The approach which is normally used in JMeter is placing your request under the While Controller which will be checking the Status value which in its turn can be fetched from the response using a suitable Post-Processor so the request will be retried unless the "Status" changes to some value which you expect (or times out). Author (s): Afsana Atar. . save. But when I look at the results it only takes the FIRST var and uses that for ALL of the loops. If you want the "counter" to start. e.

Logical Controllers: It lets you control the order of processing of Samplers in a Thread. If you place the whole. If you additionally want to save each "pageItem" into a separate JMeter Variable suitable for iterating via ForEach Controller you can add another piece of code: response. Jmeter ForEach controller is not getting/taking all the values from regular expression variable results when match count set to -1. Q&A for work. In this example, these thread groups are named “First Thread Group” and “Second Thread Group. It proves that even though the stage IF controller evaluates to false - jmeter still runs the user defined variable under the stage IF controller (wtf) So it seems that even though only one of the if branches runs jmeter still evaluates all user defined variable regardless of where they are placed in the tree.

Add value 50 to Loop Count field as below figure. The Following Example Demonstrates the Throughput Controller: Open the JMeter and then add thread Group into your Test Plan and enter the number of Users as 10. Loop Controller. Total 15 user requests will be sent to Google server by JMeter. I'm using While Controller based on the number of servers to iterate and execute the url requests. 0059° W latitude_2=32. However, once you have such numbers, it becomes increasingly difficult to tweak thread groups and timer delay settings within JMeter to simulate a targeted requests per second (RPS) value for the modules. The main purpose of the If Controller is to control the JMeter execution script flow. I have tried adding foreach controller with a regular expression extractor, but Im not sure I have done it correctly: Im new to JMeter so Im not sure if Im doing any of this. Please note that this is a prototype, our actual use case will have 1000-5000 nodes in the array and will do more then just an HttpRequest.
