Generate gnuplot PNG graphics from a dstat CSV file. This is quite dirty but efficient so far. I've been looking around for such utility, found a lot, but not really what I wanted.
To use it, first get a dstat CSV file. For example, with the command:
dstat -t -a --socket -p -C 0,1,2,3,total --aio --top-cpu --top-mem --output dstat.csv --noupdate --nocolor 5 &>/dev/null
Then, plot graphics with the command:
gnuplot-dstat -i dstat.csv -o /tmp/report
