[CentOS] reading sar data

[muhammad panji]

Hi,
I have a problem reading sar data. I have some server but no
monitoring tools like cacti or nagios on it. every end of month I got
the sar log manually and have to generate report for it but I have no
idea how to read it. on this page
:http://pagesperso-orange.fr/sebastien.godard/tutorial.html i found
there is tool called sadf, can i use it on CentOS 4 or it just
available on Centos 5? I found sadf on centos5 but not on centos 4.

are there any tools that could be used to generate a graphic from a
month historical sar data?
best regards,
