4.3.2 vRealize Operations for Tenant Monitoring
vRealize Operations instance for each tenant can be configured to monitor all VMs or a subset. To monitor as subset of VMs, use the procedure described in Section 3.3, Configuration.
Note vCloud Usage Meter uses the vCenter Server web client registration to identify vCenter Server to vRealize Operations relationships. The tenant vRealize Operations instances must be registered with vCenter Server to be metered correctly.
Caution Multiple vRealize Operations instances collecting from a single vCenter Server puts additional stress on the vCenter Server. Proceed with caution and monitor vCenter Server performance.
