By default, the utilization data for the Overall RAID Group utilization metric is displayed in the
Utilization Metrics chart window.
The overall RAID group utilization is the total busy rate of the RAID group over an entire collection
interval. When a RAID group is associated with a ThP pool, this metric provides the extent to

the past one week. For more information on using other chart options, see “Viewing
