Args

logdev: The log device. This is a filename (String), IO object (typically STDOUT, STDERR, or an open file), nil (it writes nothing) or File::NULL (same as nil).
shift_age: Number of old log files to keep, or frequency of rotation (daily, weekly or monthly). Default value is 0, which disables log file rotation.
shift_size: Maximum logfile size in bytes (only applies when shift_age is a positive Integer). Defaults to 1048576 (1MB).
level: Logging severity threshold. Default values is Logger::DEBUG.
progname: Program name to include in log messages. Default value is nil.
formatter: Logging formatter. Default values is an instance of Logger::Formatter.
datetime_format: Date and time format. Default value is ‘%Y-%m-%d %H:%M:%S’.
binmode: Use binary mode on the log device. Default value is false.
shift_period_suffix: The log file suffix format for daily, weekly or monthly rotation. Default is ‘%Y%m%d’.
