JMeter Custom Thread Groups

With any JMeter test, thread groups constitute the basic container for test plan requests and other elements. The simplicity of the basic thread group is such that with enough ingenuity anything is possible. Through clever use of scripting, timing, and logic elements it is possible to simulate any user behavior. However, for simulating complex traffic patterns there is an easier way. One of the most useful plugins for JMeter comes as the “Custom Thread Groups” collection.Read More →

A common question that RedLine13 users ask is how many vCPUs needed for load testing. One example of such a question might be: I want to do a load test with 500k users. I’m trying to decide how many vCPUs I would need for this, and therefore which plan to go for with Redline13. Please could you advise me on how many users you’d recommend per vCPU. AWS has an article in their documentation which speaksRead More →

Uses Cases JMeter Dashboard

In a previous post we described how to enable and access the JMeter Dashboard Report. It is a useful reporting platform for JMeter tests, providing a sophisticated level of detail alongside powerful summary metrics. In this post we will describe some specific use cases for the JMeter Dashboard Report related to running load tests on RedLine13. Determining Success or Failure of a Test One of the primary goals of load testing is to experimentally derive orRead More →

Understanding the Merge Results Feature

 One of the main benefits to RedLine13 is the ability to efficiently scale your load test across multiple load generators.  Ordinarily a challenge would present itself in collecting these results into one unified data set.  With RedLine13 we have something called “Merge Results“.  You can use the Merge Results feature and analyze all your results at once.  In this brief post, we will discuss why many will find this to be useful. What are Merged Results?Read More →

Debug your JMeter Test

As you build your load test, you will need a way to debug your JMeter test. This is often accomplished initially using the JMeter’s GUI. When you move to the cloud however, there may be some differences that cannot be fully evaluated locally. To gain access to similar output – including logs – RedLine13 offers a feature to save output files for your JMeter and other load tests. In fact, there are a few useful things thisRead More →

Compare Load Tests Results using CSV Data

RedLine13 provides detailed real-time and post-test metrics, but there may be certain cases where you want to compare load test results.  In this post, we will discuss some of the ways you can compare metrics both within the same test, and between multiple tests. Compare Results from Multiple Load Tests It is possible to compare results between multiple test runs by combining exports and using a spreadsheet application like Excel.  Below we have a graph whichRead 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 →

JMeter Test Capacity Limits

Depending on your testing goals, whether using JMeter or something else, pushing your target application to a point of ultimate failure may be one of your objectives. In this post we will discuss what signs you might see in your load test when your target test application becomes “overwhelmed”. We will also explore some cases where problems in the test or the network can mimic an overwhelmed state. The extreme scalability of a cloud-based architecture enablesRead More →
