I would like to see the Reporting tab for the vRAM usage, but If I click on the Reporting Tab under Home > Administration > Licensing I get this error message:

An internal System Error was occured

Solution

Connect to the vCenter Appliance over SSH

and type

#/usr/lib/vmware-vsphere-client/scripts/admin-cmd.sh unregister https://<hostname>:9443/vsphere-client localhost root "Password"

#/usr/lib/vmware-vsphere-client/scripts/admin-cmd.sh register https://<hostname>:9443/vsphere-client localhost root "Password"

and make sure that the Flash Player is installed.

Now the Reporting Tab should work.
