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.

I would like to pass jtl file name over command line arguments. commanline lookslike this:
jmeter -J JTL=%JTLFILE% -t Metasuche.jmx
In Script I am using ${__P(JTL)}. If i am starting jmeter like this:
jmeter -J JTL=%JTLFILE% -t Metasuche.jmx
and
jmeter -J JTL=%JTLFILE% -t Metasuche.jmx -n
It works as expected and jtl file is created in a file as passed in arguments. But if I am starts Jmeter with:
jmeter -J JTL=%JTLFILE% -t Metasuche.jmx and -n -r
then my JTL values are landing in a new File ${__P(JTL)} in current directory.
How should I tell jmeter to use command line arguments in local and remote executions?
If you want to pass the properties to the remove machines via command-line argument you should be using -G instead of -J
As per Overriding Properties Via The Command Line
-G[prop_name]=[value]
defines a JMeter property to be sent to all remote servers.
-G[propertyfile]
defines a file containing JMeter properties to be sent to all remote servers.

How to Perform Distributed Testing in JMeter
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
In my test environment i want to start the jmeter slaves from master before the test and shutdown the slaves after the test. How to do these from jmeter master? The test environment is in CentOS.
Add to your command line :
-X
Example:
jmeter -n -t testplan.jmx -r -X
-X means to exit the servers at the end of the test.
See:
http://jmeter.apache.org/usermanual/get-started.html#options
I would suggest using one of the following approaches:
OS Process Sampler in combination with ssh command (or plink if master is on Windows)
SSH Sampler (available via plugin)
See How to Run External Commands and Programs Locally and Remotely from JMeter guide for details.
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 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.
