Raspberry PI Speedtester

This repo setup a Raspberry PI to

• periodically (default 10 minutes) make an internet speedtest and store the results locally as json
• act as an iPerf3 Server to be used for testing the LAN speed (the setup is interactive: Select "Yes" when iperf ask if it should install a daemon)

Setup

1. Transfer the content of this repository to the Raspberry Pi
2. Run setup-speedtest-tools.sh to setup the necessary speedtest tools including the cron job

Operation

Speedtester

To run the speedtest, the device must just be powered on and connected via a cable to the network. The speedtest runs by default every 10 minutes and makes one internet speedtest. Each result is stored as separate file in the default locatoin under /opt/speedtest-results.

To evaluate the results, the script /opt/results-to-csv.sh can be called. It extracts some fields of every result and puts them into one big CSV file under /opt/all_results.csv.

To transfer the CSV, just run:

scp pi@speedtestpi:/opt/all_results.csv .

iperf3

To trigger iperf3 on client side, run this command:

iperf3 -c [SERVER_IP]

Results

Periodic Speedtest results

The default location /opt/speedtest-results will look like this after having the device connected for some hours or days:

pi@speedtestpi:/opt/speedtest-results $ ls
