Hi @BrunoQuaresma! Apologies for the slow reply here. Personally I’m a huge proponent of logging and I know this will eventually become a critical feature for Redwood to integrate. I just don’t think many people are far enough along yet to be thinking about it.
My last project used Docker/Kubernetes, and I set up Papertrail via Fluentd. Unfortunately, that doesn’t give me much insight into how this needs to work in the world of Lambdas and Browsers.
As far as “more app pieces”, if you’re logging each individual lambda function (so each file in api/src/functions), that seems like a majority of the coverage you’d need. Personally I’d 
to get browser console logs, but I have no idea of examples of this outside using Fullstory session tracking including console errors.
Lastly, I wonder if there’s a way to tap into the logs Netlify is already keeping (but not for longer than one hour)?
Have you taken any further steps since writing this?
