How to View JMeter Test Results in Real-Time
An interactive Non-GUI mode (CLI) is the most effective strategy to adopt the JMeter. Users preserve commodities and make sure the derived results are appropriate and measurable with the advent of CLI mode. The JMeter GUI can only be used for developing, recording, and debugging tests. This blog mainly discusses three aspects of problems, solutions, and how you can run tests using JMeter Taurus.
The Issue – JMeter Restricts Real-Time Viewing of Test Results
Operating JMeter in CLI mode, on the other hand, can restrict customers to look after the things happening in real-time because CLI mode hides the use of Listeners while the test is running. If you had any Listeners in the test analysis plan, they were presumably specific to GUI-mode and wouldn’t post any data in the non-GUI mode.
If customers prefer to know what is really going through the test lifecycle and its not manage to stay for the test to complete. After that, you need to open the JMeter GUI and attach the selected listener to the test plan using the “sample.jtl” file that their load test created. By incorporating the “sample.jtl” one can easily view the reports and graphs with the help of a Listener.
The Approach – Using BlazeMeter and Taurus to Display Reports in Real-Time
You’ll find a solution with BlazeMeter. With the help of the command line, customers can easily run the already uploaded JMX scripts in the CLI mode (Alternatively with the help of YAML format, you can build new JMeter scripts very easily) with Taurus, an open-source test automation tool, and display the reports in real-time to ensure everything is running smoothly.
Everyone can use BlazeMeter and Taurus for this reason, and there is no need to sign up.
JMeter on Taurus: How to Execute Tests
Why Do JMeter Scripts Need Taurus?
JMeter is a prominent open-source platform for mobile app and website testing. It’s very effective, but it’s not very user-friendly, and its capabilities to report are extremely finite. Taurus is an open-source and free Continuous Testing platform that makes running success tests easier by covering the complexities. Consider a wrapper that can be automated and conveniently envelops JMeter, including all complexity and imperfections.
By using Taurus to run JMeter, you can do the following:
- Execute a JMeter script that already exists.
- Use the YAML text file to quickly build a new script for JMeter.
- Jenkins will help you automate the script.
Installation of Taurus
To begin, get Taurus installed on your system by following these instructions. If the setup path does not have JMeter installed, Taurus will try to install the most recent update of JMeter as well as related plugins.(by default, this is: /.bzt/jmeter-taurus/bin/jmeter). This configuration can be updated to the JMeter location of your choice. (think about adding it in the /.bzt-rc file).
Using JMeter to Run a Script
Taurus has executors for a variety of open-source research software, including JMeter, Grinder, Selenium, Gatling, and others. Since JMeter is the default executor, it’s quite simple to run a JMX file built with JMeter with Taurus! Simply run the bzt order, then specify the JMX route. For instance.
The JMeter test file name, in this instance, is “example.jmx”.
JMeter will be started and the JMX file will be run using this instruction. You’ll observe a dashboard with a full-screen mode of all of the reports from the Taurus within a few seconds. When your experiments are still running, Graphs made with ASCII-art can be found on this dashboard showing main KPIs and statistics for your test.
Steps to implement:
- Install Taurus
- Using the bzt command followed by the JMX path to run your JMX file.“bzt example.jmx,” for example. After a few moments, the Taurus dashboard and files with KPIs and statistics will appear.

Using YAML to Build a Script of JMeter
If you aren’t acquainted with JMeter, a YAML file can be used to build a scenario to be tested using Taurus’ basic configuration syntax. You could do it without even learning about JMeter or launching it!
Get the following illustration.
Including Properties of JMeter
Would you like to use any JMeter properties in your script for JMeter? It’s no problem!
JMeter properties can be defined in two places.
Level of the module: Global
This is how the properties of global are configured.
Level of Scenario: Local
The following properties are configured at the scenario level:
In the device properties section, you can also define JMeter system properties. Artifacts include them in the “system. properties” file.
Using the Reports in BlazeMeter
Another significant benefit of using Taurus to run a script of JMeter is that you have access to the reporting service of BlazeMeter. Although many research tools concentrate on execution rather than reporting, this helps you to easily and interactively access test data, monitor patterns over time, compare multiple executions, and communicate with colleagues. You can also use the reporting service of BlazeMeter even though you’re just using the free edition.
The switch at the command line “-report” is the simplest way to do this. You won’t need to do anything else because the reports will be sent to the reporting service of BlazeMeter. In the text of a console, you’ll find a path to your report, which will open automatically in your web browser that is set as default.
To learn how to generate a JMeter script with YAML and apply JMeter properties to your script, see the extensive description.
You will monitor and review your test results on BlazeMeter while running your JMeter script on Taurus. BlazeMeter reports are simple to use, and they allow you to compare multiple executions, monitor patterns over time, and collaborate. Your samples will be submitted to BlazeMeter if you type “-report”.
Using Cloud Provisioning to Scale
Executing Scripts of JMeter on your system which is local has a number of drawbacks, one of which is that it is not portable – you are constrained to the capabilities of your system which is local. Taurus supports server provisioning, which means you can use your BlazeMeter account to execute your scripts of JMX in the cloud. To run cloud tests, you do not need to be a paying consumer, free accounts will do so as well. To take advantage of cloud provisioning, make the following changes:
Taurus needs a key set of APIs to enter the BlazeMeter cloud, which can be located in the cloud module’s settings. As an example:
You can select from any of BlazeMeter’s cloud locations (to observe available locations list, type bzt -locations -o modules.cloud.token=<API Key>).
Taurus can spread throughput and/or concurrency through multiple locations in the cloud if you assign several locations in the cloud for the same run. You must define a position and its relative weight so as to use cloud locations; the relative weight specifies the number of throughput and concurrent users that will operate in this area.
Automating the Script using Jenkins
The “new normal” is rapidly being Continuous Delivery, particularly for SaaS organizations who are continually introducing new characteristics and enhancing their sites. Although the development of the software industry has made significant strides when it comes to automating processes, research has lagged behind. Taurus comes into play here.
To execute your Taurus test and consider it as a segment of your continuous delivery cycle, use the “Execute shell” section in the project setup in Jenkins.
You can now run your JMeter scripts in CLI mode without having to use the JMeter GUI, and still have all of the analytics you need in a visually appealing format. Get this Jmeter training to learn more from the industry experts.
