Hi, 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 <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 <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 ? Is it a known bug ?
Thanks
