It isn't different from any other JMeter Variables
<https://jmeter.apache.org/usermanual/functions.html>
The process of adding labels to metrics is described in Using JMeter
variables as labels
<https://github.com/johrstrom/jmeter-prometheus-plugin#using-jmeter-variables-as-labels>
*sample_variables* is a special JMeter property
<https://jmeter.apache.org/usermanual/listeners.html#sample_variables>
which adds a variable value to the .jtl results file
<https://cwiki.apache.org/confluence/display/jmeter/JtlFiles>and expose
it to some other listeners like Flexible File Writer

Hi,
Inhttps://github.com/johrstrom/jmeter-prometheus-plugin/issues/3, it says
Jmeter allows for sample_variables to be populated and used in the
SimpleWriter listener class. We should also use this feature for labeling.
This sounds like a very useful feature, but I cannot grasp how to make use
of it.
Can someone elaborate with a sample use-case example please.
Thanks
