Fully restored CM Dashboard as a complete monitoring system with working
status evaluation and email notifications.
COMPLETED PHASES:
✅ Phase 1: Fixed storage display issues
- Use lsblk instead of findmnt (eliminates /nix/store bind mount)
- Fixed NVMe SMART parsing (Temperature: and Percentage Used:)
- Added sudo to smartctl for permissions
- Consistent filesystem and tmpfs sorting
✅ Phase 2a: Fixed missing NixOS build information
- Added build_version field to AgentData
- NixOS collector now populates build info
- Dashboard shows actual build instead of "unknown"
✅ Phase 2b: Restored status evaluation system
- Added status fields to all structured data types
- CPU: load and temperature status evaluation
- Memory: usage status evaluation
- Storage: temperature, health, and filesystem usage status
- All collectors now use their threshold configurations
✅ Phase 3: Restored notification system
- Status change detection between collection cycles
- Email alerts on status degradation (OK→Warning/Critical)
- Detailed notification content with metric values
- Full NotificationManager integration
CORE FUNCTIONALITY RESTORED:
- Real-time monitoring with proper status evaluation
- Email notifications on threshold violations
- Correct storage display (nvme0n1 T: 28°C W: 1%)
- Complete status-aware infrastructure monitoring
- Dashboard is now a monitoring system, not just data viewer
The CM Dashboard monitoring system is fully operational.
Replace fragile string-based metrics with type-safe JSON data structures.
Agent converts all metrics to structured data, dashboard processes typed fields.
Changes:
- Add AgentData struct with CPU, memory, storage, services, backup fields
- Replace string parsing with direct field access throughout system
- Maintain UI compatibility via temporary metric bridge conversion
- Fix NVMe temperature display and eliminate string parsing bugs
- Update protocol to support structured data transmission over ZMQ
- Comprehensive metric type coverage: CPU, memory, storage, services, backup
Version bump to 0.1.131
