Creating a Logical Disks Space Report
The Logical Disks Space report displays total and raw logical disk space over a selected time
interval. The X-axis (category) represents time, and the Y-axis (value) indicates the amount of logical

on the same chart.

The date and time usage information was collected. (Shown only for values over time chart
types.) Time
