M. Fields Affected by Setting the PFM - RM for Virtual Machine

The following describes the fields affected by setting described at 2.1.4(2) Setting PFM - RM for Virtual Machine. An example is shown below and the table shows the different values for each setting.

The example monitoring target is as follows:

VMware: Hyper-Threading is enabled

CPU: Physical processor for 1 core: 2GHz.

Number of physical processor cores: 2

Number of logical processor cores: 4

CPU resources used: 3GHz
