Utilization data is not getting collected for RHEV

Hi Experts,

I have added RHEV Provider, but performance data is not getting collected.

When I select VM and select Utilization tab its grayed.

I have created relation ship for ManageIQ vm, I have added Credentials for Posgress DB , I have enabled CU data utilization for all cluster and Datastore.

Did you enable to C&U roles on the appliance?

Yes, I have done that.

Has your VM been running for atleast 30 days? I think utilization only occurs after 30 days of performance data has been captured. I could be mistaken. Can someone else confirm that Utilization takes 30 days before populating data?
