HP 3PAR Operating System Software - Manual (Page 367)

The first chart (displayed on the left side of the Management Window) shows the total space used
by the region during the specified time period. Each region is put into the appropriate histogram
bucket on the X-axis (category) based on its IO access rate during the specified time period. The
Y-axis (value) for this chart indicates the total space for the regions in the histogram bucket.
The second chart (displayed on the right side of the Management Window) shows the regions’
total IO accesses/minute during the specified time period. The X-axis for this chart follows the same
convention as the first chart. The Y-axis for the second chart indicates the total IO accesses/minute
for the regions in the histogram bucket.

Fine – Provides the most granular level of detail (for example, 1, 2, 4, 8 IO/(GiB*min), and
so on).
Medium – Provides a medium level of detail (for example, 1, 4, 16, 64 IO/(GiB*min), and
so on).
Coarse – Provides a compact level of detail (for example, 1, 8, 64, 512 IO/(GiB*min), and
so on).
5. In the Time Interval group box, select a Start Time and End Time. If you keep the default end
