Logging is an essential part of modern software development.
日志记录是现代软件开发的重要组成部分。

Nowadays, deploying software to a production environment without implementing any form of logging is unimaginable. Doing so is equivalent to wandering through a vast city, at peak hour, with a blindfold on.
如今，在不实施任何形式的日志记录的情况下将软件部署到生产环境是不可想象的。这样做相当于在高峰时段戴着眼罩在广阔的城市中徘徊。
