Update as of November 2017:

Since JMeter 3.0, last version being 3.3, JMeter provides Out Of The Box a dynamic Web report with tons of information.

You can read an up to date blog (15th january 2019) described here.

We highly advise you to use it instead of what is described below which is no more necessary.

Report contains more sexy graphs, tables (Errors synthesis, Top 5 errors by sampler, APDEX…) that will help you analyze your load test more easily and open it in a Browser.

Creating it is just a matter of adding 2 more command-line options in NON GUI load test.

We are the proud implementers and contributors of this web-report that was partly sponsored by Decathlon (a great French and worldwide sports company).

Context

You are using Apache JMeter for your Load Tests.

Once test has ended, you would like your favorite tool to automatically generate for you nice and meaningful graphs so that you can faster analyze your test results and include them in your report.

Apache JMeter is great in many ways but its core lacks this built-in feature, but it’s plugin Architecture will let us add it easily.

Hopefully a great must have Open Source and free third-party library called JMeter-Plugins comes to the rescue.

Before version 1.1.3 of JMeter-Plugins, you could use JMeterPluginsCMD Command Line Tool to generate your graphs in a shell, but this was not optimal.

As users of both Apache JMeter and JMeter-Plugins, we decided to contribute this new feature to JMeter-Plugins.

Our philosophy is :

• “If you use an Open-Source and free project, be grateful, always contribute in a way”

Feature Overview

To automatically generate your reports just add a new Listener called “jp@gc Graphs Generator“.

You can define the following properties:

JMeter Setup:

JMeter-Plugin installation:

• Use JMeter version >= 2.10
• Download extras bundle and unzip it, copy lib/ext/JMeterPlugins-Extras.jar to <jmeter home>/lib/ext.
• Restart jmeter.

JMeter Configuration:

Edit <jmeter home>/bin/user.properties and ensure you set these properties:

jmeter.save.saveservice.output_format=csv

jmeter.save.saveservice.data_type=false

jmeter.save.saveservice.label=true

jmeter.save.saveservice.response_code=true

jmeter.save.saveservice.response_data.on_error=false

jmeter.save.saveservice.response_message=false

jmeter.save.saveservice.assertion_results_failure_message=false

jmeter.save.saveservice.successful=true

jmeter.save.saveservice.thread_name=true

jmeter.save.saveservice.time=true

jmeter.save.saveservice.subresults=false

jmeter.save.saveservice.assertions=true

jmeter.save.saveservice.latency=true

jmeter.save.saveservice.bytes=true

jmeter.save.saveservice.hostname=true



# This will enable correct graphs display 

# which deal with threads after reloading the results file.

jmeter.save.saveservice.thread_counts=true



jmeter.save.saveservice.sample_count=true

jmeter.save.saveservice.timestamp_format=HH:mm:ss

jmeter.save.saveservice.default_delimiter=;

jmeter.save.saveservice.print_field_names=true

# This is needed to ensure all results are 

# available when Listener runs

jmeter.save.saveservice.autoflush=true

Test Plan setup:

If using distributed testing, ensure you add to your Thread Group names:

${__machineName()}_My Threadgroup name

Test Plan example:

We will use a test plan you can easily create with Templates…> Building a Web Test Plan

We just added an Http Cookie Manager and removed Graph Results listener.

We end up with this, the only listener is the new jp@gc Graphs Generator

Let’s run plan:

Now run this plan in NON-GUI mode as per JMeter Best-Practices using following command-line:

./jmeter -t GraphsReportListener-GenerationAtEndOfTestNonGUI.jmx -n

  -l /data/jmeter/test-results.csv

 -JTEST_RESULTS_FILE=/data/jmeter/test-results.csv

Notice the following:

1. -t GraphsReportListener-GenerationAtEndOfTestNonGUI.jmx : Means use following jmx file GraphsReportListener-GenerationAtEndOfTestNonGUI.jmx
2. -n : Means NON GUI
3. -l /data/jmeter/test-results.csv : Means output results in following file
4. -JTEST_RESULTS_FILE=/data/jmeter/test-results.csv : Notice we set the same value as output file in 3). We set this because in “jp@gc Graphs Generator” we have used __P function in JMeter to replace TEST_RESULTS_FILE by the value we input in -J:
   • ${__P(TEST_RESULTS_FILE,/data/jmeter/test-results.csv)}

   

In this configuration, notice we have decided to only include 2 samples:

• Home Page
• Changes

In a real worl scenario, you would use Transaction Controller for meaningful transaction names and only include those in your report.

Results:

At end of test JMeter automatically generated in <jmeter home>/bin folder the following files:

Graphs:

Response Times over time:

Hits Per Second:

Bytes throughput over time:

Latencies over time:

Response codes per second:

Response times distribution:

Response times percentiles:

Threads state over time:

Time vs Threads:

Transactions per second:

Throughput vs Threads:

Other Features

Graphs Generator Listener can also generate CSV files besides PNG files.

Graph Generator Listener can even generate graphs for existing results, to do so, create a fake plan like the following:

Run it in GUI or NON-GUI mode, the graphs will be generated.

Ensure you use the same properties configuration you used during the test that generated the results you are graphing.

NDLR:

With this new Graphs Generator Listener , you can now easily:

• Generate meaningful and sexy graphs at the end of your test
• Generate meaningful and sexy graphs for existing results any time you want
• Output CSVs with computed datas at end of your test if you want to use custom graphs
• Output CSVs with computed datas for existing results any time you want if you want to use custom graphs
