feat(metrics): add system uptime monitoring collector (#217)#250
Merged
Conversation
Implement cross-platform system uptime monitoring to track boot time and system availability for SLA compliance and stability analysis. - Add uptime_collector with uptime_info_collector pattern - Linux: Read /proc/uptime for uptime and idle seconds - macOS: Use sysctl(KERN_BOOTTIME) for boot timestamp - Windows: Use GetTickCount64() for uptime calculation - Add comprehensive unit tests (18 tests passing) Metrics collected: - system_uptime_seconds: Time since boot - system_boot_timestamp: Unix timestamp of last boot - system_idle_seconds: Total idle time (Linux only)
- Add system uptime monitoring section to FEATURES.md - Add uptime_collector API reference to API_REFERENCE.md - Update CHANGELOG.md and CHANGELOG_KO.md with new feature
