The default logging configuration includes a syslog handler. While you're
trying to override that with a weewx.conf spec, the override gets *merged* into
the default configuration. So, the syslog handler never goes away.
Unfortunately, the way the Python handlers work, all specified handlers get
instantiated whether or not they will actually get used. No just-in-time
creation here. So the mere presence of the syslog handler could be causing
the problem. Or, maybe not.
A possible workaround. Put this in user/extensions.py. It basically removes
completely the specification of a syslog handler from the default handler.
import weeutil.logger
weeutil.logger.LOGGING_STR = """[Logging]
version = 1
disable_existing_loggers = True
[[loggers]]
# Root logger
[[[root]]]
level = {log_level}
propagate = 1
handlers = console,
# Definitions of possible logging destinations
[[handlers]]
# Log to console
[[[console]]]
level = DEBUG
formatter = verbose
class = logging.StreamHandler
# Alternate choice is 'ext://sys.stderr'
stream = ext://sys.stdout
# How to format log messages
[[formatters]]
[[[simple]]]
format = "%(levelname)s %(message)s"
[[[standard]]]
format = "{process_name}[%(process)d] %(levelname)s %(name)s:
%(message)s"
[[[verbose]]]
format = "%(asctime)s {process_name}[%(process)d]
%(levelname)s %(name)s: %(message)s"
# Format to use for dates and times:
datefmt = %Y-%m-%d %H:%M:%S
"""
See if that helps.
As for disable_existing_loggers, its exact function isn't very clear from
the documentation, at least to me, but it seems like in this case you want
it True.
