jmeter - showing the values of variables

Question

My group does a lot of test automation with JM. Typically we have a properties file which has a bunch of variables defined. These in turn are mapped to \"User Defined Variables\

Answer 1

The newest versions of Jmeter have a fantastic sampler called "Debug Sampler" that will show you the values for: Jmeter Variables, Jmeter Properties or System properties.

You can insert them wherever you want in the script to get values at a given time. You'll want to have a "View Results Tree" enabled to view the sampler.

Given that Jmeter declares variables from a file on run, you won't be able to get your ideal solution.

I'm curious...would it be cleaner to employ "CSV Data Set Config" rather then populating "User Defined Variables" from a properties file?

Edit: Added explanation on variable declaration and asked CSV question.
