Drill through​

Clicking on an entry in the table will drill through to the z/OS Unix File Activity report using the system and device number. This allows you to see the file activity in that file system including file level I/O statistics.

Note: If the selected time includes an IPL the file system device number might be reused for a different file system. In this case the file activity for both filesystems using the same device number would be shown.
