Periodic Internet SpeedTest on Linux

Prerequisites

• Speedtest.net CLI
• cron
• git
• Python 3.6 or later (only to plot results)

Setting Up

1. Set up cron by launching crontab -e.
2. Add the following line:

* * * * * speedtest -f csv >> <out_file>

where <out_file> is the absolute path to out.csv in this repository.

To reset the history of recorded data, run

git checkout out.csv

Plot Results

Create a virtual environment:

python3 -m venv <venv_name>

Activate the virtual environment (source <venv_name>/bin/activate), then install dependencies:

pip3 install numpy plotly

Finally, execute the script to generate the plots:

python3 plot.py

This will produce the files speed.html and latency.html, containing the desired plots.
