Here is an example from my top:
Cpu(s): 6.0%us, 3.0%sy, 0.0%ni, 78.7%id, 0.0%wa, 0.0%hi, 0.3%si, 12.0%st
I am trying to figure out the significance of the %st field. I read that it means steal cpu and it represents time spent by the hypervisor, but I want to know what that actually means to me.
Does it mean I may be on a busy physical server and someone else is using too much CPU on the server and they are taking from my VM?
If I am using EBS could it be related to handling EBS I/O at the hypervisor level?
Is it related to things running on my VM or is it completely unaffected by me?
