Facts

Purpose: bwmon monitors bandwidth on a single Linux host, with live RX/TX, per-process attribution, spike forensics, and six months of history.github.com · 3 Oct 2026
Live monitoring: The live panel polls RX/TX every second and shows a rolling chart and top processes.github.com · 3 Oct 2026
Spike forensics: When interface traffic exceeds five times its rolling two-minute average, bwmon records process attribution, all-interface rates, and top conntrack flows.github.com · 3 Oct 2026
History: bwmon stores five-minute samples for six months and offers views from one hour through all time, with adaptive bucketing.github.com · 3 Oct 2026
Alerts: A banner appears when the rolling five-minute average reaches 40 Mbps, and cleared alerts remain in the history table.github.com · 3 Oct 2026
Install: The project describes a one-command install using sudo ./setup.sh and opens its dashboard at the host on port 8080 by default.github.com · 3 Oct 2026
Requirements: It requires a Linux host with kernel 4.0 or later and root access; the installer uses apt, while other distributions require manual dependency installation.github.com · 3 Oct 2026
Interface limit: The project describes monitoring one network interface, auto-detected from the default route unless overridden.github.com · 3 Oct 2026
Resource use: The README says six months of history uses at most 50 MB per interface and the bwprocs daemon uses less than one percent of a CPU core at idle.github.com · 3 Oct 2026
Security: The bundled nginx server block is open; the README recommends putting internet-exposed installs behind an authenticated reverse proxy or adding basic authentication.github.com · 3 Oct 2026
License: The project is licensed under MIT.github.com · 3 Oct 2026
Intended use: The README presents bwmon for investigating bandwidth use on a single host and says multi-host or long-horizon analytics call for heavier tools.github.com · 3 Oct 2026
Process attribution: A daemonized nethogs process writes top talkers to a JSON file about every two seconds for the web UI to read.github.com · 3 Oct 2026
History and analytics: It retains five-minute samples for six months and provides 1h, 24h, 7d, 30d, 6m, and all-time views, plus a time-of-week heatmap and rate histogram.github.com · 3 Oct 2026
Integrations and dependencies: The installer can install nethogs, php-fpm, php-cli, and nginx; runtime JavaScript uses a vendored Plotly Basic build.github.com · 3 Oct 2026
Installation: Installation uses a one-command shell script that sets up the collector, systemd service, cron jobs, and nginx server block.github.com · 3 Oct 2026
Requirements and limits: bwmon requires Linux kernel 4.0 or later, root access, and one network interface to monitor; six months of history uses at most 50 MB per interface.github.com · 3 Oct 2026
Distribution support: The installer uses apt for Debian and Ubuntu, while other distributions require manually installing nginx, PHP-FPM, PHP CLI, and nethogs.github.com · 3 Oct 2026
Privacy and hosting: The project describes itself as self-hosted, with no agents, cloud service, or signup required.github.com · 3 Oct 2026
