[Dhruvkumar-Microsoft]

Purpose

This pull request primarily adds improved logging and debugging output across several API and plugin functions to aid in monitoring and troubleshooting. The changes also include minor adjustments to resource configuration in infrastructure code. The most important changes are grouped below:

API and Plugin Logging Enhancements:

• Added detailed print and logger statements to conversation in api_routes.py to log incoming chat requests and their IDs, improving traceability.
• Enhanced error handling in plugin functions (get_database_metrics, get_call_insights, and generate_chart_data in chat_with_data_plugin.py) by logging exceptions and responses, making debugging easier when failures occur. [1] [2] [3] [4] [5]
• Added logging of history metadata and request lifecycle events in stream_chat_request and complete_chat_request methods of chat_service.py, providing more visibility into chat processing. [1] [2]

Infrastructure Configuration:

• Modified the skuCapacity logic in the webServerFarm module in main.bicep so that scalability no longer increases capacity, possibly reflecting a change in scaling strategy.
