Debugging mode in MySQL Workbench
To see all queries sent to a server check the general/slow query log (it must be activated for that server, of course).
Alternatively, for these graphs check the source code of MySQL Workbench. Use the labels below the graphs to find a location in code. For example the &quot;InnoDB Buffer Usage&quot; graph is created in plugins/wb.admin/Frontend/wb_admin_monitor.py. Study the code to learn which variables are queried to get series of values.
