For the Real User Collector to report information about your virtual machines (VMs) and the computers that host them, you must configure a connection between the system and a VM manager, such as a vCenter console or a stand-alone ESX server.
For the system to be able to identify your virtual machines (VMs), you must ensure the following:
Without the necessary privileges, the system cannot access the data that it needs for reporting.
To perform this procedure, you must have Operator-level access, or higher.
In the Description text box, type a description to distinguish the vCenter from other VM managers in the system.
(Optionally) Select the Allow self-signed certificate and Use secure connection check boxes.
In the Port box, type 443.
In the User name and Password boxes, type the credentials to access your vCenter.
The ESX server appears in the list of VM managers. The system displays a check mark icon for the new VM manager after it establishes a connection. If there is already another VM manager (a vCenter) that manages the ESX server that you add, the system displays a warning icon.
Here, you can verify whether the system has identified all VMs managed by a given VM manager and find VMs without VMware Tools installed.
