The Operating System Layer

The tests pertaining to the Operating System layer (see Figure 1) report on the physical resource usage by the Hyper-V host – i.e., the root partition in particular. The physical disk drive that is experiencing excessive activity, the disk drive that is low on space, logical/virtual processors that are over-utilized can be identified accurately using the tests mapped to this layer.

We will be discussing the Hyper-V-specific tests only.
