			And run the following commands in the local ProxySQL admin session:

			UPDATE global_variables SET variable_value='monitor' WHERE variable_name='mysql-monitor_username';
			UPDATE global_variables SET variable_value='MONITOR-PASSWORD' WHERE variable_name='mysql-monitor_password';

			Make sure you add monitor users to the back end database, ensure firewalls allow the connection through etc.
