vCloud Usage Meter is a virtual appliance that you deploy with vSphere Web Client. To set up the virtual appliance, you must set the required passwords, configure your network, and add a vCenter Server instance for metering.
To manage who can use the application, you can set up an LDAP authentication.
The size of your data set and the vCenter Server inventories that vCloud Usage Meter meters affect the speed of a consumption data collection. For large data sets and vCenter Server inventories, consider deploying more than one vCloud Usage Meter appliances.
To avoid configuration problems and ensure accurate metering of products, you must synchronize the vCloud Usage Meter date and time with the date and time of the metered products. As a best practice, use the same NTP server for the vCloud Usage Meter appliance and the metered products.
