Extracting Metadata from Load Generator Instances

RedLine13 load generator instances are backed by AWS EC2 instances. AWS exposes a special locally-addressable endpoint that returns metadata about that instance. Using this, you can ascertain such things as the region in which your instance resides, private and public addresses, and instance tags amongst other useful data points. A specific example of where this would be useful is where you have defined a load test to run in multiple regions, with a number of EC2-backedRead More →

Pitfalls of Selenium Load Testing

This is available in ourRead More →

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 →
