Infra Watchdog — Infrastructure Monitoring & Health Alerts

Infra Watchdog — Infrastructure Monitoring & Health Alerts

Self-hosted infrastructure monitoring for OpenClaw agents. Zero external SaaS required — monitors everything locally and alerts via WhatsApp, Telegram, or Discord.

What It Does

• HTTP/HTTPS endpoint monitoring — checks status codes, response time, SSL validity
• TCP port checks — database, SSH, custom services
• Docker container status — running, stopped, unhealthy
• System resources — CPU, RAM, disk usage with configurable thresholds
• SSL certificate expiry — alerts 30 days before expiry
• DNS resolution checks — verifies domain → IP mappings
• Proxmox VM/CT status — checks via local API
• Alerts via WhatsApp/Telegram/Discord — with configurable cooldown

Quick Start

# Initialize data directory & config
infra-watchdog init

# Add your first monitor
infra-watchdog add-monitor --type http --name "My API" --url https://myapi.example.com

# Add a TCP port check
infra-watchdog add-monitor --type tcp --name "PostgreSQL" --host localhost --port 5432

# Add a Docker container check
infra-watchdog add-monitor --type docker --name "My App" --container myapp

# Run all checks now
infra-watchdog check

# View current status dashboard
infra-watchdog dashboard

# Install auto-check cron (every 5 min)
infra-watchdog cron-install

Alert Channels

Use Cases

Homelab Monitoring

Track all your self-hosted services: Proxmox, Docker stacks, databases, Jellyfin, Home Assistant, etc. Get a WhatsApp alert the moment anything goes down.

API Uptime Monitoring

If you sell API services on RapidAPI, this skill monitors your endpoints 24/7 and pings you before customers notice an outage.

SSL Expiry Prevention

Never let a certificate expire again. Get a WhatsApp warning 30 days before expiry.

Resource Alerts

Disk full at 3am? Get alerted before it kills your services.

Data Storage

All data stored locally at ~/.openclaw/workspace/infra-watchdog-data/. SQLite database, no cloud sync, no telemetry.

Requirements

• Python 3.8+
• Docker (optional, for container monitoring)
• OpenClaw 1.0+
