Names given for filtering operations can be as specific or general as required. To indicate a single instrument or consumer, specify its name in full:

UPDATE performance_schema.setup_instruments
SET ENABLED = 'NO'
WHERE NAME = 'wait/synch/mutex/myisammrg/MYRG_INFO::mutex';

UPDATE performance_schema.setup_consumers
SET ENABLED = 'NO'
WHERE NAME = 'events_waits_current';

To specify a group of instruments or consumers, use a pattern that matches the group members:

UPDATE performance_schema.setup_instruments
SET ENABLED = 'NO'
WHERE NAME LIKE 'wait/synch/mutex/%';

UPDATE performance_schema.setup_consumers
SET ENABLED = 'NO'
WHERE NAME LIKE '%history%';

If you use a pattern, it should be chosen so that it matches all the items of interest and no others. For example, to select all file I/O instruments, it is better to use a pattern that includes the entire instrument name prefix:

... WHERE NAME LIKE 'wait/io/file/%';

A pattern of '%/file/%' will match other instruments that have a component of '/file/' anywhere in the name. Even less suitable is the pattern '%file%' because it will match instruments with 'file' anywhere in the name, such as wait/synch/mutex/innodb/file_open_mutex.

To check which instrument or consumer names a pattern matches, perform a simple test:

SELECT NAME FROM performance_schema.setup_instruments
WHERE NAME LIKE 'pattern';

SELECT NAME FROM performance_schema.setup_consumers
WHERE NAME LIKE 'pattern';

For information about the types of names that are supported, see Section 26.6, “Performance Schema Instrument Naming Conventions”.
