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.
sar -Fsar -F --humanfor i in `ls /var/log/sysstat/sa??`; do sar -f $i -F --human; done
Usage filesystem /dev/root at the end of the day:
for i in `ls /var/log/sysstat/sa??`; do echo "DAY:$i"; sar -f $i -F --human; done | egrep "/dev/root|DAY" | awk '{print $1" "$3}' | egrep "DAY|00:10"
To activate it: sadc option in /etc/sysstat/sysstat -S XDISK or -S XALL activated.
