LowLevel 2Automatedmysql

Description

A value of 2 enables logging of error and warning messages, a value of 3 also includes informational logging, a value of 1 logs only errors. Runs mysql -NBe with the client defaults: put an administrative account in ~/.my.cnf (mode 0600) or a mysql_config_editor login path, not MYSQL_PWD (see 1.4/1.6).
