[ Thanks to Falko
for this link. ]

“sar is one of the old and famous commandline
utilities, which is often overlooked. It provides a wealth of
information when you have kind of performance bottlenecks. By
itself it only provides lengthy columns of numerical data, kind of
hard to interpret. sar exists on most Linux distributions, for
example Ubuntu, Debian, CentOS, Gentoo, and is also available on
Solaris, AIX, and other commercial Unices.

“ksar, on the other hand, is a Java based front end for sar’s
numerical data. It produces friendly graphs which could be exported
to .pdf and some other formats.

“Preliminary Note + Disclaimer
