Running Command-Line Commands in JMeter Using Groovy

The previous two posts introduced using Groovy with JMeter for handling assertions and variables; this third article explains how to run command‑line commands from Groovy within a JMeter test.

First, create a simple Thread Group and a basic request, then add a JSR223 PreProcessor (post‑processor would run on the next request). The Groovy script uses the .execute() method to run commands such as jps -lv and jmeter -v , logging the results with log.info and log.error .

Groovy script used:

log.info("jps -lv".execute().text)

"jps -lv".execute().text.eachLine{
    log.error("222222222 ${it}")
}

log.info("jmeter -v".execute().text)

The console output shows JMeter engine startup messages, thread group execution details, and the logged command output, including error lines prefixed with the custom 222222222 tag.

Although the author is still learning JMeter, the demo is shared to help colleagues who need similar functionality; readers are invited to suggest additional use cases.
