My question is simple: what to write into a log. Are there any conventions? What do I have to put in?
Since my app has to be released, I'd like to have friendly logs, which could be read by most people without asking what it is.
I already have some ideas, like a timestamp, a unique identifier for each function/method, etc.. I'd like to have several log levels, like tracing/debugging, informations, errors/warnings.
Do you use some pre-formatted log resources?
Thank you

The JSON (JavaScript Object Notation) is a highly readable data-interchange format that has established itself as the standard format for structured logging. It is compact and lightweight, and simple to read and write for humans and machines.
Logs files are a historical record of everything and anything that happens within a system, including events such as transactions, errors and intrusions. That data can be transmitted in different ways and can be in both structured, semi-structured and unstructured format.
It's quite pleasant, and already implemented.

Edit
"easy to parse, read," are generally contradictory features. English -- easy to read, hard to parse. XML -- easy to parse, hard to read. There is no format that achieves easy-to-read and easy-to-parse. Some log formats are "not horrible to read and not impossible to parse".
Some folks create multiple handlers so that one log has several formats: a summary for people to read and an XML version for automated parsing.
