Not to bring up old issues but, I am trying to format my logs. I read the
wiki attached to this thread and I have this configuration working in my
weewx.conf:
# ===== LOGGING SETUP (Configured 09/04/2021) =====
[Logging]]
[[root]]
handlers = rotate,
[[loggers]]
[[handlers]]
[[[rotate]]]
level = INFO
formatter = standard
class = logging.handlers.RotatingFileHandler
filename = /mnt/sandisk_512_ssd/weewx/logs/weewx.log
maxBytes = 1000000
backupCount = 10
# ===== END LOGGING SETUP =====
But I want to format the logging out using a custom formatter as such:
# ==== PROPOSED CHANGE TO MY WEEWX.CONF =====
[Logging]
[[formatters]]
[[[ddj]]]
format =
'%(asctime)s [%(levelname)s] [%(threadName)s] [%(name)s : %(funcName)s]
%(message)s'
[[root]]
handlers = rotate,
[[loggers]]
[[handlers]]
[[[rotate]]]
level = INFO
formatter = ddj
class = logging.handlers.RotatingFileHandler
filename = /mnt/sandisk_512_ssd/weewx/logs/weewx.log
maxBytes = 1000000
backupCount = 10
# ===== END LOGGING SETUP =====
I am running Weewx 4.5.1 on a Raspberry Pi using Raspbian O/S (32bit) which
is essentially Debian buster.
Is there a way to express a formatter in the weewx.conf file so the logging
object will format the results for me?
