Hosts dashboard is not displaying all the data for either VMWare ESX hosts / virtual machines or Microsoft Hyper-V hosts / virtual machines
Hosts dashoard is meant for Physical hosts and not for VMs and that is why we created VMware Explorer / Hyper-V Explorer dashboards since that provides correct data for virtual machines. The reason why VMs are seen in Hosts dashboard is because we store Data in two different data models - Hosts model and VMware model. This is by design of the product itself.
As far as Network and Disk utilization values being "n/a" in Hosts dashboard, it is a known issue for the same reason mentioned above and is documented as Defect ID VM-559 in the Release notes of VMware cartridge and as Defect ID HV-196 in the Release notes of Hyper-V cartridge.
Use the VMware Explorer / Hyper-V Explorer dashboards for reviewing data for Virtual Machines.
