Subject [jira] [Created] (AMBARI-8118) HostComponent requests including Nagios are not performant
Date Mon, 03 Nov 2014 17:21:33 GMT
Nate Cole created AMBARI-8118:
---------------------------------

             Summary: HostComponent requests including Nagios are not performant
                 Key: AMBARI-8118
                 URL: https://issues.apache.org/jira/browse/AMBARI-8118
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 1.7.0
            Reporter: Nate Cole
            Assignee: Nate Cole
             Fix For: 1.7.0


Requests like the following take a long time to process on large clusters.

This call includes asking Nagios for alert data, when that data is never used.  This information
now comes from the NagiosPropertyProvider class, not the HttpProxyPropertyProvider class.
