Hi All, I have a followup question on what Dan replayed. When talking about CPU percentage is it out of the VM's virtual CPU(s) or is it out of whole VDS CPU(s)?
In case of "out of vm's virtual CPU(s)", what will be the best way to get my goal(calculating the VM cpu usage percent out of the total VDS cpus)? I could count all virtual CPUS in the VDS host and calculate: (cpuUser+cpuSys)/(#cpusInVds*100) Suggestions will be much appreciated :) Dan - 10x for your help ----- Original Message ----- > From: "Dan Kenigsberg" <dan...@redhat.com> > To: "Kobi Ianko" <kia...@redhat.com> > Cc: "Doron Fediuck" <dfedi...@redhat.com> > Sent: Monday, December 30, 2013 1:52:44 PM > Subject: Re: Calculating the VM cpu usage percent out of the total VDS cpus > On Sun, Dec 29, 2013 at 11:29:04AM -0500, Kobi Ianko wrote: > > Hi Dan, > > On my current task I need to understand how to extract a number that > > represents: > > The VM cpu usage percent out of the total VDS cpus. > vdsClient -s 0 getAllVmStats > provides cpuUser and cpuSys per VM.
