What is the typical use of the TRACE logging level?

The TRACE logging level is typically used for fine-grained logging, providing detailed insights into the application's behavior, particularly around method execution. Specifically, logging at the TRACE level allows developers to capture method entry and exit points, along with any useful parameters or return values associated with those methods. This level of detail is invaluable for debugging and understanding the flow of execution through the application.

By using TRACE logging, developers can track how the application progresses through various methods, which can help pinpoint where things might go wrong, especially in complex code paths. It is critical for scenarios where a deep understanding of method calls and their interactions is necessary, such as performance tuning or diagnosing intricate bugs.

Other levels of logging, like ERROR or WARN, serve different purposes, such as capturing configuration problems, runtime failures, or potential user experience issues, which focus on more significant and broader problems rather than the detailed method-level tracing provided by TRACE logs.
