Using vxstorage_stats
The vxstorage_stats command displays detailed storage mapping information and I/O
statistics about an individual VxFS file. The mapping information and I/O statistics are recorded
only for VxFS files and VxVM volumes.
In vxstorage_stats command output, I/O topology information appears first followed by
summary statistics for each object.
The command syntax is as follows:
/opt/VRTSdbed/bin/vxstorage_stats [-m] [-s] [-i interval
-c count] -f filename
Prerequisites
◆ You must log in as the database administrator (typically, the user ID oracle) or root.
Usage Notes

specified by -i interval.
