始终可以通过检查 setup_instruments表来确定性能模式包含哪些工具。例如，要查看为InnoDB存储引擎检测了哪些与文件相关的事件，请使用以下查询：

mysql> SELECT NAME, ENABLED, TIMED
       FROM performance_schema.setup_instruments
       WHERE NAME LIKE 'wait/io/file/innodb/%';
+-------------------------------------------------+---------+-------+
| NAME                                            | ENABLED | TIMED |
+-------------------------------------------------+---------+-------+
| wait/io/file/innodb/innodb_tablespace_open_file | YES     | YES   |
| wait/io/file/innodb/innodb_data_file            | YES     | YES   |
| wait/io/file/innodb/innodb_log_file             | YES     | YES   |
| wait/io/file/innodb/innodb_temp_file            | YES     | YES   |
| wait/io/file/innodb/innodb_arch_file            | YES     | YES   |
| wait/io/file/innodb/innodb_clone_file           | YES     | YES   |
+-------------------------------------------------+---------+-------+
