您必須大致熟悉如何使用Performance Schema 功能。例如，您應該知道如何啟用工具和取用者，以及如何查詢 performance_schema 資料表以擷取資料。如需簡介，請參閱第 29.1 節， 「Performance Schema 快速入門」。

您應該熟悉可供 InnoDB 使用的 Performance Schema 工具。若要檢視與 InnoDB 相關的工具，您可以查詢setup_instruments 資料表，以取得包含 'innodb' 的工具名稱。

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

如需有關檢測 InnoDB 物件的其他資訊，您可以查詢 Performance Schema 實例資料表，其中提供有關檢測物件的其他資訊。與 InnoDB 相關的實例資料表包括

例如，若要檢視 Performance Schema 在執行檔案 I/O 工具時看到的檢測 InnoDB 檔案物件的相關資訊，您可以發出下列查詢

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

您應該熟悉儲存 InnoDB 事件資料的 performance_schema 表格。與 InnoDB 相關的事件表格包括：

如果您只對與 InnoDB 相關的物件感興趣，請在查詢這些表格時使用子句 WHERE EVENT_NAME LIKE '%innodb%' 或 WHERE NAME LIKE '%innodb%'（根據需要）。
