Scalable Licensing in vRealize Operations : Tenant Monitoring with a Single vRealize Operations Instance : 3.3 Configuration
   
3.3 Configuration
3.3.1 Service Account Configuration
Monitoring a subset of VMs is accomplished using permissions assigned to the vRealize Operations service account at key locations in vCenter Server. For example, the VM folder that corresponds to an Organization VDC in VMware vCloud Director® automatically monitors all VMs provisioned within that Organization VDC.
Figure 4. Example Showing Permissions Assigned to Monitor All VMs in an Organization VDC
Follow these steps to set up permissions and see https://kb.vmware.com/kb/1036195 for additional details:
1. Create a service account for vRealize Operations to collect data from vCenter Server.
2. Clone the “Read-only” role in vCenter Server.
3. Add privileges to the new role:
Global / Health
Profile-driven storage / Profile-driven storage view
Storage views / View
4. Assign permissions in vCenter Server to the appropriate vCenter Server objects using the new role. Table 2 offers some suggested locations to assign permissions.
5. Log in to vCenter Server using the service account to verify that the desired objects are visible.
Note Visibility of some objects require that permissions are assigned to the object’s parent. If an object is not visible in the VMware vSphere® Client™, assign permissions to the parent of the object with propagation disabled.
