Description

Currently, some destinations send events directly from the router, while others send events through transformer. When customers request specific information for debugging, the data is often not readily available. This PR aims to address that issue.

We propose adding logging capabilities for these destinations. The logs will capture the destination's response body, status code, and headers.

This feature will be configurable, requiring the service owner to specify the destType, destinationId, or workspaceId. When an event's data matches any of these criteria, the response information will be logged.

Note: The service owner must enable this logging feature for it to take effect.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • 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 generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @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.

do we need a log for all events or a filter for only failed events?

Log for all events as we would like to know the request IDs to share the information with users when needed

won't this effect rudder-server performance?

Logging the requests would definitely affect functionality of any service but the need of the hour is that we need to supply the request information details to users when needed. Let me know if there is any other way of tackling this

@rudderlabs/server_team is it ok if we enable logging for some duration and log all event responses from the destination

any other way of tackling this

Admittedly without the entire context, it does look like a good candidate for reporting data.
If we're okay with sampled data, going thru reporting data for sample response with all the mentioned filters(destType, destinationId, or workspaceId) should be good imo.

Here, we are interested in getting information about the destination's response(when delivered via router) like requestIds, the actual response that we got from destination, any other information that destination sent us.
I don't think sampling actually serves the requirement.

Any user might need these information for a specific set of time range & they would need all the information & not samples.

@sanpj2292 , I don't think it's a great idea to log each and every response. Also, polluting code and configurations just for logging purposes.
Also, I do see we're logging res body which probably might contain PII information which we should avoid logging.
Can you share any customer requests where customers needed this info?
Is it possible to explore the path Siddharth mentioned above? may be we can enrich reporting sampled data with some more info?
