A managed process is a process that will be automatically restarted and recovered by ClusterControl.
Under "Process Management" (click on Proc mgmt on the right hand sidebar), you will see the processes that ClusterControl governs.
It may take a while (a couple of minutes) for the list to be populated. If it is empty you can also try and restart the CMON Controller.
Before the list is populated ClusterControl will not be able to perform recovery.
