Jmeter non-gui mode running in Linux or Unix environments?

1 Use JMeter in non-GUI mode

• Find where you installed JMeter through command line or the terminal
• Set the ‘bin’ directory as your current directory
• Run ‘jmeter –n –t <location of script>.jmx
• That’s it, when your test is complete you can do your analysis. You may be interested in seeing how your test is performing  during execution in command line/terminal (rather than seeing a black window), to do this just uncomment the following within the JMeter properties file (remove the ‘#’):

#summariser.name=summary
#summariser.interval=180
#summariser.out=true

2 .Remove or at least disable listeners you don’t need. Typically listeners such as the ‘View Results Tree’ consume large amounts of memory purely down to how much information it gathers.

• Simply take a second look at your script and remove the listeners you don’t need.

3  Increase the JMeter heap memory

• Within your explorer find where you installed JMeter
• Open up the bin directory.
• Find the ‘JMeter.bat’ file and open it with a text editor
• Find the following ‘set HEAP’
• You can set this HEAP value to whatever you like, in this example I’ve said allocate 2 GB of memory from the start and throughout the test run: ‘set HEAP=-Xms2048m -Xmx2048m’

Please note if you increased the allocated JMeter heap memory remember that you need to have Java runtime environment 6 or above. What you may notice is you’re unable to allocate more than 2 GB of memory; this happened to me, JMeter refused to open, and was the cause of the JMeter only being able to use 1 CPU core. A quick fix for this is to install the 64 bit Java runtime environment, this should alleviate the problem.

I hope this helped you, for my testing it did. If you have any questions or just liked this article feel free to leave a reply. If you want more information on best practices with JMeter please take a look at this link:
