Generating sar text file for Ksar use
- To begin gathering sysstat history information for use of sar command, systat should be configured to run through cron (preferably every minute). More instruction are available on systat web site.

- Generating sar text file with all system resources information
DT="10" LC_ALL=C sar -A -f /var/log/sa/sa$DT > /tmp/sar-$(hostname)-$DT.txt ls -l /tmp/sar-$(hostname)-$DT.txt
- Generating only disk information from a sar data file
(Note that sar will collect disk information only if sadc is running with -d option thru cron)
DT="10" LC_ALL=C sar -d -p -f /var/log/sa/sa$DT > /tmp/sar-$(hostname)-$DT.txt ls -l /tmp/sar-$(hostname)-$DT.txt
- Generating a text file for multiple days
DT="12 13 14" >/tmp/sar-$(hostname)-multiple.txt for i in $DT; do LC_ALL=C sar -A -f /var/log/sa/sa$i >> /tmp/sar-$(hostname)-multiple.txt done ls -l /tmp/sar-$(hostname)-multiple.txt
For getting all the days in the default folder, you can replace the harcoded DT variable with:
DT=$(ls /var/log/sa/sa[0-9][0-9] | tr '\n' ' ' | sed 's/\/var\/log\/sa\/sa/ /g')
