Using Advanced Reporting Reports
The following notes will help you interpret the data listed on the
reports.
• The data for the reports is collected in log files. When the log files
reach their maximum size, the oldest information is deleted as new
information is added. This may affect how much historical data you
can access.
• The on-screen reports contain a chart and a data table. When the
log files are large, it would take an excessively long time to load all
the historical data into the data table. For this reason, the table
displays a maximum of 1000 rows of data, beginning with the most
recent, even if more data is available. (The chart displays
information for the entire range.) To view all of the data, you need
to save or e-mail the data file. See
Saving and E-mailing Advanced
Reporting Data Files on page 125.
• The reports are built according to data in the log files, not your
current library configuration. For this reason, your library may
contain tape drives or cartridges that do not show up in the report.
Similarly, the report may contain tape drives and cartridges that no
longer reside in the library.
• Information about a tape drive, cartridge, or operation is not
recorded in the Drive Resource Utilization log file until after a tape
cartridge has been mounted (loaded)
and
unmounted (unloaded)
from the tape drive.
• To see the exact values of each item in the displayed chart, move
your mouse so that it “hovers” over the item you wish to see. An
information bubble displays with the values listed in it. If you click
on a bar, point, or slice, the information bubble locks in place and
the hovering feature turns off until you reload the chart. The
hovering feature does not work when the value equals zero.
• Values of zero do not appear in Pie charts.
