Monitoring Infrastructure:
- lib/towerops/monitoring/ping.ex - OS-agnostic ping functionality that works on macOS, Linux, and Windows
- lib/towerops/monitoring/equipment_monitor.ex - GenServer that monitors individual equipment at configurable intervals
- lib/towerops/monitoring/supervisor.ex - DynamicSupervisor with Registry for managing monitor workers
- lib/towerops/monitoring.ex - Context for creating and querying monitoring checks
Database:
- monitoring_checks table stores historical ping results with status, response time, and timestamps
- Indexed on (equipment_id, checked_at) for efficient querying
Real-Time Updates:
- PubSub broadcasting on equipment:#{id} topic when status changes
- Equipment show page subscribes to updates and refreshes automatically
- Manual "Check Now" button to trigger immediate checks
Application Integration:
- Monitoring.Supervisor added to application supervision tree
- All monitored equipment starts monitoring automatically on app startup
- Recent checks displayed in Equipment show page
How It Works
1. On application start, a monitor GenServer is spawned for each equipment with monitoring_enabled: true
2. Each monitor pings its equipment at the configured interval (default 5 minutes)
3. Results are saved to monitoring_checks table
4. Equipment status is updated if it changes (up ↔ down)
5. Status changes are broadcast via PubSub to all connected LiveViews
6. The Equipment show page updates in real-time when status changes
