CPU information collected by the Red Hat virtualization function (Xen)
If a physical CPU is shared by multiple domains under the Red Hat virtualization function (Xen), which can be used in Red Hat Enterprise Linux v5.0, some of the CPU information collected by each domain may contain larger values than the real values.
The following items are affected:
CPU time and utilization rate (SUM_PROC,UX_CPUBUSY)
Process CPU time (UX_PROCESS)
Point
If a domain has exclusive use of a physical CPU, the correct information will be collected.
Refer to Chapter 4, "Data Formats" in the Reference Guide for details on the relevant information.
