Is the allocation of physical resources relative to virtual machines monitored?
Precisions
Virtualization techniques make it possible to pool the physical resources of a server and a storage space. This abstraction can optimize the use of equipment, but can also lead to underutilization of physical equipment and to a deployment of new equipment before the need is really present. The total environmental footprint of a server and its use is significant.
Use Case
Hosting technical documentation allow to follow up configuration sizing compared to usage

Rule for assessing the level of compliance of the criterion
Taux utilisation VM > 60 = 100 ; 60-40 = 50 ; < 40 = 0 / 100
