How do I use throughput controller in Jmeter with multiple samplers

Question

I have a plan that looks like the following:

• thread group
  • throughput controller for homepage (40%)
    • sampler A
  • throughput controller for page 1 (20%)
    • sampler B
  • throughput controller for signup and page view (40%)
    • sampler C (for signup)
    • sampler D (for https(logged in) page view 1)
    • sampler E (for https(logged in) page view 2)

Let's assume that the logged in page view 1 and 2 have to happen right after signup. Due to multiple samplers in the third throughput controller, it's not really possible to achieve the 40% (for that whole group).

For 10 threads, 1 loop, I expect to see the following counts:

• Sampler A: 4
• Sampler B: 2
• Sampler C + D + E: 4

but that's not happening. Any idea how I can achieve that?

Answer 1

This will happen after a certain time of run. What are you observing ?

Answer 2

Instead of placing all 3 samplers under one Throughput Controller use 3 Throughput Controllers having samplers C, D and E as children.

Throughput Controllers need to be configured as follows:

• Percent Executions
• Throughput: 40.0
• Per user: unchecked

See Running JMeter Samplers with Defined Percentage Probability guide for more information on how to control samplers execution rate.
