Jmeter # of request starts to drop after few hours

Can someone help me identify what's wrong with my Jmeter, Currently I'm running 200 users and will generate 6000 request per minute. on First few hours the request is consistent at 6000 but after few hours it starts to drop.

Machine & Server is hosted on AWS FYI: I'm currently running this on Ubuntu CLI

Command used: ./jmeter -n -t ES_Scenario1_Endurancetest.jmx -l /data/apache-jmeter-5.6.2/bin/result/loadtest/ES_EnduranceTest_aggregateResult_100.csv &

Upon invocation of single API it returns more than 6000 lines of code

Solution

  • What do you want from us exactly? Your soak test fails and now you need to find the reason for the failure.

    Given you follow JMeter Best Practices and recommendations from 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article JMeter should be stable enough and suitable for the soak testing without degradation of the performance over the time.

    If you believe that JMeter causes requests slowing down you can use a profiler tool like YourKit or JProfiler to check what causes the slowing down. Alternatively instead of your endpoint you can try using a different one like http://example.com or https://blazedemo.com and see if the problem is reproducible. If yes - raise an issue in JMeter project

    However I believe JMeter is quite mature and free of obvious memory leaks so my expectation is it's a bug in the application you're trying to test so consider applying the same exercise with profiling tools.
