Ksar (Unix sar grapher)
Ksar is a BSD-licensed Java-based application that creates graphs of all parameters from data collected by Unix sar utilities. Usually, Unix sar is part of Unix' Sysstat package, and runs sa1, sa2, and sadc through cron to created data files in /var/log/sa/saNN. Characteristics include:
- Images can be zoomed by dragging the mouse on an image to pinpoint problems
- Results can be exported to PDF or JPEG format

Generating SAR Text Files for Ksar Use
- To begin gathering sysstat history information for use of the sar command, systat should be configured to run through cron (preferably every minute). More instructions are available on the 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] | sed 's_/var/log/sa/sa_ _g' | xargs)
