unable to Jmeter in distribution load, getting below error please help am using jmter v3.0.20160606
Changing to JMeter home directory
Could not find ApacheJmetercore.jar
Trying JMETERHOME=
Found ApacheJMeter_core.jar
This is expected and normal, now you need to launch a JMeter Master like:
jmeter -R xxxxx -n -t test.jmx -l result.jtl
Replace xxxxx with IP address or hostname of the machine where you launched Slave node, you should see something like:
Starting the test on host xxxxx # current date and time

I am executing JMeter remote testing with 1 master machine (192.168.0.1) and with 7 slave machines with 3 VMs (192.168.0.2 to 192.168.0.4) on a network interface and 4 other VMs (192.168.0.5 to 192.168.0.8) are in a different network interface.
My JMeter script is located at Master machine - 192.168.0.1
I tried to execute my test with the following command
./jmeter -n -t /home/lup01/Document/LuP2021/ITonICE_Lasttest_InfluxDebug_09032021.jmx -l /home/lup01/Document/LuP2021/LuP2021_LastTest_001_14-10-2021_7VMs.jtl -R 192.168.100.2,192.168.100.3,192.168.100.4 -Djava.rmi.server.hostname=192.168.100.6,192.168.100.7,192.168.100.8,192.168.100.9
However, the test never started. the screen just hung and after 15 minutes i had to stop the test. I did the sample run only with 3 threads.
On course of debugging, i also checked that, when i executed the test with
./jmeter -n -t /home/lup01/Document/LuP2021/ITonICE_Lasttest_InfluxDebug_09032021.jmx -l /home/lup01/Document/LuP2021/LuP2021_LastTest_001_14-10-2021_7VMs.jtl -R 192.168.100.2,192.168.100.3,192.168.100.4
the test was running fine with 3 VMs which are on the same interface as the master machine
However, when i executed the 2nd part
./jmeter -n -t /home/lup01/Dokumente/LuP2021/ITonICE_Lasttest_InfluxDebug_09032021.jmx -l /home/lup01/Dokumente/LuP2021/LuP2021_LastTest_001_14-10-2021_7VMs.jtl -Djava.rmi.server.hostname=192.168.100.6,192.168.100.7,192.168.100.8,192.168.100.9
the test got executed but the load was generated only on the master machine (192.168.0.1). i validated this by printing the host name in the result file.
Can someone please guide me what changes i need to do to get the test running successfully and the load being generated at the slave machines 192.168.100.6 to 192.168.100.9?
JMeter Master machine doesn't generate any load, it only reads .jmx script, transfers it to slaves and collects results.
It doesn't make sense to run more than 1 JMeter process on 1 machine, it doesn't provide any benefit and just consumes resources, if you have only one machine - run a single JMeter process, just make sure to follow JMeter Best Practices and properly tune this JMeter instance for high throughput testing
If this is some form of an experiment and you have to run multiple JMeter processes on a single host and would like to bind different JMeter instances to different network interfaces - you can do it via "Advanced" tab of the HTTP Request sampler (or HTTP Request Defaults if you have more than one sampler) like it's described in Using IP Spoofing to Simulate Requests from Different IP Addresses with JMeter
I have a requirement to run 4000 users. I just wanted to run that using Non-GUI. How can we create 8 instances with 500 users each using Non-GUI mode in Jmeter. Suggest the possible scenario with an example.
Get 9 machines somewhere somehow
Install Java 8+ (it's the per-requisite to run JMeter 5.4)
Install JMeter onto all machines. If you plan to use JMeter Plugins make sure that all the plugins are installed on all machines
If your test depends on external files or libraries - make sure that all the libraries and/or files are copied to the JMeter Machines
If you plan to use secure communication between master and slaves follow Setting Up SSL JMeter Documentation chapter, if not - add the next line to user.properties files on all machines:
server.rmi.ssl.disable=true
Run jmeter-server on 8 machines which will be acting as slaves
Add the next line to user.properties on the master machine
remote_hosts=ip_address_of_slave1,ip_address_of_slave_2, etc.
Make sure that the machines are on the same subnet and there is no firewall blocking connections between them
Run your test as:
jmeter -r -n -t /path/to/your/test.jmx -l /path/to/results.jtl
When the test finishes analyze your results by using Listeners or generating HTML Reporting Dashboard

How to Perform Distributed Testing in JMeter
I am trying to launch my jmeter tests in a remote machine as i will be running bulk users on a .jmx file (Approx 200 000 threads). I have a remote machine where i have downloaded jmeter and saved the folder in desktop. and in command prompt i have a command
Desktop\apache-jmeter-4.0\bin>jmeter-server -n
Could not find ApacheJmeter_core.jar ...
... Trying JMETER_HOME=..
Found ApacheJMeter_core.jar
Created remote object: <Have a message saying the server is up and running>
Now in jenkins i have a command
export JAVA_HOME=/java/1.8.0.65
bin//jmeter -n -R <Remote HOst IP> -t file.jmx -l result.jtl -e -o/resultfolder
When i trigger the job in jenkins i am getting
Configuring remote engine: <Remote machine IP>
Exception creating connection to: <Remote machine IP>; nested exception is:
java.io.FileNotFoundException: rmi_keystore.jks (No such file or directory)
Failed to configure <Remote machine IP>
Stopping remote engines
Remote engines have been stopped
Error in NonGUIDriver java.lang.RuntimeException: Following remote engines could not be configured:<Remote machine IP>
I have a rmi keystore file created in remote machine.
You need to launch create-rmi-keystore.sh script on all machines and make sure that the configuration is the same, this way communication between JMeter master and slaves will be secure.
More information: Remote Testing: Setting Up SSL
If you don't want the communication between the master and slaves to be secure - you can amend the command line to:
jmeter -Jserver.rmi.ssl.disable=true -n -R <Remote HOst IP> -t file.jmx -l result.jtl -e -o/resultfolder
or add the next line to user.properties file on all hosts to make the change permanent:
server.rmi.ssl.disable=true
JMeter restart will be required to pick the property up. See Configuring JMeter user manual chapter for more information.
Depending on your test nature 1 slave might be not enough to simulate 200k threads so make sure you're following recommendations from the 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article and keeping an eye on JMeter engines health using built-in OS tools or JMeter PerfMon Plugin as if JMeter will not be able to send requests fast enough - you will get lower throughput/higher response times even if your application is not overloaded.
I have a requirement to do load test on server which runs behind a proxy. We are using shell script for performing load test(16 concurrent calls).
Please advice if I can port those script to JMeter to do load test behind proxy.
Yes, you can, check out Using JMeter behind a proxy chapter of the JMeter User Manual, the options are in:
Use -H and -P command-line arguments like:
jmeter -H your_proxy_host -P your_proxy_port -n -t test.jmx -l result.jtl
Use http.proxyHost and http.proxyPort Java System properties like:
jmeter -Dhttp.proxyHost=your_proxy_host -Dhttp.proxyPort=your_proxy_port -n -t test.jmx -l result.jtl
You can make the changes "permanent" by adding the next lines to system.properties file (lives in "bin" folder of your JMeter installation)
http.proxyHost=your_proxy_host
http.proxyPort=your_proxy_port
JMeter restart will be required to pick the properties up
For more information on points 2 and 3 see Configuring JMeter and Apache JMeter Properties Customization Guide
How do you know that your proxy will not become the bottleneck for your testing efforts? The least scale-able item in the path will govern the perceived performance of your clients.
Please give me solution for the below error.
Could not find ApacheJmeter_core.jar ... ... Trying JMETER_HOME=.. Found ApacheJMeter_core.jar Created remote object: UnicastServerRef [liveRef: [endpoint:192.168.8.108:50019 ,objID:[-30cb105c:15ca098204b:-7fff, 5736149660821635846]]]
I tried the below way also, am not able to launch
"I just hard coded the path in my jmeter_server.bat."
Am doing testing now.. if any one knows please update here.
This is not an error at all, it means that you successfully launched a JMeter slave which is now waiting for a command from the JMeter master.
So now you need to start JMeter Master using one of the following approaches:
Pass slave IP address via -R command-line argument like:
jmeter -R 192.168.8.108 -n -t test.jmx -l result.jtl
Define remote_hosts JMeter Property by adding the next line to user.properties file on JMeter Master node:
remote_hosts=192.168.8.108

Apache JMeter Properties Customization Guide
If you need just to open JMeter GUI you will need to launch jmeter.bat script or alternatively directly call java from JMeter's "bin" folder like:
java -jar ApacheJMeter.jar
