I'm trying to run a robustness test using jmeter through Jenkins and need to view the summary of the test in progress. When running the test locally using GUI mode, I can see the an agregate report of my test as it's running, is the same thing possible while I'm running in a nongui mode? I tried to change the summariser within properties file:
**#----------------------------------------------------------
# Summariser - Generate Summary Results - configuration (mainly applies to non-GUI mode)
#----------------------------------------------------------
# Define the following property to automatically start a summariser with that name
# (applies to non-GUI mode only)
summariser.name=summary
#
# interval between summaries (in seconds) default 3 minutes
summariser.interval=180
#
# Write messages to log file
summariser.log=true
#
# Write messages to System.out
summariser.out=true**
and also enabled logging information but I still don't see any summary. Even if I can get a constant logger within stdout then I can atleast view this within the console output from Jenkins, but currently I am not able to produce this. Does anyone know how to configure this?
With JMeter 2.11, summariser is enabled by default in Non GUI mode, so you should have what you need.
Although what you show seems right except for :
summariser.out=true**
Which should be:
summariser.out=true
Console status logger plugin can solve your task. See here:http://jmeter-plugins.org/wiki/ConsoleStatusLogger/

I have 3 listeners setup to write to a file SummaryReport, AggregateReport, and ViewResultsInTable. I am on a MacBook os Big Sur 11.5.2 and JMeter 5.4.1. Weirdly enough, I get the ViewResultsInTable data in both the SummaryReport.csv and AggregateReport.csv. While I am writing the Test Plan, it is easy to recover because the UI Reports are correct. However, when I want to move to the real test and run it from the command line, I won't be able to recover.
Is there any way to clear that up?
Saving and reading the test results are generic in all Listeners. Hence you will get identical test results in all the files.
If you didn't click "Configure" button and changed the metrics to store you will get the same files no matter which listener(s) you use, you just ended up with 3 identical files (plus the .jtl file if you're running your test in command-line non-GUI mode)
In case of Summary Report and Aggregate Report listeners all the metrics you're seeing are calculated from the individual Sample Result entries so if you open the .jtl results file after your non-GUI test execution finishes you will see the calculated aggregate metrics.
In general you should be using Listeners only for tests development and, it doesn't make a lot of sense to add Listeners for the test execution, they don't add any value, just consume valuable resources. So disable/remove all the listeners, you should be able to get all you need from the aforementioned .jtl results file.
If you want to see the output of Aggregate Report and/or Summary Report listeners without opening JMeter GUI - you can generate them from the .jtl results file using JMeter Plugins Command Line Tool
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
I have a JMeter test plan which is running two thread groups, with each thread group containing a controller and HTTP cookie manager. The controller is a custom controller, but I don't think this should affect JMeter's output.
Outside the two thread groups, I have an Aggregate Report component. Here is a screenshot of my TestPlan:
If I run the test in GUI mode, as you would expect, the Aggregate Report creates an.... aggregate report. That is, the results are aggregated on my test/sample labels, and I get one row for each test, and a range of attributes, as below:
I also have configured this Aggregate Report component to output to a file, by entering a filename in the "Filename" section, and pressing the "Configure" button and checking the attributes I'd like to be output (I've kept it simple for now with just the label, elapsed time and response code).
When I run my test from non-gui mode, this output file is the only way to view the results. However, the output file is rather useless and it does not aggregate the results, but instead gives me output similar to the usual jtl output, i.e. it doesn't aggregate the results at all. Pretty useless. Here is the top few lines of my output file, you can clearly see they are not aggregated:
778,HRLogin,200
426,HRLogin,200
784,HRLogin,200
...
So, the obvious question, am I doing something wrong here? Why is my aggregate report output not an aggregate report? Surely JMeter has a way for producing aggregate output in non-gui mode, without me adding any plug-in or extensions. For the record I need to script this process at some point, so opening a JTL in gui mode is not acceptable, I need this entire process to occur within non-gui JMeter and scripts.
Thanks!
The values you see in the Aggregate Report GUI are calculated from the raw data which is stored in the .jtl file.
If you need to make the process unattended, depending on metrics you need to obtain here are the options:
Since JMeter 3.0 there is a HTML Reporting Dashboard which contains some tables and charts. You can either generate a dashboard from existing results file or make it a part of your test. See Generating Reports chapter for the relevant commands.
Another way to get basic HTML report is running JMeter via Ant Task or Maven Plugin - in both cases you'll get test output like:
See Five Ways To Launch a JMeter Test without Using the JMeter GUI guide for details on configuring a JMeter test run through Ant and/or Maven. There is a number of pre-defined .xsl stylesheets in "extras" folder, you can take whatever you like and customize if needed.
You can also consider running your JMeter test via Taurus tool, it provides interactive console and web-based reporting and has few more options to export test results.
Need a help in jmeter. When we run jmeter from GUI mode, we can see the instant results in UI and that gets auto refreshed in milliseconds or lesser.
But when I run jmeter from command line , in non GUI mode it still creates the result file and I can view it by another jmeter and with the adding an aggregate report listener to it. It opens the results with a pop up alert message but does not refresh it. For getting the updated results , need to browse and open it again .
So is there any way/plugin to open the file to view with auto refreshed as we can view while running in GUI mode.
Thanks
It is not recommended to use listeners during test run, even if it is done via another instance of JMeter. Wait for the test to finish and then perform the analysis.
If for some reason looking into interim stats is absolutely required I would recommend running your JMeter test using Taurus tool as a wrapper, you'll be able to see some statistics and graphs this way:
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.
