---------------------------------
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.
