Sar2gp converts files generated by 'Sar' from Sysstat into Gnuplot format, and then generates the graphic. User can select which values wants to be plotted. Sar2gpGUI is a graphical user interface that can deal with all Sar2gp options.
sarface is a user-interface to the sysstat/sar database which inputs data from sar and plots to a live X11 graph via gnuplot. It mimics the cmd-line options from sar but can cross-plot any two or more stats and apply simple mathematical functions them.
Command line tool that creates charts from SysStat output and presents them through HTML pages. It is also capable to display charts from several machines at a single site.
Sarvant (SAR Visual ANalysis Tool) is a python script that will analyze a sar file (from the sysstat utility, 'sar') and produce graphs using gnuplot of the collected data.
The Linux Proc filesystem reflects different statistics of a running Linux desktop/server. Most of the tools today like mpstat, pidstat etc from sysstat package use the information form Linux proc file system to provide the statistics related to hardware resources like CPU, memory, disk and Network. This project tried to provide a web based visulaization of all the parameters which are exposed in Proc filesystem. It also provide the storage of this statistical data in real time databases like RRD tool for further online/online analysis.
