- Fix email notification aggregation to send batched notifications instead of individual emails
- Fix startup data collection to properly process initial status without triggering change notifications
- Maintain event-driven transmission while preserving aggregated notification batching
- Update version from 0.1.19 to 0.1.20 across all components
Major architectural improvements:
CORE CHANGES:
- Remove notification_interval_seconds - status aggregation now immediate
- Status calculation moved to collection phase instead of transmission
- Event-driven transmission triggers immediately on status changes
- Dual transmission strategy: immediate on change + periodic backup
- Real-time notifications without batching delays
TECHNICAL IMPROVEMENTS:
- process_metric() now returns bool indicating status change
- Immediate ZMQ broadcast when status changes detected
- Status aggregation happens during metric collection, not later
- Legacy get_nixos_build_info() method removed (unused)
- All compilation warnings fixed
BEHAVIOR CHANGES:
- Critical alerts sent instantly instead of waiting for intervals
- Dashboard receives real-time status updates
- Notifications triggered immediately on status transitions
- Backup periodic transmission every 1s ensures heartbeat
This provides much more responsive monitoring with instant alerting
while maintaining the reliability of periodic transmission as backup.
- Implement per-collector interval timing respecting NixOS config
- Remove all hardcoded timeout/interval values and make configurable
- Add tmux session requirement check for TUI mode (bypassed for headless)
- Update agent to send config hash in Build field instead of nixos version
- Add nginx check interval, HTTP timeouts, and ZMQ transmission interval configs
- Update NixOS configuration with new configurable values
Breaking changes:
- Build field now shows nix store config hash (8 chars) instead of nixos version
- All intervals now follow individual collector configuration instead of global
New configuration fields:
- systemd.nginx_check_interval_seconds
- systemd.http_timeout_seconds
- systemd.http_connect_timeout_seconds
- zmq.transmission_interval_seconds
- Add cm-rebuild systemd service for process isolation
- Add sudo permissions for service control and journal access
- Remove verbose flag for cleaner output
- Ensures reliable rebuild operations without agent crashes
- Update agent, dashboard, and shared package versions from 0.1.0 to 0.1.11
- Ensures agent version reporting shows correct v0.1.11 instead of v0.1.0
- Synchronize package versions with git tag for consistent version tracking
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
