[jira] [Created] (AMBARI-15936) Cluster CPU widget is wrong

Cyril Scetbon created AMBARI-15936:
--------------------------------------

             Summary: Cluster CPU widget is wrong
                 Key: AMBARI-15936
                 URL: https://issues.apache.org/jira/browse/AMBARI-15936
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.2.0
            Reporter: Cyril Scetbon
            Priority: Minor


I'm using HDP 2.4 to run Yarn applications. When I look at my current NodeManagers CPU, the consumption is low. However on Ambari interface, the default "Cluster CPU“ widget displays a high CPU (91%). When I check the expression used, it uses cpu_idle._sum (see http://picpaste.com/Screen_Shot_2016-04-16_at_22.13.43-gS4XsIGb.png) which is a metric that I can't find if I try to create a new widget http://picpaste.com/Screen_Shot_2016-04-16_at_22.09.56-DJK3v4Wd.png 
Can it be the reason why the CPU consumption displayed is totally wrong ?
