Tornado uses three logger streams: * ``tornado.access``: Per-request logging for Tornado's HTTP servers (and potentially other servers in the future) * ``tornado.application``: Logging of errors from application code (i.e. uncaught exceptions from callbacks) * ``tornado.general``: General-purpose logging, including any errors or warnings from Tornado itself. These streams may be configured independently using the standard library's `logging` module. For example, you may wish to send ``tornado.access`` logs to a separate file for analysis.

Key features of this formatter are: * Color support when logging to a terminal that supports it. * Timestamps on every log line. * Robust against str/bytes encoding problems. This formatter is enabled automatically by `tornado.options.parse_command_line` or `tornado.options.parse_config_file` (unless ``--logging=none`` is used). Color support on Windows versions that do not support ANSI color codes is enabled by use of the colorama__ library. Applications that wish to use this must first initialize colorama with a call to ``colorama.init``. See the colorama documentation for details. __ https://pypi.python.org/pypi/colorama .. versionchanged:: 4.5 Added support for ``colorama``.
