transaction duration

[Prasenjit Dutta]

Hi Guys....

Do you have any idea why the trasaction response time that we are
getting with transaction duration function is less than what it is
coming in lr_end_transaction.

Ideally it should be slightly greater than the end transaction as it
contains the wasted time too.....but in my case it is alws lesser
:-(...any idea???

See there can be many reasons for this thing  yes one of them is waste time. Other one is bad practice for scripting. Always keep text checks wrspm etc should be out side strt-end trans

[piyush gupta]

transaction duration function  is called  by lr_end_transaction internally.that's why..

[Prasenjit Dutta]

please check the help file it says...the value returned by transaction
duration may be greater than what end transaction is returning.....as
transaction duration returns value with the wasted time.........but in
my case transaction duration value is slightly less than what end
transaction is returning........so i am just confused which one is
actually correct.......

where r u looking  time .......vugen replay log or in controller.....

then hard to conclude anything......

Lr_end_transaction() and lr_get_transaction_duration() both include wasted time and think time.  It is natural for lr_get_transaction_duration() to be shorter in duration if called prior to lr_end_transaction() because of the small number of microseconds/milliseconds between each statement execution…which could be made longer if you have any logic between the two statements.

Thanks James, I was also thinking like this way as lr_get_transaction_duration is called before lr_end_transaction, so it should be slightly less than the what lr_end_transaction returns. But the help file tells the different story (This function returns the duration including Wasted Time. Therefore, the value may be slightly greater than the duration reported for the function when closed with lr_end_transaction.) and that is why the confusion arised for me.......

hi prasenjit,

if you will read wasted time in help file  last three lines are

" in the on-line graphs in the LoadRunner Controller and the transaction response time graphs in the LoadRunner Analysis, the transaction times are reported after subtracting the wasted time. This is the time most pertinent to understanding the system being tested. "....so it might be the case that they are comparing that time(lr_end_transaction) to this lr_get_transaction_duration time.

[James Pulley]

Don't confuse how it is collected with how it is reported. Look at
the [event meter] table in your analysis database files (msaccess mdb
or sql server). The field names should be enlightening.
