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.

Sarvant .3 was released! Phew!
10-23-2002 Complete re-write in Python. Sarvant is now a python program... It requires the gnuplot-py module, which in turn requires the python Numeric module: The can be found: http://gnuplot-py.sourceforge.net/ and http://sourceforge.net/projects/numpy/ (download and install the latest 'numpy' package) If there are any python programmers that can give me some pointers to make the program look more python-esque, please do so. I'm trying to migrate from Perl to Python. If you are comparing sar files, you don't have to first generate the data sets you want to compare to, sarvant will do it on the fly. Do a sarvant.py --help for details. Added statistics feature-- do a --stats to get stats printed to the graph. No longer using demfiles to communicate with GNUPlot, instead using pipes via the gnuplot-py module. No longer using mpage to concatenate postscript files, using 'cat' instead :) (duh!)
Wow this has been a learning experience. I'm putting the finishing touches on the new totally re-written sarvant (in python now). Just added statistics (min,max,avg) to be printed to the graph if you desire. Next step is to get multiple datasets working, them I'm done.. Look for it to drop in the next couple of days.
First off, I'm re-writing the program in Python. If my first real Python app looks anything like my first Perl app I did a few years ago, please hold back the laughs. It is going to support print statistics about the information gathered to the graphs themselves and possibly making HTML reports. Please hang in tight, release should be out within the next 7 days.
.1-1 Added some example graphs. Removed show-stopping bug in script. .1 initial release
sarvant .1 has been released.
