Graphs Generator Listener ^{since 1.1.3}

Description

Graphs Generator Listener generates the following graphs at end of test:

• Active Threads Over Time
• Response Times Over Time
• Transactions per Second
• Server Hits per Seconds
• Response Codes per Second
• Response Latencies Over Time
• Bytes Throughput Over Time
• Response Times vs Threads
• Transaction Throughput vs Threads
• Response Times Distribution
• Response Times Percentiles

It also generates since version 1.2.2:

• a CSV file containing the Aggregate Report data
• a CSV file containing the Summary Report data

Graphs Generator Listener requires JMeter 2.10 or superior. You can use this listener in 2 ways:

• to generate CSV or PNG or both formats for current test results
• to generate CSV or PNG or both formats for existing/previous test results

Generate CSV / PNG for current test results

To do this, you have to ensure Results are flushed to file so that when Graphs Generator Listener runs, it does on a complete file.

You have 2 options:

• Configure a View Results Tree so that it outputs results to a file (Use this listener only in NON-GUI mode for performance purposes)
• Ensure View Results Tree listener is BEFORE Graphs Generator Listener

Change JMeter settings in user.properties to ensure autoflush is used:

• jmeter.save.saveservice.autoflush=true

In this case, you just need to put Graphs Generator Listener as only listener and run in NON-GUI mode

Generate CSV / PNG for existing/previous test results

To do this, you will have to create a "Fake" test to trigger listener on existing file.

This is very simple:

• Create one thread group with 1 thread and 1 iteration
• Put a debug sampler as child of it
• Run test
• PNGs or CSVs or Both files will be generated for the results file you have configured in Graphs Generator Listener
