Subject [jira] [Created] (AMBARI-7374) Slider View: FE - status of alerts shows as UNKNOWN
Date Wed, 17 Sep 2014 22:01:33 GMT
Srimanth Gunturi created AMBARI-7374:
----------------------------------------

             Summary: Slider View: FE - status of alerts shows as UNKNOWN
                 Key: AMBARI-7374
                 URL: https://issues.apache.org/jira/browse/AMBARI-7374
             Project: Ambari
          Issue Type: Bug
          Components: contrib
    Affects Versions: 1.7.0
            Reporter: Srimanth Gunturi
            Assignee: Srimanth Gunturi
             Fix For: 1.7.0


_There will be no Nagios configuration support for Slider Apps_

The View will rely on Slider client to obtain the number of active instance for each component
type and indicate the health of the component type based on required number of instances vs.
available.

Alerts will be provided in the /apps endpoint : [http://slider-1:8080/api/v1/views/SLIDER/versions/1.0.0/instances/SLIDER_1/apps/?fields=*]

For each app there will be an _alerts_ key containing alert details.
