LogStufe

LogStufe is a German term that translates to "log level" in English. It refers to the severity or importance assigned to a log message generated by a software application or system. Log levels are used to categorize messages and control how much information is recorded and displayed. This helps developers and administrators manage the volume of log data and focus on the most critical events.

Commonly, log levels range from least severe to most severe. A typical hierarchy might include DEBUG, INFO, WARN (or WARNING), ERROR, and FATAL (or CRITICAL). DEBUG messages provide detailed information useful for developers during the debugging process. INFO messages indicate normal operational progress. WARN messages signal potential problems that do not prevent the application from functioning but might require attention. ERROR messages indicate that a specific operation has failed. FATAL messages signify a severe, unrecoverable error that typically causes the application to terminate.

By configuring the desired log level, users can control the verbosity of the logging output. For instance, setting the log level to ERROR will only record error and fatal messages, significantly reducing the amount of log data. Conversely, setting it to DEBUG will capture all messages, providing the most comprehensive view. This flexibility is crucial for performance, storage management, and efficient troubleshooting. Many logging frameworks allow dynamic adjustment of log levels without requiring an application restart.
