The image below shows a typical virtualized environment with VMware. In this environment, the ESX/ESXi hypervisor on each individual host server collects the performance statistics and reports the data back to a central vCenter Server. SQL Diagnostic Manager then collects that information from the vCenter Server in order to show those statistics along with the other SQL related performance information.
In virtualized environment with Hyper-V, the process of how SQL Diagnostic Manager collects and presents metrics is slightly different from that of a VMware setup. In this environment, SQL Diagnostic Manager collects all the required performance statistics from the Hyper-V host server and virtual machines using the WMI interface. See Hyper-V user requirements for information on how to successfully collect host and VM metrics.
