I try to graph performance by ksar. In my CentOs machines I do the following:
for i in /var/log/sa/sa??; do sar --legacy -A -f $i >>monthly; done
ksar -input 'file:////root/monthly'
That show me all the 30 days -- but, in OpenSuse ksar show me only one day.
Here some experiences I try with no success:
for i in /var/log/sa/sa??; do sar -A -f $i >>monthly; done
or
cat /var/log/sa/sar?? >> monthly
or
scp root@aCentosMachine:monthly .
Any idea? Is it a bug?
Unfortunately the answer is bad.

Known issues
Sometime due to unknown reason multiple day graphs are not being generated.
So it is a bug and I am luck that I can do multiple day on Centos
