- Update BackupData structure to support multiple backup disks
- Scan /var/lib/backup/status/ directory for all status files
- Calculate status icons for backup and disk usage
- Aggregate repository status from all disks
- Update dashboard to display all backup disks with per-disk status
- Display repository list with count and aggregated status
Replace timestamp parsing with direct display of start_time from backup TOML file to ensure timestamp always appears regardless of format. Remove empty line spacing above backup section for compact layout.
Changes:
- Remove parsed timestamp fields and use raw start_time string from TOML
- Display backup time directly from TOML file without parsing
- Remove blank line above backup section for tighter layout
- Simplify BackupData structure by removing last_run and next_scheduled fields
Version bump to v0.1.150
Replace standalone backup widget with compact backup section in system widget displaying disk serial, temperature, wear level, timing, and usage information.
Changes:
- Remove standalone backup widget and integrate into system widget
- Update backup collector to read TOML format from backup script
- Add BackupDiskData structure with serial, usage, temperature, wear fields
- Implement compact backup display matching specification format
- Add time formatting utilities for backup timing display
- Update backup data extraction from TOML with disk space parsing
Version bump to v0.1.149
Implements clean structured data collection eliminating all string metric
parsing bugs. Collectors now populate AgentData directly with type-safe
field access.
Key improvements:
- Mount points preserved correctly (/ and /boot instead of root/boot)
- Tmpfs discovery added to memory collector
- Temperature data flows as typed f32 fields
- Zero string parsing overhead
- Complete removal of MetricCollectionManager bridge
- Direct ZMQ transmission of structured JSON
All functionality maintained: service tracking, notifications, status
evaluation, and multi-host monitoring.
- Add disk wear percentage collection from SMART data in backup script
- Add backup_disk_wear_percent metric to backup collector with thresholds
- Display wear percentage in backup widget disk section
- Fix storage section overflow handling to use consistent "X more below" logic
- Update maintenance mode to return pending status instead of unknown
- Add new Status::Inactive variant to enum for better service state representation
- Agent now assigns Status::Inactive instead of Status::Warning for inactive services
- Dashboard displays inactive services with empty circle (○) icon in gray color
- User-stopped services still show as Status::Ok with green filled circle
- Inactive services treated as OK for host status aggregation
- Improves visual clarity between active (●), inactive (○), and warning (◐) states
- Add Status::Offline enum variant for disconnected hosts
- All configured hosts now always visible showing offline status when disconnected
- Add WakeOnLAN support using wake-on-lan Rust crate
- Implement w key binding to wake offline hosts with MAC addresses
- Simplify configuration to single [hosts] section with MAC addresses only
- Change critical status icon from ◯ to ! for better visibility
- Add proper MAC address parsing and error handling
- Silent WakeOnLAN operation with logging for success/failure
Configuration format:
[hosts]
hostname = { mac_address = "AA:BB:CC:DD:EE:FF" }
- Add sudo permissions for systemctl and nixos-rebuild commands
- Use sudo in agent command execution for proper privileges
- Fix backup collector to handle missing status files gracefully
- Eliminate backup error spam when no backup system is configured
Add comprehensive hysteresis support to prevent status oscillation near
threshold boundaries while maintaining responsive alerting.
Key Features:
- HysteresisThresholds with configurable upper/lower limits
- StatusTracker for per-metric status history
- Default gaps: CPU load 10%, memory 5%, disk temp 5°C
Updated Components:
- CPU load collector (5-minute average with hysteresis)
- Memory usage collector (percentage-based thresholds)
- Disk temperature collector (SMART data monitoring)
- All collectors updated to support StatusTracker interface
Cache Interval Adjustments:
- Service status: 60s → 10s (faster response)
- Disk usage: 300s → 60s (more frequent checks)
- Backup status: 900s → 60s (quicker updates)
- SMART data: moved to 600s tier (10 minutes)
Architecture:
- Individual metric status calculation in collectors
- Centralized StatusTracker in MetricCollectionManager
- Status aggregation preserved in dashboard widgets
- Add BackupCollector for reading TOML status files with disk space metrics
- Implement BackupWidget with disk usage display and service status details
- Fix backup script disk space parsing by adding missing capture_output=True
- Update backup widget to show actual disk usage instead of repository size
- Fix timestamp parsing to use backup completion time instead of start time
- Resolve timezone issues by using UTC timestamps in backup script
- Add disk identification metrics (product name, serial number) to backup status
- Enhance UI layout with proper backup monitoring integration
This commit addresses several key issues identified during development:
Major Changes:
- Replace hardcoded top CPU/RAM process display with real system data
- Add intelligent process monitoring to CpuCollector using ps command
- Fix disk metrics permission issues in systemd collector
- Optimize service collection to focus on status, memory, and disk only
- Update dashboard widgets to display live process information
Process Monitoring Implementation:
- Added collect_top_cpu_process() and collect_top_ram_process() methods
- Implemented ps-based monitoring with accurate CPU percentages
- Added filtering to prevent self-monitoring artifacts (ps commands)
- Enhanced error handling and validation for process data
- Dashboard now shows realistic values like "claude (PID 2974) 11.0%"
Service Collection Optimization:
- Removed CPU monitoring from systemd collector for efficiency
- Enhanced service directory permission error logging
- Simplified services widget to show essential metrics only
- Fixed service-to-directory mapping accuracy
UI and Dashboard Improvements:
- Reorganized dashboard layout with btop-inspired multi-panel design
- Updated system panel to include real top CPU/RAM process display
- Enhanced widget formatting and data presentation
- Removed placeholder/hardcoded data throughout the interface
Technical Details:
- Updated agent/src/collectors/cpu.rs with process monitoring
- Modified dashboard/src/ui/mod.rs for real-time process display
- Enhanced systemd collector error handling and disk metrics
- Updated CLAUDE.md documentation with implementation details
- Fix systemctl, du, df, uptime, ss, journalctl commands
- Add sudo for du command (needed for directory access)
- This should resolve all remaining command path issues in the service
- Storage, backup, and system monitoring should now work properly
Replaced system-wide disk usage with accurate per-service tracking by scanning
service-specific directories. Services like sshd now correctly show minimal
disk usage instead of misleading system totals.
- Rename storage widget and add drive capacity/usage columns
- Move host display to main dashboard title for cleaner layout
- Replace separate alert displays with color-coded row highlighting
- Add per-service disk usage collection using du command
- Update services widget formatting to handle small disk values
- Restructure into workspace with dedicated agent and dashboard packages
