- Add nixos_config_api_key_file option to NixOS configuration
- Support reading API token from file for private repositories
- Automatically inject token into HTTPS URLs (https://token@host/repo.git)
- Graceful fallback to original URL if key file missing/empty
- Default key file location: /var/lib/cm-dashboard/git-api-key
Usage: echo 'your-api-token' | sudo tee /var/lib/cm-dashboard/git-api-key
Replace generic hourglass with specific arrows:
- ↑ (up) for starting services
- ↓ (down) for stopping services
- ↻ (circular) for restarting services
Provides immediate visual feedback for service operations.
Replace direct directory access with git clone/pull approach:
- Add git configuration options (url, branch, working_dir) to NixOS module
- Update SystemConfig and AgentCommand to use git parameters
- Implement ensure_git_repository() method for clone/pull operations
- Agent clones nixosbox to /var/lib/cm-dashboard/nixos-config
- Maintains security while solving permission denied issues
The agent now manages its own copy of the configuration without
needing access to /home/cm directory.
- Change Space key toggle to 's' for start and 'S' for stop
- Remove problematic service status detection logic
- Update statusbar shortcuts to show S/Shift+S instead of Space
- Split UiCommand::ServiceStartStop into ServiceStart and ServiceStop
- Simplify command handling with explicit actions
This resolves the toggle bug where Space always sent start commands
regardless of current service status.
- Implement proper service status checking for start/stop toggle
- Space key now checks current service status and toggles appropriately
- Active services get stopped, inactive services get started
- Fix nixos-rebuild sudo permissions (remove invalid package reference)
- Use only /run/current-system/sw/bin/nixos-rebuild path
- 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
This implements the core functionality for executing remote commands through
the dashboard and providing real-time visual feedback to users.
Key Features:
- Remote service control (start/stop/restart) via existing keyboard shortcuts
- System rebuild command with maintenance mode integration
- Real-time visual feedback with service status transitions
- ZMQ command protocol extension for service and system operations
Implementation Details:
- Extended AgentCommand enum with ServiceControl and SystemRebuild variants
- Added agent-side handlers for systemctl and nixos-rebuild execution
- Implemented command status tracking system for visual feedback
- Enhanced services widget to show progress states (⏳ restarting)
- Integrated command execution with existing keyboard navigation
Keyboard Controls:
- Services Panel: Space (start/stop), R (restart)
- System Panel: R (nixos-rebuild switch)
- Backup Panel: B (trigger backup)
Technical Architecture:
- Command flow: UI → Dashboard → ZMQ → Agent → systemctl/nixos-rebuild
- Status tracking: InProgress/Success/Failed states with visual indicators
- Maintenance mode: Automatic /tmp/cm-maintenance file management
- Service feedback: Icon transitions (● → ⏳ → ● with status text)
- Mark keyboard navigation and service management as completed
- Document all implemented navigation controls and features
- Update current status to reflect working build display
- Replace old future priorities with actual service management tasks
- Add focus-aware selection and visual feedback documentation
Status Icon Color Preservation:
- Preserve original status icon colors (green ● for active, red ● for failed)
- Apply selection highlighting only to service text, not status icons
- Maintain visual health indicators while showing selection state
Focus-Aware Selection Display:
- Only show selection highlighting when Services panel is focused
- Hide selection bar when user switches to System or Backup panels
- Provides clean UI when not actively managing services
Selection Visual Behavior:
- Status icon: Original color (green/red/yellow) with blue background
- Service text: Blue background with black text for clear selection indication
- Unfocused state: All services display normally without selection artifacts
This creates optimal UX where status health information is always visible
and selection highlighting only appears when relevant for user interaction.
Selection Behavior Improvements:
- Limit selection to parent services only (docker, nginx, postgresql, etc.)
- Skip sub-services in navigation (no longer select nginx sub-sites)
- Up/Down arrows now move between actionable services only
Visual Enhancement:
- Preserve original status colors in selection highlighting
- Selected services show blue background with status foreground colors
- Green text for active services, red for failed, even when selected
- Maintains visual health status information during selection
Selection Logic:
- Add parent service index mapping for accurate selection tracking
- Only count parent services in total service count
- Calculate proper parent service index from display line position
- Ensure selection highlights only apply to parent services
This creates a cleaner UX where users only select services they can
actually control (start/stop/restart) while maintaining visual health
status indicators through preserved status colors.
Visual Highlighting Fixes:
- Apply selection highlighting to individual text spans instead of entire paragraph
- Eliminates highlighting of empty space below services on single-service hosts
- Selection now only highlights actual service text content
Selection Logic Improvements:
- Add proper bounds checking in select_next() to prevent invalid selections
- Automatically clamp selection index when services are updated
- Add debug logging to track selection state and movement
Bounds Safety:
- Ensure selection index stays valid when service lists change
- Prevent out-of-bounds access during service updates
- Reset selection to last valid index when services are removed
This fixes the issues where:
1. Single service hosts showed empty space highlighting
2. Multi-service hosts had no visible selection cursor
3. Selection could become invalid when services changed
Service Selection Features:
- Add selection cursor for Services panel with visual highlighting
- Up/Down arrows move service selection instead of scrolling
- Track selected service for future action implementation
- Selection state maintained per host
Panel Navigation Improvements:
- Fix panel switching to only cycle through visible panels
- Dynamic panel list based on backup data availability
- Smart recovery when focused panel becomes invisible
- No more navigation to hidden backup panel
Backup Panel Scrolling Fix:
- Fix backup panel scroll to show actual repository content
- Replace static overflow indicator with proper scroll behavior
- Add scroll position indicators (above/below)
- Show all repositories when scrolling instead of truncated list
Navigation now works correctly with actual UI layout and
provides proper service selection for future action implementation.
- Remove Network panel from navigation cycle
- Fix system panel scrolling to work in both directions
- Add complete scroll support to Services and Backup panels
- Update panel cycling to System → Services → Backup only
- Enhance scroll indicators with proper bounds checking
- Clean up unused Network panel code and references
Resolves issues with non-functional up/down scrolling and
mystery network panel appearing during navigation.
The new keybindings (Shift+Tab, Up, Down, BackTab) weren't working because
the main app.rs event loop was only passing specific keys to the TUI app.
Added handling for:
- KeyCode::BackTab (Shift+Tab panel switching)
- KeyCode::Up (scroll up in focused panel)
- KeyCode::Down (scroll down in focused panel)
Now all keyboard navigation features work correctly.
- Add Typography::tree() style using blue Theme::highlight() color
- Update system, backup, and services widgets to use consistent blue tree styling

Implement agent version tracking to diagnose deployment issues:
- Add get_agent_hash() method to extract Nix store hash from executable path
- Collect system_agent_hash metric in NixOS collector
- Display "Agent Hash" in system panel under NixOS section
- Update metric filtering to include agent hash
This helps identify which version of the agent is actually running
when troubleshooting deployment or metric collection issues.
Update metric filtering to use exact metric names instead of prefix matching.
This resolves the issue where build version showed 'unknown' despite agent
correctly collecting the metric.
- Strip codename part (e.g., '(Warbler)') from nixos-version output
- Display clean version format: '25.05.20251004.3bcc93c'
- Simplify parsing to use raw nixos-version output as requested
- Change from showing version to build format: 'hash dd/mm/yy H:M:S'

- Fix borrow checker errors with clone() for status cache
Add detailed debug logging to track:
- Service discovery start
- Individual service parsing
- Final service count and list
- Empty results indication
This will help identify why cmbox disappeared from dashboard.
Major performance optimization:
- Parse and cache service status during discovery from systemctl list-units
- Eliminate per-service systemctl is-active and show calls
- Reduce systemctl calls from 1+2N to just 1 call total
- For 10 services: 21 calls → 1 call (95% reduction)
- Add fallback to systemctl for cache misses
This completes the major systemctl call reduction goal from TODO.md.
Implement glob pattern matching for service filters:
- nginx* matches nginx, nginx-config-reload, etc.
- *backup matches any service ending with 'backup'
- docker*prune matches docker-weekly-prune, etc.
- Exact matches still work as before (backward compatible)
Addresses TODO.md requirement for '*' filtering support.
Reduce from 2 systemctl commands to 1 by using only:
systemctl list-units --type=service --all
This captures all services (active, inactive, failed) in one call,
eliminating the redundant list-unit-files command.
Achieves the TODO.md goal of reducing systemctl calls.
Remove all sudo -u systemctl commands and user service processing.
Now only collects system services via systemctl list-units/list-unit-files.
Eliminates user service discovery completely as planned in TODO.md.
Change service matching logic from contains-based to exact equality.
Services now match only if service_name == pattern exactly.
This is the first step in the systemd collector optimization plan.
- Fix duplicate storage pool issue by clearing cache on agent startup
- Change storage pool header text to normal color for better readability
- Improve services panel tree icons with proper └─ symbols for last items
- Ensure fresh metrics data on each agent restart
