Fwd: Calculating the VM cpu usage percent out of the total VDS cpus
by Kobi Ianko
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
