    This is a log4j 2 configuration file.

    Please keep the original "debug.log" as is, to make sure enough data is captured in of case errors
    in a format that neo4j support engineers and developers can work with. Changing the "debug.log" format
    can interfere with neo4j's ability to offer customer support and invalidate your support warranty.

    If you require the "debug.log" messages in a different format you can copy the Appender and change the
    filename. See Neo4j documentation.

    All configuration values can be queried with the lookup prefix "config:". You can for example, resolve
    the path to your neo4j home directory with ${config:dbms.directories.neo4j_home}.

    Please consult https://logging.apache.ac.cn/log4j/2.x/manual/configuration.html for instructions and
    available configuration options.
