title: How to check the acessibility of a page using JMeter
body: <p>Have to check the accessibility of one API. If it has not opened within any stipulated time and then send email to stakeholders. When I am using "Duration Assertion" to check the time duration, than JMeter will access the page first calculate the time than compare with the given time and do the action.</p>
  
  <p>But the problem is to check the accessibility. So when it is not accessible or down than the meter is waiting for it irrespective of the time limit.</p>
  
  <p>So how to kill the process and send the email if the API is not accessible or down. </p>
