Why should sub-levels of logging categories be used?

Using sub-levels of logging categories is essential for maintaining logging organization and structure. By implementing a hierarchical logging system, developers can categorize log messages into more specific groups, which allows for a clearer and more organized logging output. This structuring helps teams easily identify where a log entry originates, as well as its significance and context within the application.

When logs are neatly categorized, it becomes significantly easier to troubleshoot issues, as developers can focus on a particular component or module of the application without wading through unrelated log messages. This structured approach also aids in applying different logging levels, where critical logs can be distinguished from informational ones, providing better control over what gets logged based on varying severity.

Thus, the implementation of sub-levels enhances the overall manageability of logs, allowing for more efficient monitoring, debugging, and maintaining the application over time.
