How to check if variable value is getting used previously in jmeter

[Amruta Deokar]

Hi ,

I am using distributed testing of jmeter and sending load through master slave machines.

I am generating random variable values. 

if variable 'x' has 'abc' value then how to do i check  if same value 'abc' is getting used/generated again by any thread while generating load ? 

if same value is getting again then i have to apply some logic on another variable 

Is it possible in jmeter to check value of variable between threads?

Any help here please

As per JMeter documentation "Variables are local to a thread"

So you cannot check whether the variable was "used" by another thread, especially in distributed mode.

One of possible options is pre-generating the random variables somewhere in setUp Thread Group and writing them to a CSV file with Flexible File Writer. This way you will get confidence that the variable will be used only once.

Alternative options is using 3rd-party variables sources like HTTP Simple Table Server or Redis Data Set
