Drive Resource Utilization Report
The Drive Resource Utilization Report provides tape drive usage information, showing you which tape drives are working at optimum capacity and which are under-utilized. This can help you allocate your tape drive resources properly.
You can only access this report if you have Advanced Reporting licensed on the library (see Applying a License Key). For more information on how the Advanced Reporting feature works, see About Advanced Reporting.
Generating the Report
- From the Reports menu, select Advanced Reporting > Drive Resource Utilization.
The Drive Resource Utilization Report configuration page opens. This might take several minutes.
- Configure the settings to create the report you want.
-
- Range — Specifies the range of time covered by the report. Choose Last 7 days; Last 4 weeks (default); Last 3 months; or All History (as far back as there is data in the log file).
- Attribute — Specifies which value is included in the report. Select one of the following:
- Data Written/Read (default) — The amount of data written to and read from each tape drive, shown separately in the chart.
- Total Read and Write — The combined total amount of data written to and read from each tape drive.
- Media Mount Count — The number of tape cartridge mounts.
- Media Mount Time — The total amount of time media spent in the selected drive(s).
- Media Motion Time — The total amount of time media spent in motion while in the tape drive (writing, reading, rewinding, etc.).
- Grouping — Specifies which tape drive(s) or partition(s)to include in the report. Select one of the following:
- All Drives by Coordinate (default) — Presents the sum total of the selected attribute for all tape drives according to their location in the library. If more than one tape drive resided in that location during the selected range, then the attribute values for all the tape drives that resided in that location are combined in the chart.
- All Drives by Physical SN — Presents the sum total of the selected attribute for all drives according to the physical tape drive serial number.
- All Partitions — Presents a comparison of all drives grouped by partition in the physical library.
- Selected Drive by Coordinate — The report chart is based on an individual tape drive location in the library. If more than one tape drive resided in that location during the selected range, then the attribute values for all the tape drives that resided in that location are combined in the chart.
- Selected Drive by Physical SN — The report chart is based on an individual tape drive identified by its physical drive serial number.
- Selected Partition — The report chart is based on an individual partition in the physical library.
- Chart — How the data is displayed in the chart. Choose Area, Bar (default), Line, or Pie.
- Type — The chart type. Select one of the following:
- Rollup (default) — Displays the Grouping on the x-axis and the Attribute amount on the y-axis.
- Trend — Shows how the Attribute amount changes over time for the selected Grouping.
- Click Next.
The report is generated and appears onscreen. The chart contains all of the data for the range you selected. (Values of zero do not appear in pie charts.)

NOTE: Due to long load times, the table under the chart only contains data for the past seven days. If you need to see the entire data set, you need to save the data file (see Saving and E-mailing Advanced Reporting Data)
|
 |
NOTE: It is possible to have tape drives listed in the report that no longer reside in the library. Also, an action or item may not appear in the report if the cartridge has not been unmounted from the tape drive. See About Advanced Reporting for more information.

-
To see the exact x- and y-axis values of each item in the chart, move your mouse so that it "hovers" over the item you wish to see. An information bubble appears 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.
 |
NOTE: The hovering feature does not work when the value equals zero.
