I'm trying to add some extra fields to logging, I'm following this
information [1] but it faills in my case.
# module logger.py
--------------------
import logging
class ExtraInfo(object):
def __getitem__(self, name):
if name == 'host':
result = 'foo'
def __iter__(self):
keys = ['host',]
keys.extend(self.__dict__.keys())
return keys.__iter__()
def setup(filename='/tmp/foo.log'):
log = logging.LoggerAdapter(logging.getLogger('foo'), ExtraInfo())
#log = logging.LoggerAdapter(logging.getLogger('foo'), {'host':
'bar'})
logging.basicConfig(
level=logging.DEBUG,
format=(
"Date-Time: %(asctime)s\n"
"Host: %(host)s\n"
"%(levelname)s:\n"
"%(message)s"),
# %f => microseconds is not showed, bug?
datefmt="%Y-%m-%dT%H:%M:%S%z",
filename=filename,
filemode='w')
--------------------
# module another.py
--------------------
import logger
logger.setup()
logging.getLogger('foo')
logging.error('testing ...')
--------------------
I get => KeyError: 'host'
