title: Custom metrics confusion
body: <p>I added <a href="https://micrometer.io" rel="nofollow noreferrer">https://micrometer.io</a> to our staging server in google cloud.  The metric does not show up in "Cloud Run Revision" resource types.  It is only visible if I select "Global" as seen here...</p>

  <p>The instructions were very simple and very clear (MUCH UNLIKE opencensus which has a way overdesigned api).  In fact, unlike opencensus, it worked out of the box except for it is not recording into "Cloud Run Revision".</p>
  
  <p>I can't even choose the service_name in the filter so once I deploy to production, the metric will be recording BOTH prod and staging which is not what we want.</p>

  <li>How do I debug micrometer further</li>
  <li>If anyone knows offhand as well what the issue might be, that would be great as well? (though I don't mind learning micrometer and debugging it a bit more).</li>
