[英]Python Logging - How do I disable a package's Logging?
I am being driven mad by this issue.我被这个问题逼疯了。 I want to just log using my basicConfig, but the module (uvicorn) is also logging to the file as well.我只想使用我的 basicConfig 登录,但模块 (uvicorn) 也正在登录该文件。
Example:例子:
2019-11-27 14:44:29,595 - uvicorn - INFO - ('127.0.0.1', 62211) - "GET /consumption/xyz HTTP/1.1" 200
('127.0.0.1', 62211) - "GET /consumption/xyz HTTP/1.1" 200
I don't want the 2nd message to appear because it is a duplicate...how do I disable that?我不希望出现第二条消息,因为它是重复的...我该如何禁用它?
Update: Code used...更新:代码使用...
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
logging.getLogger("snowflake.connector.network").disabled = True # remove snowflake network logging
logging.getLogger("snowflake.connector.connection").disabled = True
logging.getLogger('snowflake.connector').setLevel(logging.INFO)
logging.getLogger('boto3').setLevel(logging.INFO)
logging.getLogger('botocore').setLevel(logging.CRITICAL)
logging.getLogger('urllib3').setLevel(logging.CRITICAL)
logging.basicConfig(filename=f'{CFG.get("log_path")}',
filemode='w',
level=logging.DEBUG,
format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
)
rotating = RotatingFileHandler(f'{CFG.get("log_path")}', maxBytes=1024*1024*500, backupCount=4)
logging.getLogger('').addHandler(rotating)
Log after setting access-log = False.设置 access-log = False 后记录。 I hit the API a few times:我打了几次 API:
2019-12-02 10:16:26,635 - uvicorn - WARNING - auto-reload only works when app is passed as an import string.

Log when access_log = True: access_log = True 时记录:
2019-12-02 10:17:44,438 - uvicorn - WARNING - auto-reload only works when app is passed as an import string.

logging.basicConfig
adds a Handler
. logging.basicConfig
添加一个Handler
。 Then you go and add another.然后你去添加另一个。 Both directed to the same file.两者都指向同一个文件。
logging.basicConfig(filename=f'{CFG.get("log_path")}',
filemode='w',
level=logging.DEBUG,
format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
)
rotating = RotatingFileHandler(f'{CFG.get("log_path")}', maxBytes=1024*1024*500, backupCount=4)
logging.getLogger('').addHandler(rotating)
So to see how to fix this it is best to look at what logging.basicConfig
actually does:因此,要了解如何解决此问题,最好查看logging.basicConfig
实际执行的操作:
def basicConfig(**kwargs):
_acquireLock()
try:
if len(root.handlers) == 0:
filename = kwargs.get("filename")
if filename:
mode = kwargs.get("filemode", 'a')
hdlr = FileHandler(filename, mode)
else:
stream = kwargs.get("stream")
hdlr = StreamHandler(stream)
fs = kwargs.get("format", BASIC_FORMAT)
dfs = kwargs.get("datefmt", None)
fmt = Formatter(fs, dfs)
hdlr.setFormatter(fmt)
root.addHandler(hdlr)
level = kwargs.get("level")
if level is not None:
root.setLevel(level)
finally:
_releaseLock()
Inlining basicConfig
results in:内联basicConfig
结果:
root = logging.getLogger('')
if len(root.handlers) == 0:
filename = f'{CFG.get("log_path")}'
mode = 'w'
hdlr = FileHandler(filename, mode)
fs = '%(asctime)s - %(name)s - %(levelname)s - %(message)s'
dfs = None
fmt = Formatter(fs, dfs)
hdlr.setFormatter(fmt)
root.addHandler(hdlr)
root.setLevel(logging.DEBUG)
rotating = RotatingFileHandler(f'{CFG.get("log_path")}', maxBytes=1024*1024*500, backupCount=4)
root.addHandler(rotating)
Can you see the issue?你能看出问题吗? The same file is setup with a Handler
twice so to fix this write it as:同一个文件使用Handler
设置了两次,因此要修复此问题,请将其写为:
root = logging.getLogger('')
if len(root.handlers) == 0:
filename = f'{CFG.get("log_path")}'
hdlr = RotatingFileHandler(filename, maxBytes=1024*1024*500, backupCount=4)
fs = '%(asctime)s - %(name)s - %(levelname)s - %(message)s'
fmt = Formatter(fs)
hdlr.setFormatter(fmt)
root.addHandler(hdlr)
root.setLevel(logging.DEBUG)
