I am trying to do performance test of my Rest API via Jmeter and generating report from blaze Meter.

I am testing a POST operation. I want to send 50 request to the server by 50 users, means that each 1 user gonna send 1 request with delay of 1 second. I want to send 1 request by 1 user so it will make 50 request by 50 users. My Jmeter Configrations are: No of Threads: 50 Ramp up peroid : 50 Loop Count: 1

But When I genrate report via Blaze Meter, my Max Virtual Users are 4 instead of 50. Why is it 4? What am I doing wrong? enter image description here

Max Virtual Users means max concurrent users.

Having 50 thread and a ramp up of 50 seconds in a single loop cycle, not all threads are concurrently running; when some threads already finished other have still to start.

You should get a greater Max Virtual Users value running multiple loop cycles.

Just increase loop count, you are running into a situation when some threads have already finished their job and others have not yet been started.

See JMeter Test Results: Why the Actual Users Number is Lower than Expected article for detailed explanation.
