You must be generally familiar with how to use the Performance Schema feature. For example, you should know how enable instruments and consumers, and how to query performance_schema tables to retrieve data. For an introductory overview, see Section 29.1, “Performance Schema Quick Start”.

You should be familiar with Performance Schema instruments that are available for InnoDB. To view InnoDB-related instruments, you can query the setup_instruments table for instrument names that contain 'innodb'.

mysql> SELECT *
       FROM performance_schema.setup_instruments
       WHERE NAME LIKE '%innodb%';

For additional information about the instrumented InnoDB objects, you can query Performance Schema instances tables, which provide additional information about instrumented objects. Instance tables relevant to InnoDB include:

For example, to view information about instrumented InnoDB file objects seen by the Performance Schema when executing file I/O instrumentation, you might issue the following query:

mysql> SELECT *
       FROM performance_schema.file_instances
       WHERE EVENT_NAME LIKE '%innodb%'\G
*************************** 1. row ***************************
 FILE_NAME: /home/dtprice/mysql-8.4/data/ibdata1
EVENT_NAME: wait/io/file/innodb/innodb_data_file
OPEN_COUNT: 3
*************************** 2. row ***************************
 FILE_NAME: /home/dtprice/mysql-8.4/data/#ib_16384_0.dblwr
EVENT_NAME: wait/io/file/innodb/innodb_dblwr_file

...

You should be familiar with performance_schema tables that store InnoDB event data. Tables relevant to InnoDB-related events include:

If you are only interested in InnoDB-related objects, use the clause WHERE EVENT_NAME LIKE '%innodb%' or WHERE NAME LIKE '%innodb%' (as required) when querying these tables.
