Apr 1, 2025In April 2025, delivered enhanced error logging for Bedrock request bodies to improve debugging and resilience. Implemented structured logging across logging functions and parsed exception bodies as JSON prior to logging, boosting readability and context in error reports. Updated BedrockCore.cpp to support the new logging flow. Changes tracked across two commits: a437ed2230947fe4f8e8a95399190654d3e26ea9 ('Seperate out the body') and 88f37d8f1641b8922750114e8e9864f82171b6f6 ('Update BedrockCore.cpp').

Nov 1, 2024November 2024: Delivered enhanced logging to enable detailed performance and timing analysis. Expanded Bedrock logging whitelist with timeDiff, currentTime, and requestTimestamp in SLog.cpp (PARAMS_WHITELIST), enabling deeper observability, faster root-cause analysis, and data-driven performance optimization. This groundwork supports future performance dashboards and SLA-driven improvements.
