Chargeback is an important feature for computing infrastructures. Even inside an enterprise where IT users are not charged with real money, it’s still nice to see the usage patterns and sometimes avoid wasting resources. As I mentioned in IBM RC2, applying chargeback reduced unnecessary usage overnight.
VMware vCenter Chargeback is a component for this purpose. It can run standalone with Web GUI, and surface to vSphere Client as a plug-in. Although its name includes vCenter, it can also work with vCloud Director (see Using vCenter Chargeback with VMware Cloud Director).
