    Subject: Re: [apache/cloudstack] Management Server UI (VM statistics page) CPU Utilized
value is incorrect. (#1918)
    
    
    Hi @jayakarteek<https://github.com/jayakarteek> @rafaelweingartner<https://github.com/rafaelweingartner>,
    
    I confirm issue, I tested using an instance with 1 CPU 500Mhz. I'll add screenshots for
cases when CPU utilization is low and high:
    
    First, with little utilization, vSphere shows 51Mhz CPU Utilization, while on Management
Server statistics shows 51% CPU utilization
    [cpu51]<https://cloud.githubusercontent.com/assets/5295080/22908776/1e437a10-f22f-11e6-87a5-6933c990f911.JPG>
    [cpu512]<https://cloud.githubusercontent.com/assets/5295080/22908783/26db1ba6-f22f-11e6-9a83-8743d7abb0e8.JPG>
    
    Then, ran a loop to increase CPU utilization increasing it to ~1609Mhz and Management
Server statistics shows 1609% CPU Utilization,
    [cpu1600]<https://cloud.githubusercontent.com/assets/5295080/22908949/fed18ad6-f22f-11e6-9635-23cd5da38cba.JPG>
    [cpu16002]<https://cloud.githubusercontent.com/assets/5295080/22908951/01fb02fa-f230-11e6-8f72-739709c87984.JPG>
    
    Hope this helps!
