The Disk Usage page shows the historical usage and projected data growth of all logical disks and mount points across your monitored estate.

Understanding the Disk Usage page

The screenshot below shows an example of the data displayed on this page:

The graph spans from 1 year ago to 1 year in the future, centered on the date the page was viewed. Two lines are shown:

The cumulative historical disk usage for your entire estate over the past 12 months (blue).
The linear trend line projecting data growth across your entire estate for the next year based on the historical usage (orange).

This summary pane shows cumulative metrics for all disks across the entire monitored estate:

Metric title	Metric description
Current space used	The total current used disk space.
Current capacity	The total current disk capacity.
Projected size	The total projected size of the data in 12 months' time.
Projected change	The total projected change in data size over the next 12 months.

This table shows the detailed metrics for every individual logical disk across the entire monitored estate:

Metric title	Metric description

Percentage used	Space used / Capacity
Projected space used	The projected size of the data on the disk in 12 months' time.
