The Processes report lists the processes currently running on the selected MySQL instance, with their Thread ID, User, and so on.
This report requires sys schema be installed on the selected MySQL instance. If sys is not installed, and the selected instance is compatible, you are prompted to install it.
This graph is displayed only if a MySQL instance is selected in the All Targets drop-down menu.
