The file instances Table-opracowanie

The file instances Table
The file_instances table lists all the files seen by the Performance Schema when executing file I/O
instrumentation. If a file on disk has never been opened, it will not be in file_instances. When a file
is deleted from the disk, it is also removed from the file_instances table.
The file_instances table has these columns:
• FILE_NAME
The file name.
• EVENT_NAME
The instrument name associated with the file.
• OPEN_COUNT
The count of open handles on the file. If a file was opened and then closed, it was opened 1 time, but
OPEN_COUNT will be 0. To list all the files currently opened by the server, use WHERE OPEN_COUNT
