sfcstat [ -abcdefghijklmnopqrstuvwA ] [ interval [ count ]] [ mount_point ... ]
The sfcstat command displays statistics about the GFS Shared File Systems.
The sfcstat is used without parameters, it reports statistical information recorded after the file system is mounted. The next time, it reports the information recorded since the last report.
When the parameter interval is specified, sfcstat reports statistical information for the interval that was specified in this parameter (in seconds).
When the parameter count is specified, sfcstat reports statistical information for the interval it takes to count to count.
When the parameter mount_point is specified, sfcstat reports statistical information on the specified file system.
