I am trying to execute my JMeter script via Azure Load Testing, I have setup a duration time in the JMeter script but when I execute via Azure Load Testing ,it does not get reflected, I cant figure from where the time is getting set. I am not sure how to configure that or where it gets overridden. Any support is appreciated.
If you provided duration_in_sec in your Azure Load Test Configuration - it will override whatever you have in the .jmx test script
If you didn't - the duration will be taken from the Thread Group(s)
If you haven't specified duration in the Thread Group - the test will end as soon as the last thread (virtual user) executes last iteration of the last Sampler in the last Thread Group.
Otherwise you test will run forever.

I am trying to run the JMeter test plan in the GitLab pipeline and facing a strange issue that Setup Thread Group doesn't run when the test plan is triggered.
JMeter Version : 5.4.1
Java : Open JDK 11
System : Linux
The test plan starts running all the other thread groups without running the Setup Thread Group first causing the test to fail completely. I am running JMeter in non gui mode.
Tried disabling all other thread group and still the problem persists
I can think of 2 reasons for not running the Thread Group, no matter whether it setUp, tearDown, normal or custom:
The number of threads is 0
The Thread Group has CSV Data Set Config and the CSV file is not present
The Thread Group has a JMeter Plugin and the plugin is not installed
Normally JMeter reports the fact of starting and stopping threads in jmeter.log file, you can take a look there and see what's going on. Additionally you can increase JMeter's logging verbosity to DEBUG level if normal level doesn't show the root cause of the unexpected behaviour.
And last but not the least according to JMeter Best Practices you should always be using the latest version of JMeter so consider upgrading to JMeter 5.5 (or whatever is the latest stable version available at JMeter Downloads page)
While running the script in non-gui mode for jmeter tests, test gets completed but it does shows min: 0, max: 0...
note:
JMeter 5.4 is installed without any 3rd party plugin.
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)
Please help
It means that none of Samplers were executed and the reasons could be in:
The number of threads in Thread Group is 0
The test contains CSV Data Set Config and the .csv file is not there
The test relies on a JMeter Plugin which is not installed
etc.
The reason should be in jmeter.log file, check it and I believe you will find either the cause or at least a clue there.
Also be aware that according to 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article you should always be using the latest version of JMeter so consider upgrading to JMeter 5.4.1 (or whatever is the latest stable version available at JMeter Downloads page) on next available opportunity
I guess you probably found the answer - but maybe this response will be useful to someone.
I've been battling a similar issue -> locally all was working fine (in GUI and non-GUI mode), but as soon as I tried to run the jmx on the server I could see it would start threads, all logs seemed normal (standard info logs within jmeter.log at start) but still no requests were actually made (confirmed by observing logs from the target server). I tried running trace logs but still nothing out of the ordinary - I could see proper HTTP config, threads were as if normal... But the generated jtl file only contained a header and no requests actually were made.
After some hair pulling I finally found my issue - I'm using variables for threads, rampup and loop which I invoke using ${__P(threads,)} syntax and when running the non-GUI load test I pass those with -J to the command line (f.ex. jmeter -Jthreads=50 ...)
I didn't pass the loop parameter since I figured it would just default to 1 (and that is also the impression I get when looking at the logs where I see all thread started ... entries) - turns out for some reason it will log, but won't execute anything actually till I pass a value for that loop.
So if you run a test plan and notice it only simulates doing something but you get no results in the target log file -> confirm you're setting ALL variables used for thread groups including those you suspect to default
We are running Jmeter scripts in Scheduler mode for 1 hour (Master - 4 Slave machines), however the execution gets over/stopped before 1 hour time (ex: it stops in 40 mints).
Below is the setup: Jmeter version 5.1
Thread Group: Scheduler checked with Duration 1 hour, Forever is selected.
CSV config: Recycle EOF is set to True, Stop thread on EOF is set to False. The CSV is having 20 rows and these rows data has been used/fetched multiple times during 40 mints.
--HTTP Sampler
Tried multiple times with different duration, still the same issue. No errors logged in jmeter.log file.
Referred below resource as well:
JMeter ignore Duration time when using Scheduler
Please suggest to make it to work for complete specified duration.
Unfortunately we're not telepathic enough to guess what's wrong without seeing jmeter.log file from the master machine and jmeter-server.log files from the slaves, the answer should be either in these or in the .jtl results file.
Your test configuration looks very good, just check 3 points:
make sure that the OS time is synchronised on all the slaves and the master
Copy your CSV file to all the slaves
None of Stop Thread/Stop Test/Stop Test Now radiobuttons in the Thread Group are checked
Also be informed that according to 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article you should always be using the latest version of JMeter so consider upgrading to JMeter 5.2.1 (or whatever is the latest stable JMeter version available at JMeter Downloads page) on next available opportunity as it might be the case you're suffering from a form of a bug which has been already fixed.
I'm having problem with jmeter while running the test plan. Suddenly my Jmeter starts hanging and appears as a black screen in GUI mode. I was running recording controller with multiple thread groups (4 thread groups). Each thread group with 25 users.
I'm using Jmeter 2.11 (current version). I'm not sure whether it is due to overload or some other reason.

Don't ever use GUI mode for load test. Run JMeter in command-line non-GUI mode as follows
jmeter -n -t /path/to/your/testplan.jmx -l /path/to/testresults.jtl
Also if you have any listeners in your test plan - disable or remove them as well. After test execution you should be able to open testresults.jtl file with the listener of your choice and analyze results, but don't use them during load test.
Make sure that you following Performance Checklist and other recommendations from JMeter Performance and Tuning Tips guide
You have run out of JMeter/JVM memory. You can increase in with environment variables, command line options when you start jmeter, or change some values in jmeter.properties
This page describes how to start jmeter with more memory.
http://jmeter.apache.org/usermanual/get-started.html
One easy way is to set the environment variable before running jmeter:
set JVM_ARGS="-Xms1024m -Xmx1024m"
This will allow your tests to run longer before running out of memory, but if you store results in memory (for instance using View Results Tree listener), you will still run out eventually. For long running tests, or accurate measurement of short running tests, it is better to run in non-GUI mode, and save results to file, instead of memory.
Graphs can still be generated after the run from the saved results using jmeter utilities.
I am trying to load test my app by setting the Start and end time in Scheduler as a variables eg:
Start Time : ${START_TIME}
End Time : ${END_TIME}
bit Jmeter is not allowing to save it.Is it not a configurable option ?
This is what I want to do
jmeter -Jduration=600 -n -t /path/to/your/test/plan.jmx
This will kick of the tests immediately for 10 mins (600s)
Can the start time be configured in such a way that it is always a current time
You can configure it but it has to be a valid Date
If you want to control duration of your test I would recommend the following:
Test Start Time can be set by OS means (cron jobs, scheduled tasks, continuous integration system build plan, etc.)
Test Duration can be set via JMeter Property.
For instance, you want your test to run for 2 hours. In order to achieve this you need to provide the value of "7200" into "Duration" section of thread group. If you put ${__property(duration,,)} or ${__P(duration,)} into "Duration" input of thread group and set this duration=7200 property in i.e. user.properties or jmeter.properties files (they both live under /bin folder of your JMeter installation) or provide it as a command-line argument as
jmeter -Jduration=7200 -n -t /path/to/your/test/plan.jmx -l /path/to/results/file.jtl
The test will run for 2 hours (plus some additional time to gracefully shut down all the test threads).
See Apache JMeter Properties Customization Guide for more details on JMeter Properties use cases.
