Performance Schema Quick Start information. For example, the  file_instances  table lists instances of instruments for file I/O operations and their associated files: mysql>  SELECT * FROM performance_schema.file_instances\G *************************** 1. row ***************************  FILE_NAME: /opt/mysql-log/60500/binlog.000007 EVENT_NAME: wait/io/file/sql/binlog OPEN_COUNT: 0 *************************** 2. row ***************************  FILE_NAME: /opt/mysql/60500/data/mysql/tables_priv.MYI EVENT_NAME: wait/io/file/myisam/kfile OPEN_COUNT: 1 *************************** 3. row ***************************  FILE_NAME: /opt/mysql/60500/data/mysql/columns_priv.MYI EVENT_NAME: wait/io/file/myisam/kfile OPEN_COUNT: 1 ... mysql>  SELECT NAME, ENABLED, TIMED FROM performance_schema.setup_instruments; +---------------------------------------------------+---------+-------+ | NAME | ENABLED | TIMED | +---------------------------------------------------+---------+-------+ ... | stage/sql/end | NO | NO | | stage/sql/executing | NO | NO | | stage/sql/init | NO | NO | | stage/sql/insert | NO | NO | ... | statement/sql/load | YES | YES | | statement/sql/grant | YES | YES | | statement/sql/check | YES | YES | | statement/sql/flush | YES | YES | ... | wait/synch/mutex/sql/LOCK_global_read_lock | YES | YES | | wait/synch/mutex/sql/LOCK_global_system_variables | YES | YES | | wait/synch/mutex/sql/LOCK_lock_db | YES | YES | | wait/synch/mutex/sql/LOCK_manager | YES | YES | ... | wait/synch/rwlock/sql/LOCK_grant | YES | YES | | wait/synch/rwlock/sql/LOGGER::LOCK_logger | YES | YES | | wait/synch/rwlock/sql/LOCK_sys_init_connect | YES | YES | | wait/synch/rwlock/sql/LOCK_sys_init_slave | YES | YES | ... | wait/io/file/sql/binlog | YES | YES | | wait/io/file/sql/binlog_index | YES | YES | | wait/io/file/sql/casetest | YES | YES | | wait/io/file/sql/dbopt | YES | YES | ... mysql>  UPDATE performance_schema.setup_instruments SET ENABLED = ’NO’ WHERE NAME = ’wait/synch/mutex/sql/LOCK_mysql_create_db’; To understand how to interpret instrument names, see Section 27.6, “Performance Schema Instrument Naming Conventions” . To control whether events are collected for an instrument, set its  ENABLED  value to  YES  or  NO . For example: 4900 Setup tables are used to configure and display monitoring characteristics. For example, setup_instruments  lists the set of instruments for which events can be collected and shows which of them are enabled:
