Oct 1, 2025October 2025 monthly summary for TencentBlueKing/bk-monitor focused on delivering robust observability, reliable configuration management, and deployment efficiency. Key changes include: (1) APM Metrics reliability, configurability, and data collection improvements with retry on application creation, ability to disable default reporting for centralized clusters, whitelist-based metric collection, exclusion of user API visits from analytics, and temporary removal of certain metrics during a six-month refinement period (including temporary removal of derived metrics bk_apm_duration_bucket and related page displays). (2) Secrets management reliability in BkCollectorClusterConfig by updating namespaced secrets via replacement to prevent duplicates and ensure clean, idempotent updates. (3) Docker build optimization through Dockerfile refactor to install tooling earlier in the build process, speeding up image creation and ensuring dependencies are ready for later steps. Commit references span across the APM feature and fixes, secret management, and Dockerfile optimization to support these deliveries.
