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

License

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
