Logging
A utility wraps Python built-in loggings
class bigflow.util.log.LogFormatter
(color=True, fmt=’%(color)s[%(levelname)1.1s %(asctime)s %(module)s:%(lineno)d]%(end_color)s %(message)s’, datefmt=’%y%m%d %H:%M:%S’, colors=None)
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).
DEFAULT_FORMAT
= ‘%(color)s[%(levelname)1.1s %(asctime)s %(module)s:%(lineno)d]%(end_color)s %(message)s’-
Format the specified record as text.
The record’s attribute dictionary is used as the operand to a string formatting operation which yields the returned string. Before formatting the dictionary, a couple of preparatory steps are carried out. The message attribute of the record is computed using LogRecord.getMessage(). If the formatting string uses the time (as determined by a call to usesTime(), formatTime() is called to format the event time. If there is exception information, it is formatted using formatException() and appended to the message.
bigflow.util.log.enable_pretty_logging
(logger, level, log_file=’’, backupCount=10, maxBytes=10000000)
Turns on formatted logging output as configured.
bigflow.util.log.enable_pretty_logging_at_debug
(logger, level, log_file=’’, backupCount=10, maxBytes=10000000)
Turns on formatted logging output only at DEBUG level
