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

# CM Dashboard Agent Performance Benchmark
|
|
|
|
## Test Environment
|
|
- Host: srv01
|
|
- Rust: release build with optimizations
|
|
- Test date: 2025-10-16
|
|
- Collection interval: 5 seconds (realtime for all collectors)
|
|
|
|
## Benchmark Methodology
|
|
1. Set all collectors to realtime (5s interval)
|
|
2. Test each collector individually
|
|
3. Measure CPU usage with `ps aux` after 10 seconds
|
|
4. Record collection time from debug logs
|
|
|
|
## Baseline - All Collectors Enabled
|
|
|
|
### Results
|
|
- **CPU Usage**: 74.6%
|
|
- **Total Metrics**: ~80 (5 CPU + 6 Memory + 3 Disk + ~66 Systemd)
|
|
- **Collection Time**: ~1350ms (dominated by systemd collector)
|
|
|
|

|
|
- **Metrics Count**: TBD
|
|

|
|
|
|
### Systemd Collector Only
|
|
- **CPU Usage**: TBD%
|
|
- **Metrics Count**: TBD
|
|
