title: Change the thread count of test plan in JMeter, at run time
body: <p>I want to change the number of threads for a JMeter test plan at runtime. </p>
  
  <p>I have Googled my problem and found a proposed solution to use JMeter plugins. But in this solution I would have to schedule the thread group before running the test plan, which I don't want. I also found <a href="http://www.havecomputerwillcode.com/blog/?p=518" rel="noreferrer">another potential solution</a>  which changes the property, but doesn't affect test plan behavior at run time. </p>
  
  <p>Ultimately, what I am trying to do is change the thread number given in a thread group and have it immediately increase or decrease the number of threads in the current running test plan.</p>
  
  <p>Is this possible?</p>
