Self-Hosted Monitoring & Uptime

Lighter-weight than the full Prometheus stack. Single-container, beautiful UI, just enough for a homelab or small team.

Server / system monitoring (CPU / RAM / disk / containers)

★ Beszel — lightweight server-monitoring hub with historical data, alerts, Docker container stats, web UI. The newcomer that actually deserves the hype. Single small container. Default for homelabs in 2026.

★ Netdata — per-second metrics, beautiful auto-discovery UI; agent-based. Free; cloud option for fleet view.
- https://github.com/netdata/netdata
Glances — Python; CLI + web mode; quick to set up.
- https://github.com/nicolargo/glances
Cockpit — Red Hat; web admin UI bundled with most distros.

Scrutiny — disk SMART monitor with WebUI.

★ Uptime Kuma — the homelab default; HTTP / TCP / DNS / Ping / DB / push checks; status pages; many notification channels.
- https://github.com/louislam/uptime-kuma
★ Gatus — YAML-configured uptime + status page; great for IaC-driven setups; conditions language is powerful.
- https://github.com/TwiN/gatus
Healthchecks — dead-man's-switch / cron monitor (also covered in Status Pages).
- https://github.com/healthchecks/healthchecks
OpenStatus — open-source status page + monitoring; modern.

Grafana + Beszel + Uptime Kuma datasources — assemble your own dashboard.

Slack / Discord / Telegram / Mattermost / Rocket.Chat / Matrix.
Apprise (@caronc/apprise) — universal notifications adapter; many tools wrap this.
- https://github.com/caronc/apprise
ntfy — push notifications via simple HTTP; pair with iOS / Android app.
- https://github.com/binwiederhier/ntfy
Gotify — alternative push server.

Beszel for system metrics across all your boxes (one hub + an agent per host).
Uptime Kuma for "is this URL up?" + status page for friends/family.
Healthchecks for cron job monitoring (backups, scheduled tasks).
ntfy for phone push when something fires.
All behind Tailscale + Cloudflare Tunnel for remote access.

★ One hub, agents on each box. Beszel works exactly like this; Netdata Cloud does too.
Group dashboards by purpose — "Media servers," "Production," "Storage."
Notification routing — page-worthy alerts to phone push; informational to chat.
Monthly review — silence stale alerts; tune thresholds.
Don't double-alert on the same condition from multiple tools.
