Poem

🐇 In the logs, a message clear,
Errors caught, no need to fear.
With structured lines, we now can see,
What went wrong, oh joy, oh glee!
A rabbit hops, with logs so bright,
Celebrating code, all day and night! 🌟

    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Line range hint 56-74: Consider enhancing error context with structured logging

While the logging improvements are good, consider adding more context to help with debugging and monitoring. You could include relevant information such as facilityId and operation metadata using structured logging.

Example enhancement:

-            Logger.LogError(ex, "Error occurred while processing the message");
+            Logger.LogError(ex, "Error occurred while processing the message for facility {FacilityId}", facilityId);

Similarly for the producer error:

-            Logger.LogError(ex, "Error occurred while attempting to produce a message");
+            Logger.LogError(ex, "Error occurred while attempting to produce message for facility {FacilityId} to topic {Topic}", 
+                facilityId, KafkaTopic.PatientIDsAcquired);
DotNet/Shared/Application/Error/Handlers/TransientExceptionHandler.cs (1)

69-69: Consider including exception details in the log message.

While the structured logging format is good, consider including the exception message in the log for better debugging context:

-Logger.LogError(ex, "{Name}: Failed to process {ServiceName} Event.", GetType().Name, ServiceName);
+Logger.LogError(ex, "{Name}: Failed to process {ServiceName} Event. Error: {ErrorMessage}", GetType().Name, ServiceName, ex.Message);

🛠️ Refactor suggestion

Fix the logging statement format

Similar to the previous logging statement, this one has incorrect placeholder indexing and redundant message logging.

Apply this change for better structured logging:

-            Logger.LogError(ex, "Error occurred while attempting to produce a message: {1}", ex.Message);
+            Logger.LogError(ex, "Error occurred while attempting to produce a message");

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Improve the logging statement format

The current logging statement has incorrect placeholder indexing and redundant message logging. The exception message is already included when passing the exception object as the first parameter.

🛠️ Refactor suggestion

Fully adopt structured logging format.

The current implementation mixes structured logging with string concatenation. Consider using structured logging consistently:

-Logger.LogError(e, "Error in {Name}.HandleException: " + e.Message, GetType().Name);
+Logger.LogError(e, "Error in {Name}.HandleException: {ErrorMessage}", GetType().Name, e.Message);
