Date Tue, 15 Oct 2013 08:25:42 GMT
Valery Ciareszka created CLOUDSTACK-4868:

             Summary: incorrect cpu usage values in dashboard
                 Key: CLOUDSTACK-4868
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: 4.2.0
         Environment: KVM (CentOS 6.4) + CloudStack 4.2.0
            Reporter: Valery Ciareszka

If cpu.overprovisioning.factor for cluster is being changed, dashboard reports incorrect values,
unless all vms are restarted (stop/start).

I.e. I configured cluster and set cpu.overprovisioning.factor to 6 and started a number of
Current usage is reported correctly.

change cpu.overprovisioning.factor to 12 at cluster settings
Wait for 5-10 minutes and you will see that cpu usage was doubled.

If you will stop/start all vms (including system vms/virtual routers), then you will see true
CPU usage in dashboard.
