Run JMeter in command line

There are use-cases where you can't use JMeter GUI to run the script.

Eg :- during distributed JMeter load testing, run jmx from a remote machine (just using command line)

Following are the steps which I followed to run JMeter script in command line.

1. Create JMeter script in your local machine.(yes, using the GUI ;) )
2. Setup JMeter in the remote machine.
  •  SCP apache-jmeter-X.XX.zip and created jmx in step 1.
3. Access remote machine using command line. (ssh ;))
4. Move and setup apache-jmeter-X.XX.zip and jmx according to your preference.

I have extracted  apache-jmeter-X.XX.zip inside my home directory(remote machine) and able to move to bin directory using,
cd /home/udara-aws/apache-jmeter-2.11/bin
Copied test.jmx script in to the same location.

Lets run this script in command line now.
sh jmeter.sh -n -t test.jmx -l log.jtl
Here we have used -n -t and -l arguments.

-n denotes –nongui run JMeter in nongui mode
-t denotes –testfile  jmx file which needs to run
-l denotes  –logfile file to put sampler logs (jtl)

Following is the output I got, If you are not getting summery results make sure to attach "Generate Summary Results" listener to relevant samplers.
