Hyper-V host and VM metrics are available through the same WMI path used for other Windows Server monitoring, plus Hyper-V's own WMI namespace.
Add the Hyper-V host as a standard Windows/WMI device first and confirm basic host metrics report, before layering on Hyper-V-specific polling.
Under the device's settings in Linivo, enable the Hyper-V extension, which polls the host's Hyper-V WMI namespace for per-VM CPU, memory and disk metrics in addition to the base OS metrics.
Once enabled, each VM on the host shows up as its own set of metrics rather than folding into the host's aggregate numbers, useful for finding which specific VM is driving a host's CPU spike.
