- Move Status::Inactive to lowest priority in enum (before Ok)
- Status aggregation now prefers Ok over Inactive in mixed scenarios
- Title bar stays green when mixing active and inactive services
- Inactive services still show gray icons but don't affect overall status
- Ensures healthy systems with stopped services maintain green status
- 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" }
- Change system panel title from 'NixOS:' to 'NixOS hostname:'
- Make main dashboard title 'cm-dashboard' bold in top bar
- Remove unused Typography::title() function to fix warnings
- Update SystemWidget::render_with_scroll to accept hostname parameter
- Update version to 0.1.41 in all Cargo.toml files and dashboard code
Major UI simplification and navigation improvements:
Changes:
- Removed panel selection concept entirely (no more Shift+Tab)
- Service selection always visible with blue highlighting
- Up/Down arrows now directly control service selection
- Added j/k vi-style navigation keys as alternatives to arrow keys
- Removed panel focus borders - all panels look uniform
- Service commands (s/S) work without panel focus requirements
- Updated keyboard shortcuts to reflect simplified navigation
Navigation:
- Tab: Switch hosts
- ↑↓/jk: Select service (always works)
- R: Rebuild host
- s: Start service
- S: Stop service
- q: Quit
The interface is now much simpler and more intuitive with direct service control.
- Add Typography::tree() style using blue Theme::highlight() color
- Update system, backup, and services widgets to use consistent blue tree styling
- Centralizes tree color management in theme module for easy maintenance
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
Removed unused widget subscription system, cache utilities, error variants,
theme functions, and struct fields. Replaced subscription-based widgets
with direct metric filtering. Build now completes with zero warnings.
- 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
