When I am running a simple standalone JMeter script using command line as below
jmeter -n -t your_script.jmx
This generates a CSV file which contains all the data related to the execution.
However, when the same JMeter file executed for a distributed load testing with multiple JMeter Server IP addresses which will simulate the given number of users and runs on the target server, I am not able to get the jmeter.csvfile Generated(But the command runs successfully).
The command I have used for distributed execution is
jmeter -n -t script.jmx -R IP_address1, IP_address2,...
Now, I should get a consolidated jmeter.csv file from this execution. But, I am not getting one.
Same is the case with JMeter API DistributedRunner Class- We are not getting the consolidated jmeter.csv file and reports.
This command:
jmeter -n -t your_script.jmx
does not generate any CSV file, you need to add -l command-line argument and provide desired results file location like:
jmeter -n -t your_script.jmx -l jmeter.csv
The same applies for distributed testing:
jmeter -n -t script.jmx -R IP_address1, IP_address2 -l jmeter.csv
If you provide -l command-line argument but still not getting any results most probably your script execution fails on remote slaves somewhere somehow. Follow the below checklist in order to get to the bottom of the script failure:
Inspect jmeter.log file on master machine and jmeter-server.log on the remote slaves, if something goes wrong - most probably you will find the cause in log files
Make sure that JRE version is the same on master and the slaves
Make sure that JMeter version is the same on master and the slaves, it's recommended to use the latest JMeter version where possible
If the test relies on any of the JMeter Plugins - make to install them all onto all slave machines. The plugins can be installed using JMeter Plugins Manager
If your test is using CSV Data Set Config - you will need to copy the CSV file to all slaves manually
If your test needs any additional JMeter Properties you will need to supply the properties via -J or -D command-line arguments on all the machines or via -G command-line arugment on the master

Context: I am running JMeter load test on a distributed load system with 1:2 master slave ratio, with the following command:
jmeter -n -t "home/jmeterscripts/EventGridScript.jmx" -R slave1:1099,slave2:1099 -l "home/jmeterscripts/Result.csv" -e -o "home/jmeterscripts/HTMLReports"
Will the result report to the same report.html because I am getting error of Result.csv presence from slave2 while reporting? how to handle it this, didn't find similar post.
You're getting this message because home/jmeterscripts/Result.csv is present already, if you don't need the results file from the previous run add -f command-line argument to your command line:
jmeter -n -t -"home/jmeterscripts/EventGridScript.jmx" -R slave1:1099,slave2:1099 -f -l "home/jmeterscripts/Result.csv" -e -o "home/jmeterscripts/HTMLReports"
-f, --forceDeleteResultFile
force delete existing results files and web report folder if present before starting the test
The results are not being stored on slaves, the slaves send test metrics to the master so the master collects the statistics from all the slaves so no matter how many slaves you have you always get a single .jtl results file and a single HTML Reporting Dashboard.

I have a single master and 5 slave agents. I am starting my test using the command line option from the master by specifying the slave machines using the -R option.
$JMETER_HOME/current/bin/jmeter -n -t test.jmx -R host1,host2 -l testresult.jtl -Jthreads=$THREADS -Jrampup=$RAMPUP -Jtestduration=$TESTDURATION -JENV=$ENV -e -o ./testreport
I see that the new values that are passed in the command line using the -J switch are not getting applied when the test plan is transferred to the slave machines. Slaves are using only the hardcoded values in the JMX.
According to Jmeter Doc on Overriding Properties Via The Command Line
-J[prop_name]=[value]
defines a local JMeter property.
-G[prop_name]=[value]
defines a JMeter property to be sent to all remote servers.
So, you need to use -G flag for Jmeter property to be sent to all remote servers.
We have a highly parameterized JMeter job, and we define all those parameters (things like number of users and length of simulation) in a Java properties file that we specify on the command line
jmeter -n -t myscript.jmx -p 500users.props
but when we tried to distribute this over several machines:
jmeter -n -t myscript.jmx -p 500users.props -Rmachine1,machine2,machine3
those machines did not see the value specified in the properties file. How do you configure your JMeter tests in a distributed scenario?
Evidently you need to use the -G flag to get things to other servers.
jmeter -n -t myscript.jmx -G500users.props -Rmachine1,machine2,machine3
I'm running JMeter through jenkins for performance testing using the command line options. I already write to one jtl file when I do the command, such as:
java -jar path to Jmeter -n -t jmx file -l log file
I would like to also put the results into another log file stored in another location, but I can't get it to work by putting another path after the -l command or putting in a second -l. Is there anyway to do this simply?
Thanks
Check these options. you should use the option '-j'. It works fine for me.
-n This specifies JMeter is to run in non-gui mode
-t [name of JMX file that contains the Test Plan].
-l [name of JTL file to log sample results to].
-j [name of JMeter run log file].
-r Run the test in the servers specified by the JMeter property "remote_hosts"
-R [list of remote servers] Run the test in the specified remote servers
I am trying to pass the Thread count parameter to JMeter in CLI mode. This works perfectly well when the script is running locally. I need to run the script remotely, so I am using the -r switch so that the JMeter script runs on the configured remote clients.
This is my cli command:
jmeter -n -t "C:\ScriptLocation\Sanity_WebV2_Prod.jmx" -r -l c:\CSV\log.jtl -Jusers=4
The intention is that the above command should run the script on remote machine for 4 users (threads). Number of Threads in the thread properties is set to ${__P(users)}.
But the script is actually running only for 1 user (the default values) not for 4 users that is passed as the parameter.
When executed the above mentioned cli command w/o -r switch i.e script executing on the Local machine it is working perfectly fine i.e for 4 users.
Need help in solving this problem. Thanks
Try to use -Gusers option instead of -Jusers one:
-D[prop_name]=[value] - defines a java system property value.
-J[prop name]=[value] - defines a local JMeter property.
-G[prop name]=[value] - defines a JMeter property to be sent to all remote servers.
