You work as a Network Administrator at AIOTestking.com. AIOTestking.com has an Active Directory
Domain Services (AD DS) domain named AIOTestking.com. All servers in the AIOTestking.com domain
have Microsoft Windows Server 2012 R2 installed.
The network includes virtual machines (VMs) running on Windows Server 2012 R2 Hyper-V host
servers. One of the Hyper-V host servers is named TESTKING-SR31.
You suspect that the processor load on TESTKING-SR31 is high and is therefore impacting the
performance of the virtual machines (VMs) hosted on the server.
You need to monitor the processor usage on TESTKING-SR31. You need to measure the total
physical processor utilization of the host operating system and all guest VM operating systems.
Which of the following performance monitor counters should you monitor?
A.
\Processor(*)\% Processor Time
B.
Hyper-V Hypervisor Logical Processor
C.
Hyper-V Hypervisor Virtual Processor
D.
Hyper-V Hypervisor Root Virtual Processor
Hi Folks,
I would go for A.!
We need the physical processor usage of the host and all of the guests in total, so I think the the processor %processor time would be appropriate, as it delivers the percentage of time, the physical processor spends on working on processes, apart from the idle process.
In my understanding, B. only messures the CPU usage of the virtual machines.
Any comments? Am I right?
Thanks for reply, Michael
Looks like it is B.
Processor:
Once you have an idea of the overall system capabilities and configuration though the “Hyper-V Hypervisor” counter set you will want to monitor the processors on the system. The most important counter set to monitor is the “Hyper-V Hypervisor Logical Processor”. This counter set allows you to determine how much of the physical processor are being used. The virtual processor counter sets only show a slice of the “Hyper-V Hypervisor Logical Processor”.

Measure overall processor utilization of the Hyper-V environment using Hyper-V performance monitor counters – For purposes of measuring processor utilization, the host operating system is logically viewed as just another guest operating system. Therefore, the “\Processor(*)\% Processor Time” monitor counter measures the processor utilization of the host operating system only. To measure total physical processor utilization of the host operating system and all guest operating systems, use the “\Hyper-V Hypervisor Logical Processor(_Total)\% Total Run Time” performance monitor counter. This counter measures the total percentage of time spent by the processor running the both the host operating system and all guest operating systems. Use the following thresholds to evaluate overall processor utilization of the Hyper-V environment using the “\Hyper-V Hypervisor Logical Processor(_Total)\% Total Run Time” performance monitor counter:
