--------------------------------------
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

Can it be the reason why the CPU consumption displayed is totally wrong ?
