title: JMeter insert server name or IP dynamically
body: <p>I am trying to create JMeter tests and use the same tests for different environments- QA, Staging, Dev etc. 
  I want to dynamically change the IP address by either changing the CSV File or passing the value through ant script or manually through command prompt. Unfortunately, I haven't been able to do so. The Test doesn't pick up the value from CSV file or from the command prompt. </p>
  
  <p>Can someone please help me.</p>
  
  <p>Thanks in Advance.</p>
