A logging framework is a software tool that helps developers record and manage log messages generated by applications. These messages can provide insights into the application's behavior, performance, and errors, making it easier to troubleshoot issues. Common logging frameworks include Log4j, SLF4J, and Logback, which offer various features like log levels, formatting, and output destinations. Using a logging framework allows developers to standardize how logs are created and stored, improving consistency across different parts of an application. It also enables easy integration with monitoring tools and services, enhancing the overall observability of the system.
