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 →

AWS Multiple Account Setup

There are situations where separation between your application environment and load generating environment are necessary.  In fact, it is generally a feature of a realistic, well-architected load test.  In this article we will explain how you can easily and conveniently configure an AWS multiple account setup for load testing as a measure to secure your application environment. Configuring Access between Multiple Accounts RedLine13 integrates with your AWS account to provision resources on your behalf.  With AWS,Read 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 →

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 →

Server Index is now a JMeter Property

JMeter tests running on RedLine13 with multiple load generators have visibility to the server “index” number as a JMeter property.  One of our customers was running large scale load tests across multiple servers.  They needed a way to correlate test plans running on individual server machines, something akin to the example described below.  Sometimes useful features come from our customers solving real-world issues, and this is an example of one such case. This property – rl13_agentindexRead More →
