January 2025 monthly summary for openMF/fineract: Delivered two core features to improve asset settlement handling and system observability. Implemented Loan Product Settlement Association, adding API endpoints and backend logic to attach settlement information to loan products for externally owned assets. Implemented Tenant-level Metrics Tracking for DB Connection Pools using Micrometer, exposing per-tenant pool statistics by updating data source factories to register metrics. These changes enable accurate settlement processing, granular tenant observability, and data-driven capacity planning. Business value includes improved settlement accuracy for externally owned assets, better SLA readiness through enhanced monitoring, and empowered operations with per-tenant resource visibility. Technical highlights include API surface expansion, new settlement attributes configuration, Micrometer integration, and per-tenant metrics registration. Commits: FINERACT-2081; FINERACT-2166.
