Running MySQL database user queries/processes on a cPanel account can be checked either via SSH or through the command line in cPanel under Advanced -> Terminal. As an exception, running processes must be checked per database user, because permission management works differently on the MySQL server. Unfortunately, it is not possible to check the processes/queries of all related database users using the main cPanel account.
To check processes/queries per database user, enter the following command in the command line:
mysql -u DB_USERXX -p -e "SHOW FULL PROCESSLIST;"
or
mysql -u DB_USERXX -p -e "SHOW PROCESSLIST;"
(where DB_USERXX is the specific database user whose processes you want to check.)
