Incremental variable in each iteration/loop in Jmeter Tests

Question

I have below setup for my test plan:

In POST http request, I am sending a variable myCount set to value 0.

As per above configuration, this test will run 100 times but everytime the value of myCount is sending 0.

I want it in incremental for example: for loop 1 value set to 1, for loop 2 value should set 2.

Please let me know how can I achieve this.

Also, I would like to know in Taurus as well.

You can use Counter jmeter.apache.org/usermanual/component_reference.html#Counter — Ori Marko

Thread Group has a pre-defined variable which returns the current iteration number, it's ${__jm__Thread Group__idx}

if you want the counting to start from 1 - go for __intSum() function
There is __counter() function which generates an incremented number each time it's being called
There is Counter configuration element which does the same but you have additional possibility to control the number format, i.e. if you need 0001 instead of just 1 or you plan to re-use the generated variable value later on within the bounds of same request or iteration. More information: How to Use a Counter in a JMeter Test
With regards to Taurus - in case of JMeter executor it supports all the approaches mentioned above

Thank you @Dmitri T. Would be great if we get similar in Taurus yaml.
