I'm impressed by how only a few people mentioned what I think it's the main point of application/system logging: debugging problems. Especially in small projects when you don't work 'at scale and you don't have metrics. Am I the only one that stash GBs of low-level log messages in order to diagnose bugs that occurred in the past?
