Just to clarify:
VMware highly recommends customers to benefit from CapacityIQ's analysis for their entire vSphere environment.
As a result, CapacityIQ is always enabled for all VMs in the vCenter instance to analyze, optimize and forecast capacity for the use of the virtual infrastructure. Regarding licensing, customers can still license CapacityIQ for a subset of their virtual environment today, although there is no way to indicate that in the product currently. We expect customers to use the product in compliance to the licensing terms.
1. Is it possible to license CapacityIQ for a subset of my vCenter inventory?
Yes.
E.g. You can apply and use, say, a 50 VM license of CapacityIQ for your 2 production clusters, even if your vCenter inventory has 200 VMs.
2. Will I be out of compliance if I am using CapacityIQ with a 50 VM license against a 200 VM vCenter inventory?
No, as long as you are truly using CapacityIQ analysis for the count of VMs it is licensed for.
3. Is there a way in the CapacityIQ product today to select for analysis or report license usage on a specific subset of clusters or VMs?
No.
vCenter License Reporting Manager will show the total VM license capacity and the assigned license VM count of all VMs in the associated vCenter.
