Hyper-V MPE 2016 Dynamic Memory Average Pressure (Warning)

HyperV.MPE.2016.VirtualMachine.DMAveragePressure.Monitor (UnitMonitor)

Knowledge Base article:

Summary

Warning Threshold.

A virtual machine with a pressure of 100 has exactly the amount of memory that it needs (this is equivalent to a memory availability of 0%). If the virtual machine pressure goes over 100 it has less memory than it needs (equivalent to a negative memory availability) and if the virtual machine pressure is under 100 then the virtual machine has more memory than it needs.
