How to generate JMeter Composite Graph using CLI?

Question

I have a test plan with Composite Graph inside it. Everything is working fine when using GUI. Unfortunately, I got this error when trying to generate that graph using CLI:

$ ~/apache-jmeter-5.2.1/bin/JMeterPluginsCMD.sh --generate-png test.png --input-jtl hg-cws-test-plan-v3.jtl --plugin-type CompositeGraph

What did I missed here? What does that kg.apc.jmeter.vizualizers.CompositeResultCollector cannot be cast to kg.apc.jmeter.vizualizers.CorrectedResultCollector actually means here?

Answer 1

Looking into Plugin Type Cases I fail to see CompositeGraph there:

• AggregateReport = JMeter's native Aggregate Report, can be saved only as CSV

• SynthesisReport = mix between JMeter's native Summary Report and Aggregate Report, can be saved only as CSV

• ThreadsStateOverTime = Active Threads Over Time

• BytesThroughputOverTime

• HitsPerSecond

• LatenciesOverTime

• PerfMon = PerfMon Metrics Collector

• DbMon = DbMon Metrics Collector, DataBase, get performance counters via sql

• JMXMon = JMXMon Metrics Collector, Java Management Extensions counters

• ResponseCodesPerSecond

• ResponseTimesDistribution

• ResponseTimesOverTime

• ResponseTimesPercentiles

• ThroughputVsThreads

• TimesVsThreads = Response Times VS Threads

• TransactionsPerSecond

• PageDataExtractorOverTime

• MergeResults = MergeResults Command Line Merge Tool to simplify the comparison of two or more load tests, need properties file (like merge-results.properties)

So most probably you're trying to call the functionality which hasn't been implemented yet.

You can reach out to the plugins developers/maintainers at JMeter Plugins Support Forum, they better know the product than anyone here.

In the meantime you can consider alternative solution like BM.Sense where you can create whatever composite charts you want using a fancy web interface. The BM.Sense Uploader plugin can be used for automatically uploading the results during the test execution.
