Original GitHub issue: https://github.com/karakeep-app/karakeep/issues/2016

Describe the feature you'd like

Standard LOG_LEVEL setting would be handy, as would an env var to control log format. Specifically, it would be great to have an option to log to JSON format.

Describe the benefits this would bring to existing Karakeep users

Easier handling of log messages and ingestion into log aggregation services.

Can the goal of this request already be achieved via other means?

Nope

Have you searched for an existing open/closed issue?

I have searched for existing issues and none cover my fundamental request

Additional context

No response

I would add here that it would be great to have separately control over actual application log and the access log. For example, I also have the access log from the reverse proxy, therefore I would like to be able to completely disable it in karakeep.

Great point. I agree. My logs are spammed by messages related to the healthcheck "GET /api/health ...".

I ran into this as well. After testing, I wanted to suppress all debug logging and did not find any related environment variable in the docs.

However, the linked config.ts does indeed specify a LOG_LEVEL field.

Looking at the winston docs, I just added a LOG_LEVEL=warning to my .env and this seems to just work for now.

To me, this look like it's just missing in the documentation, I think I might open a PR for this.

@petrm @codersaur You should be able to change the log level setting the way I described. Please take a look at #2166 🙂
