sar-static-dashboard

Small static web dashboard for Linux server load history using sysstat/sar.

It runs sadf against existing sar logs, renders HTML with inline SVG charts, and exits. There is no database, no resident collector process, no JavaScript dependency, and no third-party Python package dependency.

Requirements

• Linux hosts with sysstat enabled.
• sar and sadf available on each host.
• SSH access from the dashboard host to remote hosts, if remote hosts are used.
• Python 3.10 or newer on the dashboard host.

Quick Start

install -d /etc/sar-static-dashboard /var/www/sysstat-dashboard
cp config.example.json /etc/sar-static-dashboard/config.json
vi /etc/sar-static-dashboard/config.json
./bin/sar_static_dashboard.py \
  --config /etc/sar-static-dashboard/config.json \
  --output /var/www/sysstat-dashboard

Serve /var/www/sysstat-dashboard with nginx, Apache, Caddy, or any static file server. For periodic updates, run the generator from cron or a systemd timer.

Metrics

The default dashboard includes CPU, load, memory, swap, disk, and network charts. Virtual interfaces such as lo, docker*, br-*, and veth* are excluded from the network aggregate.

Security

The dashboard is static, but it can expose operational details. Put it behind HTTP authentication, a VPN, or an IP allowlist unless the data is intentionally public.
