Straight and short, i want jmeter to stop writing any output in the .csv results file.
I've heard that preventing the creation of the file is not possible however we can set the results file configuration properties to decide what values to output so basically i went over all those properties, i did read them all and i set the ones that i could set to false to false, the ones that i could set to none to none and the ones that i could set to their default values to their default values, in theory the file shouldn't print anything and remain at 0kbs, however this is not the case the file still grows in size and it is printing a zero every line like these:
0
0
0
0
and this is how i have my properties in the user.properties file
jmeter.save.saveservice.output_format=csv
jmeter.save.saveservice.assertion_results_failure_message=false
jmeter.save.saveservice.assertion_results=none
jmeter.save.saveservice.data_type=false
jmeter.save.saveservice.label=false
jmeter.save.saveservice.response_code=false
jmeter.save.saveservice.response_data=false
jmeter.save.saveservice.response_data.on_error=false
jmeter.save.saveservice.response_message=false
jmeter.save.saveservice.successful=false
jmeter.save.saveservice.thread_name=false
jmeter.save.saveservice.time=false
jmeter.save.saveservice.subresults=false
jmeter.save.saveservice.assertions=false
jmeter.save.saveservice.latency=false
jmeter.save.saveservice.connect_time=false
jmeter.save.saveservice.samplerData=false
jmeter.save.saveservice.responseHeaders=false
jmeter.save.saveservice.requestHeaders=false
jmeter.save.saveservice.encoding=false
jmeter.save.saveservice.bytes=false
jmeter.save.saveservice.url=false
jmeter.save.saveservice.filename=false
jmeter.save.saveservice.hostname=false
jmeter.save.saveservice.thread_counts=false
jmeter.save.saveservice.sample_count=false
jmeter.save.saveservice.idle_time=false
jmeter.save.saveservice.timestamp_format=none
jmeter.save.saveservice.default_delimiter=,
jmeter.save.saveservice.print_field_names=false
jmeter.save.saveservice.xml_pi=
jmeter.save.saveservice.base_prefix=~/
jmeter.save.saveservice.autoflush=false
Where is that 0 coming from? is it impossible?
If you don't want the results file just don't provide its location, i.e. omit this -l bit when you launch JMeter test in command-line non-GUI mode:
jmeter -n -t test.jmx
The above command will trigger the test execution but no .jtl results file will be created.
Not sure why you want to create a .csv file when your not storing anything into it.
Maybe just don't give any file name here

I am using following command to generate HTML dashboard:
jmeter -g C:/Users/E01659/Desktop/feb28/feb28_10_3600.csv -o C:/Users/E01659/Downloads/apache-jmeter-5.1/bin/sonali/
Following error is coming: File
'C:\Users\E01659\Desktop\feb28\feb28_10_3600.csv' does not contain the
field names header, ensure the jmeter.save.saveservice.* properties
are the same as when the CSV file was created or the file may be read
incorrectly when generating report An error occurred: Mismatch between
expected number of columns:17 and columns in CSV file:11, check your
jmeter.save.saveservice.* configuration or check line is complete
errorlevel=1
From the error message, it is clear that - CSV file created earlier don't have the header as the first line. When you want to create the APDEX Dashboard from CSV file, JMeter expects that files are created with correct Save Service Configuration. You can change Result file config which are present in jmeter.propertes file.
You may need to change the line as below, so that file created has the headers name as required
jmeter.save.saveservice.label = true
The command you're using is correct, the reason of failure is mismatch of the .jtl file contents and what JMeter expects it to be.
If you got this feb28_10_3600.csv file from execution on another JMeter installation - make sure that JMeter's result save configuration on the machine where you're trying to generate the report is identical to the JMeter installation where JMeter was running.
Inspect the associated JMeter properties and amend them to for 100% match, once done you should be able to normally generate the dashboard.
If you still experience the differences update your question with first 2-3 lines of your .jtl results file.
You are receiving this error (most likely) due to a corrupt line at the end of your file. Just execute a 'tail ' to see the last few lines. Most likely, your last line is missing columns due to an abrupt stop in the test. Once you delete the problematic line, you should be able to generate the HTML report.
I'm having next structure of TG in Jmeter:
So I have variable LB_LEVEL and 100 threads. It's value for every user may be different (from 1lv to 23lv e.g.)
I try to find a way to make some visual report with this variable, simply I have to show how users were casted to different levels.
It may be csv, or smh. Ideal table of my dream looks like this:
Googling still brings me some foam, so I need a small idea or kick to correct direction.
Thank you!
Add the next lines to user.properties file:
sample_variables=LB_LEVEL
jmeter.reportgenerator.graph.custom_testGraph.classname=org.apache.jmeter.report.processor.graph.impl.CustomGraphConsumer
jmeter.reportgenerator.graph.custom_testGraph.title=LB LEVEL
jmeter.reportgenerator.graph.custom_testGraph.property.set_Y_Axis=LB LEVEL
jmeter.reportgenerator.graph.custom_testGraph.set_X_Axis=Over Time
jmeter.reportgenerator.graph.custom_testGraph.property.set_granularity=60000
jmeter.reportgenerator.graph.custom_testGraph.property.set_Sample_Variable_Name=LB_LEVEL
jmeter.reportgenerator.graph.custom_testGraph.property.set_Content_Message=LB_LEVEL:
sample_variables is a special property which saves custom variable(s) into .jtl results file
Restart JMeter to pick the properties up
Run your JMeter test in command-line non-GUI mode and generate the HTML Reporting Dash board as:
jmeter -n -t <test JMX file> -l <test log file> -e -o <Path to output folder>
Open <Path to output folder>/index.html file with your favourite browser - you will see plotted LB_LEVEL values along with other tables and charts.
If for some reason it doesn't fit your needs you can consider using Flexible File Writer to store the metrics of your choice into a file, in your case they would be grpThreads and variable#0
I am fetching data from the CSV file and giving as input to my Request.How can I save all the request in the same file when I run a test for an hour.
One more requirement is, if the result is success then I have to write that data I have used from the CSV into another file so that we can have only the data which is working in an separate file.
Please suggest
The best way would be using JMeter's built-in Sample Variables property.
Add the next line to user.properties file:
sample_variables=foo
Replace foo with the variable name you're getting from the CSV file
Next time you run your JMeter test in command-line non-GUI mode like:
jmeter -n -t test.jmx -l result.csv
your result.csv file will have an extra column called foo and having the foo variable value for each and every request. You will be also able to determine which data caused the failure by looking into "success" column
Is there a way to access Jmeter variable data even after tests are run?
This is what i am looking for:
Run a test, store the data in a variable (test finishes in 2 mins)
Idle for 15 mins
Run another test
i want the variable in step 3, Without running step1 again.
The most straightforward choice is saving the variable(s) you need into JMeter's .jtl results file using Sample Variables property. In order to "tell" JMeter to save certain variable value you need to add the next line to user.properties file:
sample_variables=your_variable_name
Alternatively you can pass this property value using -J command-line argument
jmeter -Jsample_variables=your_variable_name -n -t ....
Once done you should see an extra column in the .jtl results file holding your variable values. You should be able to access these values using i.e. CSV Data Set Config.
See Configuring JMeter user manual chapter for more details.
Variables are per test. You need to use a resource as file.
Use propert file to save and load variable as follows:
Start jmeter with property file as -q my.properties
On your test check if property exists if exists skip step 1
If not - do step 1 and then add the variable to property file line as propName=propValue
See example
In my Jmeter test, I am able to use REGEX Extraction, After extraction I want to write the value of the REGEX variable into a file
I found a workaround as using beanshell as mentioned here https://stackoverflow.com/a/15159521/4556894
Is there any clean way of doing it, May be some inbuilt features, which I am not aware of
It is possible to write variable values into JMeter .jtl results file. There is a JMeter Property called sample_variables
Optional list of JMeter variable names whose values are to be saved in the result data files.
Use commas to separate the names.For example:
sample_variables=SESSION_ID,REFERENCE
So if you run JMeter in command-line non-GUI mode as follows:
jmeter -Jsample_variables=myVariable -n -t /path/to/your/testplan.jmx -l /path/to/testresults.jtl
You'll get the output like
timeStamp,elapsed,label,responseCode,responseMessage,threadName,dataType,success,bytes,grpThreads,allThreads,Latency,"myVariable"
1425978657207,368,HTTP Request,200,OK,Thread Group 1-1,text,true,1591,1,1,367,YOUR_VARIABLE_VALUE
In above example column names are given for reference, they are not included into csv results file by default. This behavior is controllable via jmeter.save.saveservice.print_field_names property, set it to "true" to get column names printed along with results data.
You can also set sample_variables property value in user.properties file which lives under /bin folder of your JMeter installation or uncomment it in jmeter.properties file (same location)
