Question: Can I add request-id into uvicorn.access log?

[tienhm0202]

My log now is:

[2021-04-25 08:48:58 +0000] [13] [INFO] RID: ad303ddacea942b89c6f08e33b5f09be | CID: d68deb856ea84d4e8e7bc7c08bc511bd | s.m.users.business.controllers | An user is trying to log in our system

[2021-04-25 08:48:58 +0000] [13] [INFO] uvicorn.access | 172.21.0.1:64268 - "POST /v1/users/login HTTP/1.1" 200

I tried to add filter to log request-id and correlation-id to uvicorn.access but it raised starlette_context.errors.ContextDoesNotExistError.

Is there a way to add context data to uvicorn.access log?

Look like context is closed right in RawContextMiddleware - I will try another

Yes, it's not possible to use context in uvicorn.

You can see it's still changing. A few months ago the behavior you desire was there by default and now it's not even possible to add headers to logs if I read it correctly. If I were you I'd not rely on uvicorn logs AT ALL but rather add a proxy server where you will have total control over it and much more. Then, send logs to a centralized server.

So if you're willing to overengineer it:

• add traeffic / caddy
• add ELK or something else where you can browse logs

Or just use 0.13.0 where I believe the response scope was logged.

Note I'm not an expert on this topic. If you come up with a solution to your problem, please let me know. I might be wrong about app/server layers and maybe it's possible to glue them together 🤷🏻‍♂️
