What access level is needed to monitor processes in "Run time Data"?

I was wondering what level access is needed to be able to monitor processes from the runtime data screen.

I have a particular user who is of type "basic user" and is part of the "Designers" group so it can access the runtime data screen and view the process list but is unable to monitor the processes. I would like for this user to be able to do so.

Any ideas on how to achieve this?
