I'm not aware of any existing plugin, if you have only one
Thread Group and would like to see the response time of the latest sample in console you can add a
JSR223 Sampler as the last sampler in the Thread Group and use the following code there:
SampleResult.setIgnore()
OUT.println('Latest sampler elapsed time: ' + ctx.getPreviousResult().getTime())
- The first line instructs JMeter to not to consider the execution of the JSR223 Sampler itself (neither report it to Listeners nor store in the .jtl results file)
- The second line prints the last sampler (the one above the JSR223 Sampler) execution time to the STDOUT
