Counter in multiple ThreadGroup iterations
Hello,
when I configure a ThreadGroup for multiple iterations, a Counter
used to process sub-page parameters inside a Loop is not resetted,
but starts off with the value of the
previous Threadgroup-cycle (even though I checked the "each user" -
Option, or use only a single Thread ).
Do I miss something?
Thanks a lot,
Max

Hi Andrey,
sorry for complicating things by omitting the basics, but I really
meant the most simple case:
a GET-parameter called 'page' which is extracted from the response.
The reason not to use the RegEx Processor / ForEach Loop is that
there are only very few navigational links presented to user, so I
concentrated on the last one (pointing to the last page), to compute
the number of follow-up requests I would need.
But since the Counter doesn't work for me, I now apply a ForEach
Controller by declaring variables the way the RegEx Processor would do.
I just wanted to be sure not to miss something before reconfiguring,
but in the end the changes were done very easily.
Thanks again for the quick advice,
Max

Hi,
what do you mean by "sub-pages"? Page frames? Redirects on your http
request? Or just pages you will request after parsing the response of
the first request? What is a "page number" - GET parameter in your
requests? And how exactly do you use the Counter to "fill Get
parameters"?
Why cannot you just use the e.g. RegExp or XPath Post Processor to
extract the links for your following request and then loop over those
in a ForEach Controller?
Regards,
Andrey

Re: Counter in multiple ThreadGroup iterations
Posted by mburns <m....@digiden.de>.
Hi, and thanks a lot for the quick response!
I'm using it for looping through sub-pages of a given start-url.
Due to the design of the sub-page navigation (only very few follow-up
pages are displayed) I don't want to use a for-each construct.
Instead I extract the "last" sub-page link via XpathExtractor and
pass the page number after some cleanup in a BSF Postprocessor to a
Loop Controller.
Inside the Loop Controller, a Counter is used to fill a Sampler's GET-
Parameter.
This worked fine, but since I would like to simulate a steady stream
of requests by restarting my ThreadGroup, and the counter won't reset
on each iteration, I will have to find another solution.
My next try will be to write url-variables within the BSF
Postprocessor, and pass those to a For-Each Controller.
Or is there a better way?
Regards,
Max

Hi,
this is working as intended - Counter will live on with the thread(s),
and is only set to its starting value once - when it is first
referenced. It will keep its value from loop to loop.
What are you using it for?
Regards,
Andrey
