System Monitoring With sar And ksar

Jan 30, 2011, 19:04 (3 Talkback[s])

[ Thanks to Falko Timme 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

"For using this tutorial you should be familiar using a shell, at least some basic knowledge is advantageous.

"The following tutorial is a kind of cooking receipe using sar and ksar. It should easily be adoptable to nearly any kind of Linux or Unix, where the prerequisites are available. I can not issue any guarantee that this recipe works also for you."
