Aspectow AppMon 3.2 Release Notes

This release focuses on adding PostgreSQL support, enhancing the flexibility of the persistence layer, improving chart data accuracy through refined aggregation logic, and a comprehensive overhaul of the configuration structure and operational scripts to strengthen the project’s identity.

✨ New Features

• PostgreSQL Support and Optimization: Added a standard schema for PostgreSQL environments (e.g., Supabase) and implemented optimized queries using date_trunc and ON CONFLICT for efficient time-series aggregation and atomic upserts.
• Enhanced Persistence Architecture: Refactored EventCountMapper and its implementation to support bean overriding, allowing external projects to provide custom persistence logic without modifying the core library.

🚀 Improvements

• Enhanced Chart Data Accuracy: Removed the daily aggregation table (appmon_event_count_daily) and switched entirely to hourly source data for all aggregated charts (Daily, Monthly, Yearly). Applied zoneOffset to all aggregations to ensure data is correctly grouped according to the user’s local time zone, eliminating discrepancies caused by UTC boundaries.
• Configuration Refactoring and New Naming Convention: Renamed the configuration resource directory from context to config and transitioned Spring-style *-context.xml files to concise, functional names like database.xml and scheduler.xml to reinforce Aspectran’s rule-based identity.
• Consolidated Service Management and Script Refinement: Added service.sh as a unified wrapper for systemctl and refined script logic for better process management and automatic lock cleanup. Updated shell scripts to display environment information only when the --debug flag is provided, reducing console noise.
• Updated Dependency Versions: Updated key plugin versions including maven-resources-plugin (3.5.0), maven-surefire-plugin (3.5.5), and maven-bundle-plugin (6.0.2) to ensure build and test stability.
