Editing Sar -F

Display [[filesystems usage]] statistics for currently mounted filesystems. Pseudo-filesystems are ignored. At the end of the report, sar will display a summary of all those filesystems.  Use of the MOUNT parameter  keyword  indicates  that mountpoint will be reported instead of filesystem device.  Note that filesystems statistics depend on sadc option -S XDISK to be collected.

* <code>[[sar]] -F</code>
* <code>sar -F --human</code>
* <code>[[for i in]] `ls /var/log/sysstat/sa??`; do sar -f $i -F --human; done</code>



To activate it: <code>sadc</code> option in <code>[[/etc/sysstat/sysstat]]</code> <code>-S [[XDISK]]</code> or <code>-S XALL</code> activated.
