How can I send an http request at a specific time?

How to send an HTTP request at a specific time in Jmeter

• I want to send an HTTP request every fifteen seconds, e.g.: Send an HTTP request to the first user at T+0 (e.g. 10:00:00 AM) Send the same HTTP request to user 2 at T+15sec (e.g. 10:00:15 AM) Send this request to user 3 at T+30

• Answer:

  If you want to start the test at a specific time, you can use JMeter scheduler. If the Start Time is future time, JMeter will wait & start the test @ that time. If you need to add users for every 15 seconds, use the Ramp Up period. For ex: total no of users are going to be 10, you need 1 user for every 15 seconds, ramp up period should be 150 seconds (15*10).
