title: OpenTSDB - Get all metrics via http
body: <p>I am getting some data from OpenTSDB, but cannot work out how to get a list of metrics via http? </p>
  
  <p>For reference, here's the c# code I'm using to get databack. Is there a url that would return all metrics?</p>
  
  <pre><code>var request = WebRequest.Create("http://localhost:4242/api/version?jsonp=callback");
  request.ContentType = "application/json; charset=utf-8";
  string text;
  var response = (HttpWebResponse)request.GetResponse();
  using (var sr = new StreamReader(response.GetResponseStream()))
  {
      text = sr.ReadToEnd();
  }
  
  uxResponse.Text = text;
  </code></pre>
  
  <p>The default OpenTSDB website provides this functionality as per following screenshot, I want to mimic this from a my asp site.</p>
