VISUALIZATION

since httpbench is able to return its results csv-like, it's easy to process the data using gnuplot.

gather data

#!/bin/sh

site=${1:-localhost}

exec > ${site}.csv 2> ${site}.err
while true; do
    httpbench.pl https://${site}/ -n 100 -c 10 -a --csv | grep 'avg$'
    sleep 300
done
