Distributed Load Testing with JMeter (2023)

Distributed Testing with JMeter

When one JMeter client is not able to offer amount of threads required for load testing then distributed testing is used. In distributed testing -

  • One instance of JMeter client can control number of JMeter instances and collect data from them

  • Test plan does not need to be copied to each server, the client sends it to all servers

note - JMeter will run all the threads on all the servers, hence 100 threads on 5 JMeter server would pump 500 threads in total.

If many server instances are used, the client JMeter can become overloaded and so the client network connection. This has been improved in latest versions of JMeter by switching to Stripped modes, but you should always check that your client is not overloaded

When Client (master) and Server (slave) nodes are on same network (no SSH required)

Configure Client Node

Herein client is referred as the machine controlling test execution on other JMeter nodes. This is also referred as “master node” since it controls the test execution while “server Node” are referred as “slave node” since they execute the actual test

Add Server IP to Client Properties file

Edit property - /bin/jmeter.properties in client JMeter machine, find property “remote_hosts” and add value of JMeter servers IP address. Multiple servers can be added comma-delimited.

A more convenient way to specify remote host is from command line. Use -R command line to specify which remote host to use (example described below).

Specify client RMI port

Specify client.rmi.localport in jmeter.properties file (for example - client.rmi.localport=25000). This is the port on which the local JMeter instance will listen for the Remote Method Invocation (i.e. RMI connections) from the slave nodes. Results would be sent to client from slave nodes on this port

Configure Server Nodes

      • Server nodes should be running same version of JMeter and java as client
      • Test datafiles are not sent across by client, hence they should be available in appropriate directory in each server. You can keep test data file in /bin folder in each JMeter server. It gets you rid of specifying full qualified path of test data file on each server instance.
      • To use different values for properties use corresponding values for user.properties and system.properties on each server
      • server.rmi.localport- By default, RMI uses a dynamic port for the JMeter server engine. This may cause issues with firewalls, so with versions of JMeter after 2.3.2 you can define the JMeter property server.rmi.localport to control this port number. To use a specific port for the JMeter server engine, define server.rmi.localport property before starting the server

Start Server

JMeter server component is available in following directory -

    • unix/mac - JMETER_HOME/bin/jmeter-server

    • Windows - JMETER_HOME/bin/jmeter-server.bat

and start server as -

unix/mac -

./jmeter-server -Djava.rmi.server.hostname=

windows -

jmeter-server.bat -Djava.rmi.server.hostname=

java.rmi.server.hostname is specified when starting the server, else you may end up with “loopback address” error.

On starting server you would receive message like -

Created remote object: UnicastServerRef [liveRef: [endpoint:[](local),objID:[-1c51de21:14fd1765827:-7fff, 7690653623616494857]]]

Herein endpoint is IP - IP address of server node) with port 60000 (this is server.rmi.localport specified during server node configuration)

Note that you would have to chmod +x on /jmeter-server and /jmeter-server files before you can start jmeter-server file on unix

There can be only one jmeter server on each node unless different RMI ports are used

Check Configuration

Start JMeter client > Remote Start and Remote Stop should contain the client set in properties file -

Distributed Load Testing with JMeter (2)

Start JMeter in non GUI mode

Start test on remote server in non GUI mode as -

jmeter -n -t script.jmx -r

Herein flag -r is to Start remote servers (as defined in remote_hosts property on the master no). Hence this command will start test on remote_hosts

(Video) Distributed Load testing - JMeter Tutorial 21

As specified earlier, a more convenient way to execute tests on remote server is to specify server from command line as following -

jmeter -n -t script.jmx -R server1,server2...

If you want to exit remote server after test is over then use flag -X as following -

jmeter -n -t script.jmx -R server1,server2 -X

When Client (master) and Server (slave) nodes are on different networks (SSH required)

When running test from remote server machines (i.e. aws or google cloud), we need to establish ssh tunneling to make servers available to jmeter client machine. Herein communication between jmeter client and servers is established using JMeter connection and Remote Method Invocation (RMI).

JMeter connection is started by JMeter client (master node) while TCP connection for RMI is started by both JMeter client (master node) and servers (slave node). Hence it results in creation of three connections -

Distributed Load Testing with JMeter (3)

We will use ssh port forwarding (or ssh tunneling) to establish connection b/w JMeter client and server. We will use the localhost address and forward certain ports.

As illustrated above, two connections are required from “L”ocal JMeter client to remote server while one connection is required from “R”emote JMeter server(s) to local JMeter client. Hence we create three tunnels, two out going (“L”ocal JMeter client to remote servers) and one incoming (“R”emote JMeter server to local client)

Following command will set up forwarding on three ports -

ssh -L 24001: \

-R 25000: \

-L 26001: -N -f <username>@<server>

Distributed Load Testing with JMeter (4)

Of course, you would not be pumping load from just one JMeter server, you can set up more ssh tunnelling as -

ssh -L 24002: \

-R 25000: \

-L 26002: -N -f <username>@<server>

and so on…

-N and -f options are used since you only need to set up SSH port forwarding and will not execute remote commands. Hence you will not get shell to execute commands.

Port forwarding syntax - 24001: may seem a little confusing. Herein means localhost (i.e. from the server perspective and not your machine. It means forward my localport 24001 to port 24001 on server. Hence it is -

ssh -L LocalPort:RemoteIP:RemotePort User@RemoteIP

For 26001: - First you need to specify the port on which the remote server will listen, which in this case is 26001, and next follows localhost for your local machine, and the local port, which in this case is 26001.

Configure Client -

Now configure jmeter.properties file in JMeter client as -

remote_hosts= (can also be specified from command line using -R option as specified earlier)
client.rmi.localport=25000 (the port on which results are collected and connection established by one of the RMI)

Notice that we define mode of data transfer on client (master) machine and not on slave machine. This is according to jmeter properties file -

# How is Sample sender implementations configured:

# - true (default) means client configuration will be used

# - false means server configuration will be used


If you want slave machine to decide (probably you would never want that) on mode of sampling then set `sample_sender_client_configured` to false and set mode on each slave machine.

Using any mode which writes results back to master would eventually affect the max throughput of test. According to JMeter -

(Video) Distributed Load Testing on AWS using JMeter


Listeners in the test plan send their results back to the client JMeter which writes the results to the specified files By default, samples are sent back synchronously as they are generated. This can affect the maximum throughput of the server test; the sample result has to be sent back before the thread can continue.


Hence I use mode DiskStore or StrippedDiskStore to have test results sent back to client after test run. Given that you would not have test results being sent to client machine till end of test run, you would like to print result summary on client to know summary of results during test run. Since jmeter version 2.13 I did not have to do anything extra to get summary of test result printed on console :-)

In DiskStore/StrippedDiskStore mode result is saved in java.io.tmpdir. Notice that slave jmeter instance should have permission to write to this file (/tmp or /var/tmp in unix system) else following message would be logged in jmeter-server.log file -

jmeter.samplers.DiskStoreSampleSender: Using DiskStoreSampleSender for this test run

ERROR - jmeter.samplers.DiskStoreSampleSender: Failed to create output file java.io.IOException: Permission denied

To overcome this you can specify your own directory which should be used to used to save test result when starting the jmeter server on slave -

./jmeter-server -Djava.rmi.server.hostname= -Dsun.net.inetaddr.ttl=0 -Djava.io.tmpdir=/home/<user>/testresult

Notice that you would have to create directory if it does not exist. In the following section of this post there are some shell script which could do this for you.

Once the test execution is over then test results would be sent back to jmeter client and stored in the file which was specified using -l parameter when starting the test.Be patient, it takes time for test results to be sent back to client machine ;-) You can verify n/w activity on client machine usingiftop -ncommand once test execution is over. You would usually see higher n/w activity which is an indication of test results being sent to Client machine.

Once all test results have been transferred then you should see following message in client console -

summary + 117 in 5s = 23.4/s Avg: 13 Min: 8 Max: 30 Err: 0 (0.00%) Active: 0 Started: 704 Finished: 720

summary = 181813 in 1027s = 177.0/s Avg: 590 Min: 7 Max: 4464 Err: 0 (0.00%)

Tidying up remote @ Tue Feb 16 15:03:05 CET 2016 (1455631385107)

... end of run

Once test results is transported to client then you can plot graph using jmeter listeners.

If you have highly responsive server then you may end up with following error on jmeter-server.log -

jmeter.threads.JMeterThread: Test failed! java.lang.OutOfMemoryError: GC overhead limit exceeded

Then it is time to reduce thread count or user more powerful test agent till this error disappears.Notice thatthis error is different than usual Out of memory error in jmeter which can be fixed by setting JVM memory arguments in jmeter.sh file. To know more about GC overhead limit exceeded error followSO thread

We had described other properties earlier, except mode. It specifies how results are sent back from server to client. Statistical mode results in reduction of data transfer between server and client hence helps in not overloading JMeter client machine.

Configure Server -

Now configure jmeter.properties file in JMeter server as -

server_port=24001 (port used by JMeter connection. This connection is started by only JMeter client, see SSH tunnelling client above)
server.rmi.localport=26001 (a second port on which connection is established using RMI)

(Video) 0043 - 📈 Guide to Load testing with JMeter - Distributed load generators tutorial

Notice that port numbers 24001 and 26001 are the ones on which port forwarding is established from local JMeter client to remote JMeter servers.

I did not find property server.rmi.localhostname in JMeter version 2.13, hence added it myself in jmeter.properties file.

Start the remote Server -

When starting JMeter server you need to tell JMeter to user localhost ( as its RMI server -

bin/jmeter-server -Djava.rmi.server.hostname=

This starts JMeter server and accepts connections from JMeter client.

Now you can start test from jmeter client and specify localhost as RMI server -

jmeter -n -t script.jmx -R, -Djava.rmi.server.hostname=

And then you would see following message on JMeter client -

Created the tree successfully using <Your_Test_Plan>.jmx

that’s all :-)


  • I got following error when establishing ssh tunnel using command -

<ssh -L 24001: -R 25000:

-L 26001: -N -f tbhadauria@>

<<Warning: remote port forwarding failed for listen port 25000>>

I updated client.rmi.localport to 24000 in jmeter.properties file of Client JMeter and changed the port 25000 to 24000 in the above command above and error disappeared. Refer SO post for more on this error.

  • SSH tunnelling to multiple servers -

The process of establishing ssh tunnelling and launching individual server may become tedious when you have high number of load test agents. To overcome this, I created following crappy shell script which establishes ssh tunnelling and launches Jmeter server on remote servers -




#server_port is the server ip address followed by port end index used in subsequent script

for server_port in; do

server=$(echo $server_port|cut -f1 -d-)

port_end_index=$(echo $server_port|cut -f2 -d-)


(Video) JMeter Intermediate Tutorial 8 - How to build a Distributed Load Test (Throughput Controller)



# start jmeter server on remote instance

ssh tbhadauria@$server 'bash -s' < startserver.sh

# set up ssh tunnelling to JMeter servers

ssh -L $local_to_remote_port1:$local_to_remote_port1 -R 24000: -L$local_to_remote_port2:$local_to_remote_port2 -N -f tbhadauria@$server



And shell script startserver.sh looks as -


# quit existing screens

for session in $(screen -ls | grep -o '[0-9]\{4\}')


screen -S "${session}" -X quit;


#create directory for testresult

rm -r testresult/

mkdir testresult/

chmod 777 testresult/

# start jmeter server

screen -d -m -S loadtest; screen -S loadtest -X stuff "cd apache-jmeter-2.13/bin/;./jmeter-server -Djava.rmi.server.hostname= -Dsun.net.inetaddr.ttl=0 -Djava.io.tmpdir=/home/tbhadauria/testresult;"`echo -ne '\015'`;


  • Specify parameters from command line -

We have learned that we can specify parameters from command line using ‘-J’ literal. But during distributed testing we should use literal ‘-G’

hence if you use customer property i.e. -


then it changes to -


Notice that default JMeter property would remain as it is -

-Jjmeter.save.saveservice.output_format=csv \

The overall JMeter property configuration looks as -

-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.

-G[propertyfile] - defines a file containing JMeter properties to be sent to all remote servers.

-L[category]=[priority] - overrides a logging setting, setting a particular category to the given priority level.

The -L flag can also be used without the category name to set the root logging level.
