> Cluster CPU widget is wrong

> Key: AMBARI-15936

> 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 ?
