V$ASM_DISKGROUP_STAT displays performance statistics in the same way that V$ASM_DISKGROUP does, but without performing discovery of new disk groups. This results in a less expensive operation. However, since discovery is not performed, the output of this view does not include any data about disk groups that are new to the system.
The columns for V$ASM_DISKGROUP_STAT are the same as those for V$ASM_DISKGROUP.
