The Disk Usage page shows the historical usage and projected data growth of all logical disks 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.
