Question

I have a simple “Java Request” sampler (ie: AbstractJavaSamplerClient). How do I produce custom variables from this sampler and graph these? (Preferably with out-of-the-box graphing listeners). Currently I can only easily graph sample times.

Answer 1

Put your var in JMeter:

JMeterContextService.getContext().getVariables().put("YOUR_VAR", value)

And add in user.properties:

sample_variables=YOUR_VAR

Your var will be output in CSV ou XML.

You can then use it.
