title: How to use Metrics for non-blocking implementation
body: <p>I like to get an idea of how we can use metrics for non-blocking methods. Is it possible? Please give some idea.
  In normally i used metrics as follows</p>
  
  <pre><code>public void methodRequest(){
    final Timer.Context context=responses.time();
    try{
      doWorks.
    } finally{
      context.stop();
    }
  }
  </code></pre>
  
  <p>Can we get metrics in a similar way for the non-blocking methods</p>
