title: ELB metrics not found in CloudWatch
body: <p>I have a load balancer in ap-northeast-1 (Tokyo) region.</p>
  <p>According to this <a href="http://blog.celingest.com/en/2013/11/07/understanding-new-elb-metrics-in-cloudwatch/" rel="nofollow noreferrer">article</a>, I think I should be able to find <em>Backend Connection Errors</em>, <em>Surge Queue Length</em>, and <em>Spillovers</em> metrics in CloudWatch. But I can't find them.</p>
  <p>Are these metrics only available in specific regions?</p>
  <p>I've googled for hours but failed to find an answer.</p>
  <p>Currently I can see 15 metric for my ELB, which are</p>
