Open_files

歸隱鄉(xiāng)村

The number of files that are open. This count includes regular files opened by the server. It does not include other types of files such as sockets or pipes. Also, the count does not include files that storage engines open using their own internal functions rather than asking the server level to do so.

看手冊上有這么一段話

我有點好奇
the count does not include files that storage engines open using their own internal functions  這些文件是什么文件

    沒有研究過，個人認(rèn)為可能是引擎特殊管理的文件，比如 innodb 的 ibdata ib_logfile 之類的文件，僅是推測，希望有了解的同學(xué)指點指點。
