The Disk Health Report features a Double-Bar Graph that graphically displays the Max and Current drive space.
About the Disk Health Report
The Disk Health Report is home to a Double-Bar Graph that shows the user the Max Size and Current Usage of every selected Drive on every selected Server.
The report itself can be modified by 2 different filters:
Servers
Displayed Disks (All Disks, or only Monitored Disks)
Once the filters are applied, the histogram bar graph can be drilled down even further by clicking on the individual states in the legend at the bottom. This will hide/show those states from the histogrambar graph.
