The JMeter Random Controller vs Random Order Controller

When it comes to introducing random variability within test plan execution, there are two similarly named plugins for JMeter which are up to the task.  Each of these applies randomization to your tests, but in different ways.  In this brief post, we will analyze the similarities and differences between the JMeter Random Controller and the Random Order Controller. The Random Controller is one of two built-in logical controllers for randomization. When you add an instance ofRead More →

Using ChatGPT to Analyze JMeter Load Test Results

In a previous post we discussed how ChatGPT could be used to assist and partially automate JMeter test plan creation. In this post, we will explore how ChatGPT can be used to help analyze and compare JMeter load test results. I’d like to take a more illustrative approach showing the types of tasks that ChatGPT is good at solving. This will give you a better idea of how to structure queries and get the most outRead More →

Compare JMeter Test Results

A common approach to load testing often involves running a series of load tests to ascertain the performance of a target test application. The question that is sometimes asked is how to compare JMeter test results from two or more runs of a similar JMeter test on the same graph. In this article we will show you how to compare the results of two separate load tests using the Merge Results plugin. In a previous postRead More →

Overlooked JMeter Plugins You May Not Know About

We previously talked about the Top 10 JMeter Plugins and the versatility of JMeter through the use of plugins. We overviewed the top ten most popular plugins for JMeter that test designers are using today. In this follow-on post we’ll overview some overlooked JMeter plugins – some of which you may want to know about. Results and Reporting Synthesis Report – Using this plugin, you can create a separate *.JTL file that contains filtered results from yourRead More →

ChatGPT Assisted JMeter Load Testing

There has been a lot of excitement surrounding large language models (LLMs) and especially ChatGPT made available by OpenAI. Heralded as a paradigm in making powerful AI capabilities widely accessible, the GPT-3.5 and GPT-4 models behind the ChatGPT interface continue to find uses in business, data science, linguistics, and writing that did not exist in the short time before their release. In this article, we will illustrate how the LLM behind ChatGPT can be leveraged toRead More →

Protecting Sensitive Data

One of the primary functions of a load test is to vet target test applications to see how well they can hold up to production conditions. In that endeavor it is sometimes necessary to provide login credentials and other protected information to be used in conjunction with these tests. This can present a challenge in protecting sensitive data when load testing in the cloud. In this post, we will cover how to test with JMeter inRead More →

Being fully managed means that the configuration, startup, data collection, and termination is handled automatically with no coding or scripting required. This means you can scale to any level simply by specifying the quantity of servers you wish to run, to nearly limitless capacity with minimal effort. RedLine13 Cloud Architecture RedLine13 is a platform forRead More →

How to Run a Multi-Region Test

RedLine13 integrates with AWS to handle the spin up, management, and termination of your load generator servers without you ever having to worry about any of those details.  We also support starting load generators from any AWS region.  This is useful for when you want to simulate traffic which originates from geographically diverse sources.  In this brief post, we will show you how to run a multi-region test to achieve this. This is available in ourRead More →

Enabling Public IPs on your RedLine13 Load Generators

One thing you must be aware of is ensuring that your load generators are visible to RedLine13.  This is accomplished through assigning public IP addresses.  In this post we will show you how to configure that and successfully run your first load test. What is a Public versus a Private IP? A public IP address refers to its ability to be accessed from external networks – e.g., the internet.  On the other hand, a private IPRead More →
