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
- Sites schema with hierarchical parent-child relationships
- CRUD operations for sites
- Sites context with helper functions
- LiveView pages:
- /orgs/:slug/sites - List all sites
- /orgs/:slug/sites/new - Create new site
- /orgs/:slug/sites/:id - View site details
- /orgs/:slug/sites/:id/edit - Edit site
- Support for site locations and descriptions
- Site tree builder for hierarchy visualization
2. Equipment Management
- Equipment schema with monitoring fields
- IP address validation (IPv4 & IPv6)
- Equipment status tracking (up/down/unknown)
- Customizable check intervals per equipment
- Equipment context with CRUD operations
- LiveView pages:
- /orgs/:slug/equipment - List all equipment
- /orgs/:slug/equipment/new - Add equipment
- /orgs/:slug/equipment/:id - View equipment details
- /orgs/:slug/equipment/:id/edit - Edit equipment
- Equipment can be added from site pages
- Status badges and last checked timestamps
3. Database Schema
- sites table with self-referencing parent_site_id
- equipment table with status tracking
- All migrations run successfully
- Proper indexes on foreign keys and status
4. Features Implemented
- ✅ IP address validation using :inet.parse_address
- ✅ Site hierarchy with parent-child relationships
- ✅ Equipment linked to sites
- ✅ Monitoring enabled/disabled per equipment
- ✅ Customizable check intervals (30s - 3600s)
- ✅ Status tracking (up/down/unknown)
- ✅ Timestamps for last check and last status change
- ✅ Organization-scoped data (users only see their org's data)
