Files / DiskFile Entity

                         see System Quirks        

The Files / DiskFile Entity screen presents information about the MEASURE DiskFile entity.

The MEASURE DiskFile entity displays one record for each open (or active) file on a disk volume.  This can be considered the next level down from the Disk Entity.

This is an approach to consider when diagnosing disk drive performance issues:

• Drill down starting at the volume level, working down sequentially through the DiskFile, DiskOpen and finally to the process level.

• Starting from the Disk Entity screen, click on a volume and select DiskFile Entity to see all of the active files on the disk.

• On an entry on the DiskFile Entity screen, click to select DiskOpen Entity which displays all of the processes accessing the file.

• On an entry on the DiskOpen screen, click on the Opener Process Name to view Process Detail of the opener process of that file.  (you can also click on the File Name to view the File Entity which provides different I/O counters).
