fix: improves observability of provider websocket#1751
Conversation
WalkthroughThe changes introduce structured logging for certificate validation outcomes within the WebSocket server, emitting specific log events for valid, invalid, and prematurely closed connections. Additionally, callback functions in asynchronous message proxying are wrapped with tracing context propagation to maintain observability during WebSocket operations. Changes

336-343: LGTM! Good observability for premature WebSocket closure.The structured logging effectively captures the edge case where a WebSocket closes during certificate validation. The warn level is appropriate as this could indicate network issues or race conditions.
Note: The event name "PROVIDER_WEBSOCKET_CLOSED" is also used at line 406 for normal WebSocket closure. Consider using a more specific event name like "PROVIDER_WEBSOCKET_CLOSED_DURING_VALIDATION" to distinguish between normal closure and premature closure during validation for better observability.

244-255: LGTM! Proper tracing context propagation implementation.The callback functions are correctly wrapped with
propagateTracingContextto ensure tracing context is maintained during asynchronous WebSocket operations. This aligns with the observability improvements mentioned in the PR objectives.
318-324: LGTM! Well-structured logging for certificate validation failures.The structured logging provides clear observability into certificate validation failures with appropriate contextual information. The use of warn level and the event name "PROVIDER_INVALID_CERTIFICATE" makes it easy to monitor and alert on certificate issues.
330-335: LGTM! Appropriate logging for successful certificate verification.The debug-level structured logging for successful certificate verification provides valuable observability without being too verbose. The event name and contextual information are well-chosen for monitoring certificate validation outcomes.
