Subject [jira] [Created] (AMBARI-3228) NameNode HA: Nagios alert issues when NameNode HA is enabled
Date Fri, 13 Sep 2013 18:03:52 GMT
Dmytro Sen created AMBARI-3228:
----------------------------------

             Summary: NameNode HA: Nagios alert issues when NameNode HA is enabled
                 Key: AMBARI-3228
                 URL: https://issues.apache.org/jira/browse/AMBARI-3228
             Project: Ambari
          Issue Type: Task
          Components: agent
    Affects Versions: 1.4.1
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
             Fix For: 1.4.1


When HA is enabled, Ambari is showing all the Nagios alerts for both NameNodes.
There are several problems.

1. Alerts for HDFS as a service are duplicated (aggregate alerts):
Blocks health
2. Alerts for individual NameNodes cannot be distinguished from each other. For example, there
are two entries for "NameNode host CPU utilization" and "NameNode Web UI" but you can't tell
which one belongs to which.
