When I run top
from my VPS, at the %Cpu(s)
row, I see a few values, e.g. %us
, %sys
, %wa
, etc
I'd like to ask whether these are the stats for the VPS only, or for the whole node (dedicated server)?
For example, let's say %sys = 10
, does it mean that the Percentage of the CPU for system processes of the node is 10%, or does it mean Percentage of the CPU for system processes within my VPS is 10% of the allocated CPU of the VPS (Since system processes
may refer to either the dedicated server or only the VPS)
Let's take another example, %us = 20
, does it mean the sum of Percentage of the CPU for user processes of all VPS servers in the node is 20%, or does it mean the sum of Percentage of the CPU for user processes of all users within my VPS is 20% of the allocated CPU of the VPS (since user processes
may refer to either users within my VPS, or the VPS users within the node)?
I'm not clear about this, because VPS is also a system and it has its own users, and the node is also a system and it has its own users (the users of the node are the VPSs, if I'm guess correctly).
Are there any difference in explanation between OpenVZ or KVM VPS?
Thank you very much
