Step by step load test with JMeter-part 5

CSV data set config

Now we will bulk register customers by reading from a CSV file

Create a file in bin folder named “customers.csv”

Prepare customers.csv file like that:

Now, Right click on Simple Controller and click on Add > Config Element > CSV Data Set Config

Set following configuration:

variable names are the customer properties

Now disable the jr223 PreProcessor as we will not use it right now

Then disable also the following HTTP Requests as these are currently not needed

Now, select Thread Group and set Thread as 5 because we will bulk create 5 customers from our CSV

Now clear previous history and run the project

You will see first 5 customers has been created

Perform Load Test from CLI (Command Line Interface)

Now disable CSV data set config and enable all our previous simple controllers and HTTP Requests

Go to your bin folder and open with command prompt

Then hit following command:

jmeter -n -t load-test-demo.jmx -l load-test-demo.csv

-n specifies non gui mode
-t specifies configuration file
-l specifies log file that will generate by jmeter
log file extension can be csv, xml or jtl

Hit enter and the load will be execute. You will see the summary result in console window


If jmeter is not recognized by the command prompt, then set jmeter home from Environment Variables

and add path

Now if you hit the command jmeter, it will no more show the error and will open the JMeter

Generate Report

Now we will generate a html report so that our load test result is more clear

Delete the “load-test-demo.csv” generated in bin folder

Hit following command in cmd

jmeter -n -t load-test-demo.jmx -l load-test-demo.csv -e -o Reports

A folder named “Reports” will be generate in bin folder

Open the index file and and you will see a result has been generated

When you need to generate the html report again, delete the log file “load_test_demo.csv” and Reports folder and hit the command again

Distributed Load Test

Distributed load test is a process where master computer and multiple slave computers are connected each other and the master computer command the slaves to execute load together

First you have to LAN connect 3 computers and disable firewall

Make sure that every computer can ping each other
pc-1 IP:
pc-2 IP:
pc-3 IP:

Now we will configure our JMeter

Go to JMeter bin folder and find out file
open the file and find “remote_hosts”

Remove the “#” and edit this line:

Now start the jmeter-server.bat in the slave pc’s
suppose, pc-2 and pc-3 are our slave pc

Then from the master pc, go to bin folder and open CMD
Then hit following command:

jmeter -n -t script.jmx -r //run all server
jmeter -n -t script.jmx -R, //run specific server

Here’s the full project:
