First of all you won't be able to create such a load from a single machine, go for Distributed Testing when one JMeter server orchestrates multiple slave machines (load generators) executing the same script at the same time. They help customise the logic that JMeter uses to determine when to send requests to the server. In regards to placement, you need to provide enough iterations to CSV Data Set Config so it could go for 2nd and further lines. Steps to Follow While Performing Distributed Load Testing. 1. The scenario will be the following: async request 1 and async request 2 will run in parallel to samplers that are in the “[Simple Controller] Main Flow” controller. JMeter. The order of the incoming request can be changed by the Logic Controllers from their child elements. JMeter implements this while loop by using the JMeter.

I have setup step 2 to use Loop Controller, but I find the only way to get the run time of the test to 15 minutes is to play with the Loop Controller's. Add a JSR223 Sampler just before the While Controller and store the current time into a JMeter Variable using the following code: SampleResult. Click on “Thread group-> Add->Config Element -> CSV Data Set Config”. Transaction Controller's cost is relatively low, it's just generating a virtual SampleResult plus adding metrics from each and every child to this virtual sampleresult plus sending the signal to the Listeners (if any) There is no sense of having a Transaction Controller with only one child Sampler because it's. 162k 5 5 gold badges 85 85 silver badges 134 134 bronze badges.
