How to use throughput controller for much samplers in jmeter?

if the number of samplers is very high, nearly 100, how to use throughput controller in jmeter? i want all samplers to be sent with equal number by jmeter.

my test configuration: ultimate thread group : 50 threads, 10 minutes, ramp up 10s, ramp down 10s

sampler1 ,

sampler2 ,

...

sampler100.

throughput controller is not used.

when the test is executed the total request numbers will be like this:

sampler1 : 150 ,

sampler2 : 145 ,

sampler50 : 5 ,

sampler100 : 0

this is not the case that i want. if i use the throughput controller (all the samplers are in the throughput controller), the result will not change satisfactory. have any idea for the solution?

Throughput Controller doesn't guarantee that its children will be executed specified amount of times (or at least once), it can only limit the number of its children execution to the defined value.

If you have 100 samplers and 10 minutes + 20 seconds test duration if average response time exceeds 6 seconds - not all samplers will be executed

If you want all the 100 samplers to be executed at least once within the bounds of 10 minutes time frame you need to limit the time JMeter waits for the response to something below 6 seconds, i.e. to 5 seconds.

In case of HTTP Request sampler the timeout setting can be found at "Advanced" tab

enter image description here

or better use HTTP Request Defaults, in this case you won't have to set the timeout 100 times.

Also make sure that "Action to be taken after a Sampler error" is set to Continue

enter image description here

as having 150 occurrences of execution of 1st sampler most probably means that there is an error somewhere and the user is restarted so it executes samplers from the beginning once again
