How to extract maxValue_max from jsr223 sampler to the next request? I see that the sampler determines the maximum value, how now to extract and use it?
You do have the value written into a JMeter Variable already, you can just call ${maxValue_max}
where required and the variable will be resolved to its respective value.
Or if you prefer Groovy scripting you can use __groovy() function like:
You might also want to call SampleResult.setIgnore()
function somewhere in your script so the JSR223 Sampler won't appear in the test results or just switch to JSR223 Post-Processor.
