To collect accurate usage data, vCloud Usage Meter requires specific configuration of the metered vCenter Server instances.

Lookup Service

The vCloud Usage Meter appliance connects to the single sign-on server (lookup service) before connecting to a vCenter Server. If the lookup service does not reside on the same vCenter Server, enter the IP address of the single sign-on server when registering your vCenter Server in the vCloud Usage Meter Web application. The vCloud Usage Meter assumes that the default port number of the lookup service is 7444.

If you do not meet the vCenter Server requirement, all vCenter Server collections fail with the following error message in the Monitor tab of the Web application: vCenter Server connection failed. Please make sure that vCenter Server SSO service is up, and it is NTP configured.

vCenter Server Clusters

Service providers normally host customer and administrative virtual machines on a single vCenter Server. Tenants consume compute resources from the customer virtual machines, whereas service providers use the administrative virtual machines for internal purposes. To ensure accurate reporting to service providers and to VMware, you must apply a degree of segregation between customer and administrative virtual machines. The best practice is to create a dedicated cluster for both types. For example, create a Customer cluster to host all customer VMs and a Management cluster to host all VMs vital to the service provider business operations. The separation of VMs based on their function ensures that vCloud Usage Meter reports do not contain usage data for mixed customer and administrative VMs.

ESXi Licenses

After you create dedicated clusters for VMs based on their functions, you must assign proper ESXi licenses to the cluster hosts. Select VCPP license for both Customer and Management clusters. For more information, see License Sets and Billing Categories and Manage Billing Categories.
