sarvant analyzes files from the sysstat utility "sar" and produces
graphs of the collected data using gnuplot. It supports user-defined
data source collection, debugging, start and end times, interval
counting, and output types (Postscript, PDF, and PNG). It's also
capable of using gnuplot's graph smoothing capability to soften spiked
line graphs. It can analyze performance data over both short and long
periods of time.
