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.
- 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
- 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
- Add support for both proxied and static nginx sites
- Proxied sites show 'P' prefix and check backend URLs
- Static sites check external HTTPS URLs
- Fix services panel column alignment for main services
- Keep 10-second timeout for all site checks
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.
Resolves widget data persistence issue where switching hosts left stale data
from the previous host displayed in widgets.
Key improvements:
- Add Clone derives to all widget structs (CpuWidget, MemoryWidget,
ServicesWidget, BackupWidget)
- Create HostWidgets struct to cache widget states per hostname
- Update TuiApp with HashMap<String, HostWidgets> for per-host storage
- Fix borrowing issues by cloning hostname before mutable self borrow
- Implement instant widget state restoration when switching hosts
Tab key host switching now displays cached widget data for each host
without stale information persistence between switches.
- 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
