows response time, but response time is not runtime.

Last posting, why is the difference not calculated, if you repeat already given answers, then please improve them!

Obviously, but the op said "response time", not run time.

Correct, but what he actually seems to mean is "run time", since he's talking about the time certain functions take to execute. I would put the term "response time" into the GUI/network domain.

I might be completely wrong, let me know if so. Only the OP can clarify, I think, we're all guessing.

yes that is true, but is also obvious that only runtime make sense in the original question

Yes i mean runtime, my fault. sorry for the confusion!

Anyway, thank ya all for responsing. Im using the interface abap_runtime right now, it does excactly what im looking for, thank you Rich!
