How do you log in your projects?

[Marco Sulla]

These are a lot of questions. I hope we're not off topic.
I don't know if mine are best practices. I can tell what I try to do.

I usually log the start and end of functions. I could also log inside
a branch or in other parts of the function/method.

No, since I put the function parameters in the first log. But I think
that such a decorator it's not bad.

Well, all the data that is useful to understand what the code is
doing. It's better to repeat the essential data to identify a specific
call in all the logs of the function, so if it is called
simultaneously by more clients you can distinguish them

It depends on the importance, the verbosity and the occurrences of the logs.

I have the opposite problem, I should log more. So I can't answer your question.
