---------------------------------

             Summary: Alert display randomly shows "No alerts" and then populate with alerts, back and forth
                 Key: AMBARI-5201
                 URL: https://issues.apache.org/jira/browse/AMBARI-5201
             Project: Ambari
          Issue Type: Bug
          Components: controller
    Affects Versions: 1.5.0
            Reporter: Nate Cole
            Assignee: Nate Cole
             Fix For: 1.5.0


Service alerts show "No alerts" then actual alerts, then "No alerts", back and forth.  This was observed on a 800-node cluster.

The issue is that on large clusters, the call to retrieve Nagios alerts takes a long time, and eventually times out.  The fix is to make the call asynchronous so as not to block the UI.  The reason for Nagios timeout is another issue.
