sfxstat [ -abcdfilmA ] [ interval [ count ] ] [ mount_point ... ]
The sfxstat command displays the statistical information on the GFS Local File System.
sfxstat 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, sfxstat 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, sfxstat 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, sfxstat reports statistical information on the specified file system. When no mount_point specified, sfxstat reports statistical information on all mounted GFS Local File System.
When the option is omitted, reports all available information.
