Therefore i remind visitor do not use "Task Manager".
In order for you to correctly measure the Virtual Machine, you can use Performance Monitor which available on Hyper V Host machine. Configure Data Collector Set and enter below counter to collect the report.
i) CPU Utilization:-
a) For Physical Server
Hyper-V HyperVisor Logical Processor (*)\% Total Run Time
Sample of a Hyper V physical host:-
b) For Virtual Machine
Hyper-V HyperVisor Virtual Processor\% Guest Run Time
- select vcpu of the virtual machine.
Sample of a virtual machine with 2vcpu:-
Sample of DPM VM with 4vcpu:-
ii) Memory Availability
a) \Memory\Available Mbytes
iii) Disk Utilization
a) \Logical Disk (*)\Avg Disk Sec /Read
b) \Logical Disk (*)\Avg Disk Sec /Write
Sample of Virtualization host:- memory and disk utilization
Look nice the graphic but sometimes not 100% accurate. Refer to the average value and below benchmark to interpret the result of the performance collection.
Healthy : Less than 75%
Warning : Greater than 75%
Critical : Greater than 85% (need to investigate)
Healthy : Greater than 10% of RAM
Warning : Less than 10% of RAM
Critical : Less than 100MB
Healthy : Less than 10 ms (0.010)
Warning : Greater than 15 ms (0.015)
Critical : Greater than 25 ms (0.025)
