Subject [GitHub] cloudstack issue #1918: Management Server UI (VM statistics page) CPU Utiliz...

Github user rafaelweingartner commented on the issue:

    https://github.com/apache/cloudstack/pull/1918
  
    @nvazquez, this helped.
    
    I checked the “VmwareResource.java” at line 5113 is obtained the CPU usage of VM.
From @jayakarteek explanations I understood that the usage does not come as %; VMware systems
show the value as a continuous value of CPU used in MHz.  Does not the object “objProps”
(created at line 5092) contain the configured CPU for the VM? So, the proper conversion could
be applied on “VmwareResource.java” at line 5186, making the POJO (VmStatsEntry) consistent;
otherwise, there is a variable called “cpuUtilization” that gives the idea of percentage/ratio
of usage, but in reality, it is carrying the real used valued of CPU in MHz.
    
    I also understood the issue regarding the CPU cap, but do not you think that if users
select a service offering of 500MHz and their VMs are consuming 1GHz, it would be interesting
to show that the VM is using more than they would expect? The cloud provider is being very
generous in this case :)
