speedtest-z 0.4.1

Automates major speed test sites with a web browser for continuous network quality monitoring

speedtest-z

日本語版 / Japanese

speedtest-z automates major speed test sites with a web browser, capturing real user-experience network quality for continuous monitoring.

• Supports 8 speed test sites (Cloudflare, Netflix, Ookla, M-Lab, and more)
• Zabbix integration for continuous network quality monitoring
• Quick start: pip install speedtest-z

Features

• Runs speed tests on 8 different sites automatically (Cloudflare, Netflix/fast.com, Google Fiber, Ookla, Box-test, M-Lab, USEN, iNonius)
• Sends results to Zabbix via trapper items (using zappix)
• Configurable test frequency per site (probability-based throttling)
• Screenshot capture for debugging
• Headless or GUI Chrome mode
• CLI with --dry-run, site selection, etc.
• systemd timer integration for scheduled execution

Prerequisites

• Python >= 3.10
• Google Chrome browser (not installable via pip -- must be installed separately)

Installation

pip install speedtest-z

Development Setup

git clone https://github.com/shigechika/speedtest-z.git
cd speedtest-z
python3 -m venv .venv
. .venv/bin/activate
pip install -e .

Dependencies

• selenium -- Browser automation
• zappix -- Zabbix sender protocol

Tab Completion (optional)

pip install speedtest-z[completion]
eval "$(register-python-argcomplete speedtest-z)"

Add the eval line to your shell profile (~/.bashrc or ~/.zshrc) to enable it permanently.

Configuration

config.ini

The configuration file is searched in the following order (-c / --config can override):

1. ./config.ini in the current directory
2. ~/.config/speedtest-z/config.ini (XDG_CONFIG_HOME)

Copy config.ini-sample to one of these locations and edit as needed.

Sections

[general]
# Execution mode
dryrun = true          # true = do not send data to Zabbix
headless = true        # true = run Chrome in headless mode
timeout = 30           # timeout in seconds for each test
# ookla_server = IPA CyberLab   # Ookla test server (omit for auto-select)

[zabbix]
# Zabbix server settings
server = 127.0.0.1
port = 10051
host = speedtest-agent   # Zabbix host name for trapper items

[snapshot]
# Screenshot capture settings
enable = true
save_dir = ./snapshots

[frequency]
# Execution probability per site (0-100)
# 100 = always run, 50 = ~50% chance, 0 = disabled
cloudflare = 100
netflix = 100
google = 100
ookla = 50
boxtest = 50
mlab = 10
usen = 50
inonius = 50

logging.ini

An optional logging.ini file can be used to customize log output. The file is searched in the same order as config.ini:

1. ./logging.ini in the current directory
2. ~/.config/speedtest-z/logging.ini (XDG_CONFIG_HOME)

If neither is found, the default logging configuration (INFO level to stdout) is used.

Usage

speedtest-z [options] [site ...]

Options

Option	Description
-V, --version	Show program version and exit
-c, --config CONFIG	Config file path (default: ./config.ini or ~/.config/speedtest-z/config.ini)
-n, --dry-run	Test run (do not send data to Zabbix)
--headless	Run Chrome in headless mode
--no-headless, --headed	Run Chrome with GUI (non-headless)
--timeout SECONDS	Timeout in seconds for each test
--list-sites	List available test sites and exit
-d, --debug	Enable debug output
site	Positional argument(s): test site(s) to run (default: all)

Examples

# Run all test sites (dry-run)
speedtest-z -n

# Run specific sites
speedtest-z cloudflare netflix

# Run with GUI browser for debugging
speedtest-z --no-headless -d cloudflare

# List available sites
speedtest-z --list-sites

Supported Test Sites

Site	URL	Metrics (Zabbix keys)
cloudflare	https://speed.cloudflare.com/	download, upload, latency, jitter
netflix	https://fast.com/	download, upload, latency, server-locations
google	https://speed.googlefiber.net/	download, upload, ping
ookla	https://www.speedtest.net/	download, upload, ping
boxtest	https://www.box-test.com/	POP, DownloadSpeed, DownloadDuration, DownloadRTT, UploadSpeed, UploadDuration, UploadRTT, latency
mlab	https://speed.measurementlab.net/	download, upload, latency, retrans
usen	https://speedtest.gate02.ne.jp/	download, upload, ping, jitter
inonius	https://inonius.net/speedtest/	IPv4/IPv6: DL, UL, RTT, JIT, MSS

All Zabbix item keys are prefixed with the site name (e.g., cloudflare.download, usen.ping, inonius.IPv4_DL).

Zabbix Integration

1. Import the speedtest-z_templates.yaml template into Zabbix.
2. All items are trapper type -- the agent pushes data to Zabbix using the zappix sender protocol.
3. Set the [zabbix] section in config.ini to match your Zabbix server settings.
4. The host value in config.ini must match the host name registered in Zabbix.

Deployment (systemd)

The deploy/ directory contains systemd unit files for scheduled execution:

File	Description
speedtest-z.service	Service unit (runs speedtest-z from the venv)
speedtest-z.timer	Timer unit (runs every 6 minutes)
SeleniumCleaner.cron	Cron job to clean up stale Chrome temp files

Setup

# Copy unit files
cp deploy/speedtest-z.service ~/.config/systemd/user/
cp deploy/speedtest-z.timer ~/.config/systemd/user/

# Reload and enable
systemctl --user daemon-reload
systemctl --user enable --now speedtest-z.timer

# Check status
systemctl --user status speedtest-z.timer
systemctl --user list-timers

Optionally, install the cron job for cleaning up stale Chrome temporary directories:

sudo cp deploy/SeleniumCleaner.cron /etc/cron.d/SeleniumCleaner

Share Your Results!

Got the fastest or slowest speed test result? We'd love to see it!

Submit your results via GitHub Issues with:
