How to Install Apache JMeter on Ubuntu 20.04

Apache JMeter is a load testing tool. It is open-source and Java-based. JMeter can be used for the analysis of a system’s functional behavior. It measures a system’s performance under a load test. The load, in this case, simulates those end-user behaviors that approach the limitations of an application’s specifications. JMeter can be used for simulating loads that are variable or heavy. The simulation may be conducted on single or multiple servers. It may alternately be conducted over networks or objects testing a system’s strength. JMeter simulates a group of users. They send requests to a server or network. The returning statistics are shared back with a user through visual diagrams. JMeter also offers support for browser plug-ins. In this tutorial, we will show you how to install and use Apache Jmeter on Ubuntu 20.04.

Prerequisites

• A fresh Ubuntu 20.04 Desktop VPS on the Atlantic.net Cloud Platform.

Next, you will need to add some components in your Test plan.

Add Thread Group

To add a thread group, right-click on the plan1 and click on the Add => Threads (Users) => Thread Group. You should see the following page:

Here, you will need to provide the Number of Thread Users, Loop Count and Ramp-Up Period. Once you are done, you can proceed to the next step.

Add HTTP Request Sampler

Next, you will need to add the HTTP Request Sample elements to represents a page request that each thread (user) will access.

To add it, right-click on Thread Group and click on the Add => Sampler => HTTP Request. You should see the following page:

Here, you will need to provide a name or the IP address of your web server that you want to test.

Add View Results in Table Listener

Next, you will need to add the Listener to output the results of a load test.

To add a Listener, right-click on HTTP Request and click on the Add => Listener => View Results in Table. You should see the following page:

Step 6 — Run Test and get the test result

At this point, your basic test plan is setup. Now it’s time to run the test.

Now, click on the green arrow button to start your test plan. You should see the test results in the following page:

Conclusion

In the above guide, you learned how to install the Apache JEmeter on Ubuntu 20.04 desktop. You also learned how to create a basic test plan and run the test. I hope you can now easily use Apache JMeter for load testing.

If you would like to host your application on the cloud server then I would recommend to try Atlantic.net Cloud and get started with one full year of free VPS hosting in the cloud!

How to install Apache JMeter in Ubuntu

After developing a new website, it is very important to perform some tests to find out the limitation of the site, and take necessary actions to remove the limitations for making the site more appropriate for the visitors before publishing. One of the important tests for any website is a load test. How many requests the website can handle at a time or how the website performs when a large number of requests appear on the site can find out by load test.

Apache JMeter is the best tool developed by Stefano Mazzocchi of Apache Software Foundation to perform this type of test and check out the performance of any website. It is used to create a large amount of virtual concurrent traffics to the website for doing the load test. It is open-source software. So anyone can download, install and customize this software to do the test. It is mainly designed for testing web application, but now it is also used for database testing, stress testing, distributed testing, and functional testing. How you can install and run this software is shown in this tutorial.

Install JMeter

JMeter is a developed by Java. So you require to install the latest version of JRE or JDK to run JMeter. If you have installed Java before then run the following command to check the version of the installed Java.

The following output will appear if Java 9 is installed on the system.

If you didn’t install Java before then you can follow the steps from the following tutorial link to install Java before starting the next step.

Simple Test using JMeter

It is discussed earlier that JMeter can be used for various types of testing. How a simple load test can be done using JMeter is shown in this part of the tutorial. Test name is set to Test Plan by default. If you want you can change the default value. Here, Name is set to Test Plan1 and test1 is set as a comment which is optional. Next, you have to set the variables that you want to use in your test. Here, the site is set as the variable name and tutorials4uhelp.com is set as value. This test will do the load test based on the next configuration of the site tutorial4uhelp.com.

Right-click on Test Plan1 from the left navigation. Click on Add, next Thread (Users) and next Thread Group. It is used to set action, properties, and schedule of Thread Group before starting the test.

In Thread Group, Five types of actions can be taken when any sampler error occurs. These are,

• Continue
• Start Next Thread Loop
• Stop Thread
• Stop Test
• Stop Test Now

You can select any of the above actions for your test. Here, the default option is used. Next part of Thread Group is to set Thread Properties. The properties are,

• Number of Threads (users)
  This property is used to assign the number of virtual visitors that you want for the testing. 15 is set here.

• Ramp-Up Period (in seconds)
  This property is used to assign the time between two threads. 5 seconds is set here.

• Loop Count
  This property is used to assign the number of times the thread will run. You can run the thread for unlimited times by selecting Forever checkbox. 1 is set here to run the thread for just one time.

There are other two properties which are “Delay Thread creation until needed” and “Scheduler”. These properties are remained unchecked here. Scheduler Configuration part is used to set the execution time of the test and it will be used in the test if you checked the Scheduler.

Next, you have to set the Sampler type to do the test. Here, HTTP Request is set as Sampler, to hit the server for the resources.

In HTTP Request part, you have to set Web Server, HTTP Request type for the test. You can use HTTP or https as protocol based on your server. By default, HTTP is used. You have to set domain name or IP address of your server in Server Name or IP field. Here, ‘tutorials4uhelp.com’ domain is used as Server Name. Other values remain as the default value.

Next, you have to set Listener type. It is used to view the test results in various format. Here, ‘View Result in Table’ is selected.

Now, you can click on the start button to start the test based on the assigned configurations. You have to wait for some time to complete the thread in this step.

The following screen will appear after completing the test.

Conclusion

JMeter is a popular testing tool now but this software has some limitations. It consumes more memory while doing the test. It is not good for desktop application and it can’t render HTML and JavaScript like the browser. If you are preparing to publish your website then it is very important to check the performance of your site. You can use JMeter for checking the performance of the site by doing different types of test on it. It will help you to detect the problems of your site and take proper actions to solve it.
