📊 Add System Health Monitoring & API Checks

[adrianwedd]

Objective

Implement comprehensive health monitoring for all system components with graceful degradation when services unavailable.

Components to Monitor

• Google APIs: Calendar, Fitness quota and rate limits
• Claude Session: Browser automation health and session expiry
• Music System: Jellyfin connection and Chromecast availability
• Nest Devices: Device discovery and broadcast capability
• Redis: State storage and session management

Health Check Endpoints

• /health/google - API status and quota remaining
• /health/claude - Session validity and browser status
• /health/music - Jellyfin and Chromecast connectivity
• /health/devices - Nest device availability
• /health/detailed - Comprehensive system status

Graceful Degradation

• Continue core functionality when non-critical services down
• Clear user messaging about reduced capabilities
• Automatic service recovery attempts
• Fallback modes for each component

Priority: Medium

Important for production stability and user experience

📊 System health monitoring partially implemented:

Already Working:

• /health endpoint showing component status
• Test validation suite created
• Database monitoring active
• Redis connection checks
• Google API status tracking

Today's Validation Results:

• 60% of tests passing
• All critical components operational
• Full data utilization active

See test_system_validation.py for comprehensive health checks.

✅ Health Monitoring Partially Implemented

Current Health Endpoints:

• ✅ - Basic system health check working
• ✅ Music system status via
• ✅ Google API integration health (calendar/fitness)
• ✅ Nest device discovery and connectivity
• ⚠️ Claude session health needs dedicated endpoint

Working Health Checks:

1. Music System:

   • Jellyfin service status ✅
   • Chromecast connectivity ✅ (4 devices found)
   • External access via Cloudflare tunnel ✅

2. Google APIs:

   • Calendar integration working ✅
   • Fitness data retrieval active ✅
   • Token refresh functioning ✅

3. Nest Devices:

   • 3 devices discovered and connected ✅
   • Nudge system operational ✅

Recent Infrastructure Additions:

• Cloudflare Tunnel: Auto-restart systemd service
• Jellyfin Service: Running and monitored
• Music Integration: Full health status available

Still Needed:

• - Browser automation session validity
• - Comprehensive component status
• Graceful degradation messaging
• Automatic recovery orchestration

Status: Core health monitoring infrastructure in place, needs dedicated health dashboard.
