Apr 1, 2026April 2026 (2026-04) — bk-monitor: Key features delivered: - Custom Metrics Dashboard and Query Enhancements: introduced a dedicated metrics page with advanced querying, flexible dimension grouping, support for data source IDs beyond APM, improved handling of missing dimension values, enhanced MySQL query compatibility, and a revamped startswith search type. This enables viewing tens of thousands of metrics on a single page and broader data-source flexibility. Major bugs fixed: - Profile Download Filter Parsing Bug: fixed the profile download serializer to correctly parse JSON filter labels from query strings so filtering conditions apply during export. - Additional stability fixes: MySQL IN-subquery compatibility issues; MySQL 5.7 compatibility fixes for APM custom metrics management page; ensured disabled metrics are not shown on the UI. Overall impact and accomplishments: - Significantly improved monitoring scalability and reliability for bk-monitor, enabling large-scale metric exploration and more accurate exports. - Reduced operator toil by correcting export filtering and expanding data-source compatibility. Technologies/skills demonstrated: - MySQL compatibility and SQL querying (IN-subqueries, 5.7 compatibility) - Advanced querying, dimension grouping logic, and defaulting for missing dimension values - Data-source integration beyond APM (bk_data_id support) - UI/UX improvements for the metrics dashboard - Collaborative engineering (multi-author commits)
