Jan 1, 2025January 2025 (2025-01) - CloudDetail/apo: Delivered Alert Processing Enhancements, improving robustness of default enrichment rules, refactoring alert tag mapping for maintainability, and tightening infra alert filtering to ensure same-node correlation for precise retrieval. Completed three alert-related bug fixes aligned with this feature: set alertSource as the default source, updated SQL scripts for alert tag mapping, and restricted infra alert searches to the same node. Result: more reliable alerts, faster triage, and better observability with maintainable code across the alerting stack.

Dec 1, 2024December 2024 (CloudDetail/apo): Implemented robust SQL query filtering logic to ensure correctness after refactoring. Key improvements include proper merging of WHERE clauses to handle all-true and all-false conditions, and a safe default of ALWAYS_TRUE when no filters are provided, preventing unintended queries. The fix ensures empty filter scenarios don’t trigger all-events queries and aligns query behavior with expected filter semantics across the alerting workflow. This work reduces data over-fetch, improves reliability, and strengthens data access guarantees for alerting.
