Activity Monitor % Processor Time grayed out on SQL Server The % Processor Time graph at Activity Monitor for remote connections stopped working and it grayed out after the physical SQL Server restart (image below), but when I get in the server with the same Domain User it works fine. It was also working fine on remote connections before the restart and I have noticed that it takes significantly more time to load the Processes than before.



The problem is happening to all users that try to see the Processor Time remotely including sa and server admins so I would think it´s not a permission issue. The server runs Windows Server 2012 and SQL Server 2012.

What could be happening? or How can I solve this?

Thanks in advance! and sorry about my English.
I know it is not a solution but we had a programmed restart and after that everything works fine, it is a production server so we couldn't restart before but that solved it.
