How to maintain the active number of threads during execution?
Hello,
In Jmeter, Thread group element has three options when a sampler fails:
Continue, Stop Thread, Stop Test.
If I choose "Continue", it will go through all the steps even after it
encounters a failure - this generates unnecessary error messages since my
scenario works only in series. However, it maintains the number of threads
throughout the whole test
If I choose "stop thread", the thread stops when it encounters a failure so
it does not generate junk error messages. However, the number of active
thread goes down every time this occurs.
I need a way to do this between these options: When a failure occurs in a
thread, it stops the rest of the scenarios and it restarts from the
beginning. In this way, it will maintain the number of threads and it does
not cause any junk error messages in the system. Anybody knows how I can
achieve this?
Thanks in advance.
Byungsoo Kim

No, the variable is set to true or false after every sample.
It is initially true.

Should not be necessary, but if you do have to set it one way is to
add a Java Request sampler with the appropriate status, i.e. OK or
something else.

Thanks!!
I was afraid that what you said was the solution to it. I am assuming
JMeterThread.last_sample_ok is supposed to get reset in the beginning of
each loop for a thread. However, in my past execution, I have seen the case
in which the solution failed to maintain the number of thread sometimes. I
tried to set the value of the variable to "true" by adding Simple Config
Element at the end - I do not think that it worked though since Debug
Sampler says "false".
Do you know how to force the value of the JMeterThread.last_sample_ok value
to be true?
Thanks again.

Only by using the If Controller to wrap each sampler, e.g.
Sampler 1
IF condition: ${JMeterThread.last_sample_ok}
+ Sampler 2
IF condition: ${JMeterThread.last_sample_ok}
+ Sampler 3
etc.
