4.9 Display statistics
iXOS-JUKEMAN allows to print statistics about device and disk accesses.
There are three types of statistics:
• the amount of transferred data and disk moves concerning the disks in
all controlled devices
• the amount of transferred data and disk moves concerning the disks in
a specific device
• The amount of transferred data and disk moves concerning the disks
in one device (summed up)
The values are with regard to the running server process. To view the
statistics for a specific disk, sort the list by disk names. One of the follow-
ing name formats may be selected: PC format, Rock Ridge format, High
Sierra format, and original disk name.
To find out which disks are accessed most frequently, the list can be
sorted appropriately. 'Reads' is the number of read accesses to data
blocks of 64kB maximum.
The value 'moves' is the number of moves of a disk into a drive of a juke-
box. If this number is very large the overall performance may be improved
by inserting the disk into a separate CD-ROM drive or tower.
