Is there a way to get the debug sampler results while running jmeter in non-gui mode? More simply I am looking for a way to log all the variable substitutions that happen while the test is run. I tried enabling and disabling debug logs for the available packages, but am still not able to get the substitutions.
Here are the options:
sample_variables property. For instance if you need to see values for variables foo and bar add the next line to user.properties file which lives under /bin folder of your JMeter installation:
sample_variables=foo,bar
and aforementioned variables values will be added as separate columns to .jtl results file. See Apache JMeter Properties Customization Guide for more information on JMeter properties and ways of working with them
You can print something to jmeter.log file via __log() or __logn() functions

I'm trying out taurus to run some existing jmeter scripts, setting various properties to local values.
I can use the -gui mode to load the modified script in the jmeter GUI and debug. However, I can't update this and replace the original file because Taurus has added two jtl data writers. I can suppress "Errors Writer" with e.g. -o execution.0.write-xml-jtl=none, but I can't see a way to suppress "KPI Writer". It's also possible further undesirable modifications have been made.
Is there a way to launch the GUI so that I can edit the original file, using the properties from the Taurus yaml file?
You cannot run the original jmeter scripts through bzt however it is possible to manipulate few properties of the newly generated jmx file through the yml file. Modified jmx is a copy of original script where two Listeners (errors and kpi) and variables from the yml.
It now depends on what exactly are you looking to change?
I add several components for debugging as Debug Sampler, View Results Tree and JSR223 Sampler that are useful in GUI mode, but I want it to be ignored when running load test,
Is there such option of executing Sampler/Listener only in GUI mode and not in command line/"load" mode?
I am not sure that this is the exact answer you are looking for but still let me try. We know that JMeter script is nothing but xml in disguise and structure look like this.
So for every Jmeter component, there is enable property which needs to be true so that it will get executed as part of JMeter Test plan. Now if we can change this some properties which can be passed as parameter then we can make them disable at the run time.
Change in jmx will be reflected like this...
If you run this script in Non GUI mode with additional property passed as parameter, we essentially achieve what we want.
jmeter -n -t .\ExcludeJMeterComponent.jmx -l result.CSV -e -o "Output" -DenabledDebugComponents=false
Issue with this approach is, if you load this script again in JMeter, these values, manually edited jmx going to go away/get override with your next save but if you are using any version control system to keep track of your jmx script [which you must be doing] it will be very easy to add this changes in the script again in no time.
I will post this with more details once my blog is set up.
Found a workaround, to send in CLI JMeter property as -JignoreFirstSampler
Add If Controller as a parent of samplers to exclude checking if property is defined
${__isPropDefined(ignoreFirstSampler)}
The __isPropDefined function returns true if property exists or false if not.
How to exclude the debug sample from the summary report?
I tried removing but for some reason it does not work the process below, so is there a way to exclude from the results?
Debug Sampler just used to print variables for debugging
Debug PostProcessor creates a subSample with the details of the previous Sampler properties, JMeter variables, properties and/or System Properties.
You can print variable(s) using JSR223 Pre/Post Processor using
log.info(vars.get("varName"));
log.info(props.get("propName"));
If you need debugging only in specific GUI testing you can also add Debug Sampler under If Condition which will not work unless you manually set it to true.
You can use Filter Results Tool JMeter Plugin like:
FilterResults.bat --input-file your_existing_file.jtl --output-file result_without_debug_samplers.jtl --exclude-labels "Debug Sampler"
The above command line will parse existing results file and remove any Debug Sampler instances from it.
Filter Results Tool plugin can be installed using JMeter Plugins Manager
Upon installation you will find FilterResults.bat and FilterResults.sh scripts under JMeter's "bin" folder
I know that we can export/save results of a listner in csv or xml format.
But what i want is to save the listner result once the script has been run.
There seems to be no way of doing this. currently giving a file path in a listner will work only before the execution begins not after it is over.
As per JMeter Performance and Tuning Tips guide it is recommended:
To use non-GUI mode for tests execution
To disable all the listeners during the test run
On test completion you should be able to open .jtl results file by the listener of your choice.
If you need to store some specific data required by this or that listener, take a look into jmeter.properties file (lives in /bin folder of your JMeter installation) and amend properties having "jmeter.save.saveservice." prefix according to your plans.
Perhaps Automatically generating nice graphs at end of your Load Test with Apache JMeter and JMeter-Plugins guide can also help.
I am running Jmeter in non-gui mode. When I load the resulting.jtl file in jmeter I can see sample result but it does not give me sampler request and response data. Help appreciated!
By default sampler request and response data are not stored in the .jtl file. To override this behavior you need to "tell" JMeter to store the data. To do so locate the following properties in jmeter.properties file which lives under /bin folder of your JMeter installation, uncomment and change to "true" values of the following:
#jmeter.save.saveservice.samplerData=false
#jmeter.save.saveservice.response_data=false
Alternatively you can pass these properties during command-line execution via -J key as follows:
jmeter -Jjmeter.save.saveservice.samplerData=true -Jjmeter.save.saveservice.response_data=true -n -t /path/to/your/script.jmx -l /path/to/results/file.jtl
See Apache JMeter Properties Customization Guide for more information on dealing with JMeter properties.
Also be aware of the fact that storing requests and especially responses will have negative impact on your load generator(s) performance.
