Open_files

归隐乡村

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.

看手册上有这么一段话

我有点好奇
the count does not include files that storage engines open using their own internal functions  这些文件是什么文件

    没有研究过，个人认为可能是引擎特殊管理的文件，比如 innodb 的 ibdata ib_logfile 之类的文件，仅是推测，希望有了解的同学指点指点。
