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.

RS( sf Log formatter used in Tornado.
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` (unless ``--logging=none`` is
used).

:arg bool color: Enables color support.
:arg string fmt: Log message format.
It will be applied to the attributes dict of log records. The
text between ``%(color)s`` and ``%(end_color)s`` will be colored
depending on the level if color support is on.
:arg dict colors: color mappings from logging level to terminal color
code
:arg string datefmt: Datetime format.
Used for formatting ``(asctime)`` placeholder in ``prefix_fmt``.
.. versionchanged:: 3.2
Added ``fmt`` and ``datefmt`` arguments.
