title: How to make jmeter do log replay based on time stamps present in access log lines
body: <p>I recently started load testing my webapp.</p>
  
  <p>I used apache access log sampler. I followed this tutorial. </p>
  
  <p><a href="https://jmeter.apache.org/usermanual/jmeter_accesslog_sampler_step_by_step.pdf" rel="noreferrer">https://jmeter.apache.org/usermanual/jmeter_accesslog_sampler_step_by_step.pdf</a></p>
  
  <p>I am able to make it work. But now the problem i replayed all the get requests in less than 10 mins.</p>
  
  <p>I want jmeter to run the get requests based on the time stamp at which the get request is posted.</p>
  
  <p>I am not able to find any such configuration online.</p>
  
  <p>I can write script to curl the get request at that particular timestamp. But i want to use jmeter.</p>
  
  <p>Is it possible.</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I created a sample csv file with below lines:</p>
  
  <pre><code>0,/myAPP/home
  5000,/myAPP/home
  5000,/myAPP/home
  </code></pre>
  
  <p>First i created a thread group as shown in image:

  <p>Here i selected loop count forever. If not selected only first line in csv file is running.rest of the lines are not running.</p>
  
  <p>Now i added csv data set config as shown in image:

  <p>Now i added constant timer as shown in image:

  <p>Now i added HTTP request as shown in image:
  <img src="https://i.stack.imgur.com/DnlEA.png" alt="enter image description here">
  I added view results tree listener and hit the play button. </p>
  
  <p>When i see the sample start in view result tree for each of the samples, the delay is not according to the delay present in csv file. What am i doing wrong.</p>
  
  <p><strong>EDIT2</strong>
  I made the constant timer as child of the HTTP request. Please find the timings of the requests in the below screen shot. Do you see anything wrong .</p>

  <p><strong>EDIT3</strong></p>
  
  <p>I followed bean shell timre approach and it worked fine when the delay is greater than previous response time. But it didnt work properly when previous response time is greater than delay. </p>
  
  <p>I modified the csv file as below ( reduced delay to 100 msec)</p>
  
  <pre><code>0,/myAPP/home
  100,/myAPP/home
  100,/myAPP/home
  </code></pre>
  
  <p>I deleted constant timer and added below bean shell timer.</p>
