To get an estimate without installing a trial version of Foglight Evolve, here are some options to count VMware and Hyper-V hosts and to make an estimate in a Foglight Evolve environment.
VMware. Using the vSphere client, connect to each vCenter and click on the top of the tree and click Summary. Hyper-V. Microsoft Technet offers a Get-SCCVMInventory Power Shell script that runs on a SCVMM server. From the Q&A, the latest version can be found at a Power Show Gallery dot com.
