sfcstat [ -abcdefghijklmnopqrstA ] [ interval [ count ] ] [ mount_point ... ]
The sfcstat command displays statistics about GFS Shared File Systems.
sfcstat first 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 no interval specified, it reports on statistical information only once.
When the parameter count is specified, sfcstat reports statistical information for the interval it takes to count to count. When no count specified, it keeps displaying statistical information.
When the parameter mount_point is specified, sfcstat reports statistical information on the specified file system. When no mount_point specified, sfcstat reports statistical information on all mounted GFS Shared File System.
The following options can be specified:
If the options are omitted, the command reports all information.
