Are you using server side rendering? If so, did you end up writing a custom server, or are you monitoring your website some other way?
My team is developing a server-rendered nextjs app which is deployed on AWS. We haven't really configured it beyond the defaults, but nextjs seems to provide very little visibility into what's happening (e.g., no request logs).
If you could share any tips or lessons learned from operating a production nextjs app, it would be much appreciated.
