A root logger is not that different to any other logger, except that it must have a logging level and there is only one instance of it in the hierarchy.
There are no implemented interfaces.

addFilter(filter)
Add the specified filter to this handler.
addHandler(hdlr)
Add the specified handler to this logger.
callHandlers(record)
Pass a record to all relevant handlers.
Loop through all handlers for this logger and its parents in the logger hierarchy. If no handler was found, output a one-off error message to sys.stderr. Stop searching up the hierarchy whenever a logger with the "propagate" attribute set to zero is found - that will be the last logger whose handlers are called.
critical(msg, *args, **kwargs)
Log msg % args
with severity CRITICAL
.
To pass exception information, use the keyword argument exc_info with a true value, e.g.
logger.critical("Houston, we have a %s", "major disaster", exc_info=1)
debug(msg, *args, **kwargs)
Log msg % args
with severity DEBUG
.
To pass exception information, use the keyword argument exc_info with a true value, e.g.
logger.debug("Houston, we have a %s", "thorny problem", exc_info=1)
error(msg, *args, **kwargs)
Log msg % args
with severity ERROR
.
To pass exception information, use the keyword argument exc_info with a true value, e.g.
logger.error("Houston, we have a %s", "major problem", exc_info=1)
exception(msg, *args)
Convenience method for logging an ERROR with exception information.
fatal(msg, *args, **kwargs)
Log msg % args
with severity CRITICAL
.
To pass exception information, use the keyword argument exc_info with a true value, e.g.
logger.critical("Houston, we have a %s", "major disaster", exc_info=1)
filter(record)
Determine if a record is loggable by consulting all the filters.
The default is to allow the record to be logged; any filter can veto this and the record is then dropped. Returns a zero value if a record is to be dropped, else non-zero.
findCaller()
Find the stack frame of the caller so that we can note the source file name, line number and function name.
getEffectiveLevel()
Get the effective level for this logger.
Loop through this logger and its parents in the logger hierarchy, looking for a non-zero logging level. Return the first one found.
handle(record)
Call the handlers for the specified record.
This method is used for unpickled records received from a socket, as well as those created locally. Logger-level filtering is applied.
info(msg, *args, **kwargs)
Log msg % args
with severity INFO
.
To pass exception information, use the keyword argument exc_info with a true value, e.g.
logger.info("Houston, we have a %s", "interesting problem", exc_info=1)
isEnabledFor(level)
Is this logger enabled for level level
?
log(level, msg, *args, **kwargs)
Log msg % args
with the integer severity level
.
To pass exception information, use the keyword argument exc_info with a true value, e.g.
logger.log(level, "We have a %s", "mysterious problem", exc_info=1)
makeRecord(name, level, fn, lno, msg, args, exc_info)
A factory method which can be overridden in subclasses to create specialized LogRecords.
removeFilter(filter)
Remove the specified filter from this handler.
removeHandler(hdlr)
Remove the specified handler from this logger.
setLevel(level)
Set the logging level of this logger.
warn(msg, *args, **kwargs)
Log msg % args
with severity WARNING
.
To pass exception information, use the keyword argument exc_info with a true value, e.g.
logger.warning("Houston, we have a %s", "bit of a problem", exc_info=1)
warning(msg, *args, **kwargs)
Log msg % args
with severity WARNING
.
To pass exception information, use the keyword argument exc_info with a true value, e.g.
logger.warning("Houston, we have a %s", "bit of a problem", exc_info=1)
There are no known subclasses.
