Log network speed to a CSV routinely and display in a Dashboard.

Requires the speedtest-cli Python CLI tool: https://github.com/sivel/speedtest-cli

• Install Python speedtest-cli: pip install speedtest-cli or easy_install speedtest-cli
• Install required Node packages: npm install
• Run the app: node speed.js
• Check speed_test.csv after a few hours
• If you run the webserver visit https://127.0.0.1:3131

Configure the options in the first few lines of the speed.js file.

  root: '/path/to/speed-logger',      // Root path of project
  bin: '/path/to/.local/bin',         // Path to folder where `speedtest-cli` installed

  interval: 300,                      // Interval of test in seconds
  logger: true,                       // Save test results
  loggerFileName: 'speed_test.csv',   // Name of file to save history

  enableWebInterface: true,           // Web interface of result
  webInterfacePort: 3131,             // Port of web interface
  webInterfaceListenIp: "0.0.0.0",    // IP to start server

  enableCLICharts: false,             // Show graph in CLI
  clearCLIBetweenTest: false,         // Clear screen between test
  consoleLog: true,                   // Output logging to console

  secureDomains: null,                // Array of strings [ 'www.example.com' ]
  secureAdminEmail: '[email protected]'  // The admin for the secure email confirmation

You can secure the http connection by creating a Let's Encrypt certificate as outlined below.

# 1) Install Let's Encrypt:
wget https://dl.eff.org/certbot-auto
chmod a+x certbot-auto

# 2) Create dns entry and add _acme-challenge as TXT with key value:
./certbot-auto certonly --agree-tos --renew-by-default --manual --preferred-challenges=dns -d www.example.com

# 3) Copy keys to certs:
cp /etc/letsencrypt/* ./certs/ -r

# 4) To renew key, if required:
./certbot-auto renew

You need to configure the secureDomains and secureAdminEmail once the above has been configured.

If you want to run this and log your results continuously there is a convienent systemd boot script included in the repository called speed-logger.service which can be used on all Debian and Ubuntu OSes and any other OS that supports systemd.

To setup the service:

$ sudoedit /etc/systemd/system/speed-logger.service

Paste the contents of speed-logger.service and be sure to edit the following details:

# Change Environment NODE_VERSION to the version of Node installed on your machine.
Environment=NODE_VERSION=16.10
# Change User to the user who has read/write access to the speed-logger folder.
User=changeme
# Update the ExecStart with the full path to both `node` and where `speed.js` is.
ExecStart=/path/to/node /path/to/speed-logger/speed.js

Save your edited /etc/systemd/system/speed-logger.service file and enable and start the service.

$ sudo systemctl enable speed-logger.service
Created symlink /etc/systemd/system/multi-user.target.wants/speed-logger.service → /etc/systemd/system/speed-logger.service.

$ sudo systemctl start speed-logger.service
