Are you flying blind with your Docker containers? One command changes that.
I built DockWatch — a lightweight, self-hosted Docker monitoring dashboard that gives you full visibility into your containers with zero configuration.
What is DockWatch?
DockWatch runs as a single Docker container and collects real-time CPU, memory, network, and disk metrics from all your containers and the host machine. Everything is displayed in a clean, dark-themed web UI that auto-refreshes every 10 seconds.
No agents to install. No external database. No complex setup. Just mount the Docker socket, run one command, and you're done.
Key Features
- 📊 Real-time Dashboard — Dark-themed UI with sortable tables and Chart.js charts
- 🔍 Container Monitoring — CPU %, memory %, network I/O, block I/O, restart count
- 🌡️ Host Monitoring — CPU/GPU temperature, disk usage, load average
- 🚨 Anomaly Detection — 6 built-in rules: CPU spike, memory overflow, high temp, disk full, unexpected restart, network surge
- 📱 Telegram Alerts — Instant notifications with 30-minute cooldown per alert type
- 🔒 Security — Basic Auth, rate limiting, HTTPS (self-signed or Cloudflare Tunnel)
- ⚡ Lightweight — Only 4 Python packages, SQLite with 7-day retention
Quick Start
git clone https://github.com/deep-on/dockwatch.git && cd dockwatch && bash install.sh
That's it. The interactive installer sets up authentication, Telegram alerts, and HTTPS in under a minute.
Requirements: Docker (with Compose v2), Git, OpenSSL
Anomaly Detection
DockWatch watches your containers 24/7 and alerts you before users notice:
| Rule | Condition |
|---|---|
| Container CPU | >80% for 3 consecutive checks |
| Container Memory | >90% of limit |
| Host CPU Temp | >85°C |
| Host Disk | >90% usage |
| Container Restart | restart_count increased |
| Network Spike | RX 10x surge + >100MB |
All thresholds are configurable via environment variables.
Access Modes
Local Network — Self-signed SSL, access viahttps://localhost:9090
Remote Access — Port forwarding option
Cloudflare Tunnel — Recommended for remote access, no port-forwarding needed, proper TLS certificate
Why I Built This
Existing Docker monitoring solutions are either too heavy (Prometheus + Grafana stack) or too simple (just showing container status). I wanted something in between — lightweight enough to run on a home server, but smart enough to catch problems automatically and ping me on Telegram.
DockWatch is the result: 4 Python dependencies, a single HTML file for the UI, and SQLite for storage. It stays out of your way until something goes wrong.
