Architecting a vCloud Availability for vCloud Director Solution : vCloud Availability Management Components : 4.11 vCloud Availability Metering
   
4.11 vCloud Availability Metering
Currently VMware vCloud Usage Meter (3.5.x) does not meter vCloud Availability for vCloud Director consumption. While it still needs to be deployed for vCloud Director licensing, it is out of scope for this document.
Instead, a Python usage report script is provided (https://github.com/vmware/vcloud-availability-examples) that enables collection of necessary vCloud Availability for vCloud Director metrics through vCloud API.
The script can be installed on any machine that supports Python and has access to the vCloud API with provider level credentials.
The script provides point in time vCloud organization-level statistics about number of replicated virtual machines and storage capacity the virtual machines consume (including multiple point-in-time snapshots). The data can be exported to json or csv formats for additional processing.
