AI Analysis

●●●BangerSolve My ProblemNiche GemShip It

Replaces Prometheus+Grafana complexity with one container, zero config install.

Strengths
  • •Genuinely minimal footprint: 4 deps, ~50MB memory, single HTML file dashboard—no build step.
  • •Friction-free install with interactive setup and Cloudflare Tunnel baked in, not bolted on.
  • •Six concrete anomaly detection rules with Telegram alerts and sane cooldown logic address real pain.
Weaknesses
  • •SQLite-only metrics storage has no retention policy or export; cluster monitoring impossible.
  • •Anomaly thresholds hardcoded; no custom rules, alerting templates, or multi-channel option beyond Telegram.
Target Audience

Self-hosted Docker operators, homelab runners, small teams managing few containers

Post Description

I built this because existing monitoring solutions (Prometheus+Grafana, Portainer) felt like overkill for simply watching a few Docker containers.

DockWatch is a single container that provides: - Real-time dashboard (CPU, memory, network, disk, temperature) - 6 anomaly detection rules with Telegram alerts - Self-signed HTTPS or Cloudflare Tunnel for remote access - Single HTML file dashboard — no build step

Stack: FastAPI, aiodocker, Chart.js, SQLite. 4 Python dependencies total. ~50MB memory.

Design philosophy: do one thing well. Monitor containers, detect anomalies, send alerts. No container management, no custom metrics, no query language.

Install: git clone https://github.com/deep-on/dockwatch.git && bash install.sh

I'd love feedback on the architecture and what features would make this more useful. The anomaly detection rules in particular — are the default thresholds reasonable?

Website Monitoring with Telegram Alerts

Telegram-first alerting is the product's personality — there are website/API/cron/SSL checks and an explicit "Start without email" flow that keeps signup friction low. The retro terminal UI is tasteful and suggests an MVP you can click through fast, but it doesn't yet offer a clear feature advantage over established uptime tools unless Telegram-only delivery is your hard requirement.

Tori Terminal-native Docker monitoring with alerting in a single binary

The trick here is practical: an agent exposes a Unix socket on the host and the client connects over SSH, so you get monitoring and alerts without opening ports. It bundles container log tailing (Docker log API), alert evaluation, and SQLite storage into a tiny Go binary — neat for small fleets, but the README warns it's still early-stage so expect rough edges.
