File logging is a method used by software applications to record events, errors, and other important information in a text file. This process helps developers and system administrators track the behavior of the application, making it easier to diagnose issues and monitor performance over time. The log files can be reviewed later to understand what happened during specific events or to identify patterns. Typically, file logging includes timestamps, log levels (like INFO, WARNING, or ERROR), and descriptive messages. This structured approach allows users to filter and search through logs efficiently. Many programming languages and frameworks provide built-in support for file logging, making it a common practice in software development.
