Adding users one after another in JMeter

Question

I need to perform the following scenario in JMeter:

Every 20 seconds a user will start pinging the server (will ping every 5 seconds) 1000 users.

So it start with one user that will ping every 5 seconds and after 20 sec another user will start pinging every 5 sec, and this will continue for 1000 users.

At the end 1000 users will ping together every 5 sec and all this need to run for 24 hours.

Answer 1

Define Thread Group with 1000 users,

Ramp Up Period 20000 - meaning every 20 seconds new users will start

Loop Count = 17280 (5 seconds per day count)

and add as a child to your ping request a Constant Timer with 5000 milliseconds

It will execute every 20 seconds a new user which will ping every 5 seconds. example in View Results Tree:
