Specifies the level of logging to use for the log (trace) file produced by the node.

The default is Off. The value Information means log informational, the value Errors Only means log error messages only, and the value Verbose means log debug and trace level messages along with the informational and error messages.

When Append Log is set to true, the log messages are appended to the file. When set to false, the file is truncated and the messages are written to the empty file. If the file path is not specified, the trace is logged to the default system logger.
