    • ERROR: An application continues to function.

    • WARN: Not an error, but can cause a problem.

    • INFO: Information used to trace an application's operations. In general, it records coarse-grained logs, for example, API calls.

    • DEBUG: Records fine-grained logs used to debug applications. For example, it logs parameters and temporary values used during calculations.

    • TRACE: Records more detailed information than DEBUG. For example, it records extended logs related to unconventional binary data dumps or memory dumps.

    Used if DSN file path cannot be referenced through TB_HOME because only the client is installed without the server.

    TB_DSN_FILE takes priority over TB_HOME.
