Generating JMeter Test Reports via Command Line and Plugins

The article uses Apache JMeter 3.2 and demonstrates how to generate test reports and charts from JTL files.

1. Command‑line mode to convert JTL to a test report

Applicable to JMeter versions 3.0 and later. Execute the following command:

jmeter -n -t test_request.jmx -l test_result.jtl -e -o /home/csmijo/resultReport

Parameter meanings:

-n : non‑GUI mode

-t : path to the test plan (.jmx)

-l : output JTL file

-e : generate the HTML report after the test

-o : directory where the report will be created (must not already exist or must be empty)

To generate a report from an existing JTL file: jmeter -g log.jtl -e -o resultReport Parameters:

-g : existing JTL file

-e : generate report

-o : output directory

2. Plugin mode to create charts

Various chart plugins are available, such as AggregateReport, SynthesisReport, ThreadsStateOverTime, PerfMon, etc.

To use the plugins, download jpgc-cmd-2.1.zip from the JMeter Plugins site and place its contents into the JMeter bin directory. Additional required components include jpgc-filterresults-2.1.zip, jpgc-synthesis-2.1.zip, and the standard plugin set (e.g., jpgc-perfmon, jpgc-graphs-basic).

Example commands:

JMeterPluginsCMD.bat --generate-png cpu.png --input-jtl cpu.jtl --plugin-type PerfMon

JMeterPluginsCMD.bat --generate-csv cpu.csv --input-jtl cpu.jtl --plugin-type PerfMon

After installing the necessary JAR files ( JMeterPlugins-Standard.jar and JMeterPlugins-Extras.jar) into jmeter/lib/ext, you can batch‑generate all supported plugin charts using a script.

The article concludes with reference links to JMeter Plugins CMD documentation, performance testing tutorials, and JTL parsing resources.
