JMeter implementation specifies concurrent loop testing

My requirement is to test under a certain number of concurrency , By running continuously for a certain period of time , To verify the stability of the continuous operation of the server , I found a lot of information , It's not hard to find out , Here are my steps

First Set in the thread group , What I set here is continuous operation 2 minute 120 second

Select a good timer
![ Set timer parameters , I set up here 60, That is, the concurrency per second is 1, If you want to measure every second 2 Set as 120, You can also set the number of threads in the thread group , If the thread is 2, Set up here 60, It is also two concurrent inserts of picture descriptions per second
