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 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
Is there any possibilities to get my below mentioned Graph Results in JMeter test, which is executed in non GUI mode. I can extract its values using csv, but we need to run the test in non GUI mode to get dashboard results also. Any possibilities for this ?
Given you run your JMeter test in command-line non-GUI mode like:
jmeter -n -t test.jmx -l results.jtl
Once test is finished you should be able to open JMeter GUI, add Graph Results listener, locate results.jtl file using "Browse" button and you will see the chart.
Also there is an option to generate some charts in unattended manner using Command-Line Graph Plotting Tool available via JMeter Plugins project, see Automatically generating nice graphs at end of your Load Test with Apache JMeter and JMeter-Plugins guide for details.
I am trying to write web app based on Django to work with test results, do an online monitoring, etc. (kinda dashboard) for load tests which runned in Jmeter console mode (incl. distributive testing).
Maybe you will want to participate in development or so :):

When i tried to convert the LR script into Jmeter using Jmeter latest version 3.2 View results Table doesn't captures all calls , where as Summary Report as well as under Thread group>Recording Controller I can see all the calls.
How does it effects means. If I cannot see the calls in the View Results Tables ,I cannot do correlation, parameterization etc for the missing calls.
Does any one has encountered this wearied issue.
Note: Jmeter V3.1 works perfectly !
Please advise me!
Thanks,
Raj
This is not a bug.
As per the issue that was opened:
https://bz.apache.org/bugzilla/show_bug.cgi?id=61014
Starting with JMeter version 3.2 the number of results in View Results Tree is limited by default to 500 entries.
If you want more entries, you have to set the property:
view.results.tree.max_results
to a higher value, or to "0", if you don't want to impose any limit.
You can set the property in bin/user.properties
But be aware that this involves less responsiveness of JMeter during Load Test.
More info might be found at:
http://jmeter.apache.org/usermanual/component_reference.html#View_Results_Tree
You can try the following steps:
Add "HTTP(s) Test Script Recorder" under the workbench.
Add "View Test Results Tree" under the "HTTP(s) Test Script Recorder".
In the "HTTP(s) Test Script Recorder" config, select the following options: Target Controller: "Workbench > HTTP(s) Test Script Recorder" & Grouping: "Put each group in a new Transaction Controller".
Start the recorder, finish recording, and stop the recorder.
Add a "Thread Group" under the "Test Plan" and you can drag/copy the Transaction controllers to the Test Plan.
Note: The "Grouping" option would really depend on how you would like to configure your transactions however this is a recommended approach during recording.
Let me know if this helps.
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.
I am new to JMeter. I did my first script in JMeter.
My scenario is: clicking a button, i.e. after login, click that button. Thats it. Upto this i have recorded for my script using JMeter.
When i run for single user, it gives proper output for any different user. But when i run with concurrent users (2 or more users with User Parameters pre-processor), it shows error in clicking that button.
I have used View Results Tree as listener to see the results.
In sometimes, it does not show error. So i can't identify the exact reason, why it fails.
Can you please anyone can guide me regarding this?
I am completely new to this JMeter.
Thanks in Advance,
A 500 internal server error indicates jmeter is making the connection to your server and your server is having difficulty processing the request. You should probably look at your server log files to see if there are any errors or exceptions (apache/jetty/etc log file).
Additionally, when you DO actually have an issue with jmeter and you can't seem to figure out what is going on from your listener output, you can view the jmeter.log file created in the directory when jmeter is run from. This usually gives more detailed information regarding failures in jmeter.
