Device reports

Device reports provide information about the way devices are being used. They show scheduled and manual backup activity on one or more selected devices over time. You can identify periods of heavy activity or inactivity. Device reports aid NetWorker administrators in performance tuning, and they help identify bottlenecks. For example, if all drives are being used continuously for a long period, at maximum throughput, backup speeds may improve by adding tape drives or moving clients to another backup server.

Types of Device reports and configuration

The Devices report category includes only one report, the Drive Utilization report. This report, which is a drill-down report, supports NetWorker servers running NetWorker software release 7.3 or later. These versions are now unsupported. The report includes backup activity data for all device types, including advanced file type devices and digital data storage devices.

When viewing a Drive Utilization report as a chart, it is automatically displayed as a Gantt chart, where the backup activity level of one or more devices is depicted in relation to time. Unlike with other reports, you cannot choose an alternate chart type.

Placing the cursor over the chart in Save Set view displays a tool tip that provides this information:

  • Save set name
  • Start time
  • End time
  • Client name
  • Throughput value

Placing the cursor over the chart in Drive View displays a tool tip that provides this information:

  • Drive
  • Start time
  • End time
  • Throughput value
NOTE:One of the activities in the Drive Utilization report is throughput. Since the Drive Utilization Report provides data for backup activities only, throughput values will normally be non-zero. However, zero (0) is considered a valid throughput value.
