Enhanced telemetry system with comprehensive privacy controls and debugging capabilities: **New Features:** - JSON preview mode (-j/--json-preview): Display telemetry payload without sending - Shows exact JSON structure sent to API for transparency - Saves preview to ~/.config/pecu/telemetry-preview.json - Opens in pager (less/more) for easy review and text selection - Support mode (-s/--support-info): Generate support token for troubleshooting - Automatically enables telemetry and displays Instance ID - Shows formatted support token (PECU-XXXX-XXXX-XXXX format) - Includes system summary (version, channel, profile, Proxmox detection) - Handles both success and failure scenarios with retry instructions **Enhanced Telemetry Metrics:** - Proxmox subscription mode detection (enterprise/no-subscription/test) - High Availability (HA) status detection from /etc/pve/ha/*.cfg - Root filesystem type detection (ZFS/btrfs/ext4/xfs/LVM combinations) - Storage types enumeration from /etc/pve/storage.cfg (anonymous, no IDs) - Improved CPU topology detection: - Fixed physical CPU socket counting (unique physical IDs only) - Added cores per socket calculation - Added threads per core detection (SMT/Hyperthreading) - Enhanced validation with fallback logic - Enhanced GPU VRAM metrics: - Total VRAM across all GPUs - Min/max/average VRAM calculations - VRAM known count for accurate statistics **Improvements:** - Better error handling for telemetry failures in support mode - Verbose telemetry logging with detailed payload/response display - Enhanced local development mode with full telemetry debugging - Improved HMAC signature generation with multiple fallback methods (xxd/od/openssl) - Support token generation from Instance ID for easier support correlation - Date updated in header from 2025-11-25 to 2025-12-10 **Privacy & Compliance:** - All new metrics maintain GDPR compliance (no personal data collected) - Storage types collected without IDs, names, or paths - Subscription mode detection doesn't expose license keys - HA detection only confirms presence, no configuration details **User Experience:** - Clear visual feedback for support mode with bordered output - Color-coded messages for better readability - Helpful retry instructions on telemetry failures - Support token display for easy copy-paste to support team - JSON preview with syntax highlighting in terminal **Technical Details:** - HMAC signature validation enhanced (checks for 64-char hex format) - JSON payload validation before sending - Telemetry event logging for all operations - Graceful degradation when optional tools (xxd/od) unavailable - Support for both interactive and non-interactive modes This update significantly improves transparency and debuggability while maintaining strict privacy standards and providing better support workflows.
