Jul 1, 2025July 2025: Delivered two high-impact features in blazingmq, with improvements to monitoring accuracy and search capabilities. Refactored MQBBLP consumption monitor to a timer-based mechanism, reducing false positives; StorageTool search now defaults to all record types for Journal/CSL modes and supports exact-match filtering by offset/sequence number, with docs and parameter parsing updates. These changes enhance operational visibility, reduce troubleshooting time, and improve developer experience.

Apr 1, 2025April 2025 (2025-04) monthly summary for bloomberg/blazingmq: Delivered a key feature to enhance observability and capacity planning by exposing queue utilization metrics via Prometheus. This involved calculating the maximum percentage of messages and bytes in a queue relative to its configured capacity and surfacing these metrics through the mqbstat_queuestats component to the Prometheus consumer. No major bugs fixed this period. The work contributes to more reliable service operation and data-driven capacity management.
