New Post: Memory demande on VM dynamic memory

Hi
I'm looking for to find the "memory demand" of a VM on a Hyper-v with a automatic program. I found the other counters like "Assigned Memory" using the wmi request on winmgmts:\\$computer\root\virtualization
Msvm_ComputerSystem
Msvm_MemorySettingData
Msvm_Memory

some web site said
Assigned Memory = Memory Demand + (Memory Demand x Memory Buffer/100)
But I find some example where this formula is not correct.

So if some one can help me, i will be very thankful
