### Example metric

## Useful queries
Percent of physical CPU resources used per VM (on instance "localhost")
```
(sum (rate(windows_hyperv_hypervisor_virtual_processor_mode_time_total{state="hypervisor",instance="localhost"}[1m]))) / ignoring(state,vm) group_left max (windows_cpu_logical_processor{instance="localhost"}) / 100000
```
Percent of physical CPU resources used by all VMs (on all monitored hosts)
```
(sum by (instance)(rate(windows_hyperv_hypervisor_virtual_processor_run_time_total{}[1m]))) / max by (instance)(windows_cpu_logical_processor{}) / 100000
```
Percent of physical CPU resources by the hosts themselves (on all monitored hosts)
```
(sum by (instance)(rate(windows_hyperv_hypervisor_root_virtual_processor_time_total{state="total"}[1m]))) / sum by (instance)(windows_cpu_logical_processor{}) / 100000
```
Percent of physical CPU resources by the hypervisor (on all monitored hosts)
```
(sum by (instance)(rate(windows_hyperv_hypervisor_logical_processor_time_total{}[1m]))) / sum by (instance)(windows_cpu_logical_processor{}) / 100000
```
