如何在Python中为导入的模块定义其他记录器? [英] How do I define a different logger for an imported module in Python?

问题描述

我在Python脚本中使用高级Python计划程序.主程序通过使用我想要的日志文件名调用logging.basicConfig来定义日志.该日志也设置为"DEBUG"作为日志记录级别，因为这是我目前对脚本的需求.

I'm using Advanced Python Scheduler in a Python script. The main program defines a log by calling logging.basicConfig with the file name of the log that I want. This log is also set to "DEBUG" as the logging level, since that's what I need at present for my script.

不幸的是，由于logging.basicConfig是以这种方式设置的，因此apscheduler会将其日志条目写入同一日志文件.其中有很多，尤其是因为我有一个预定的任务每分钟运行一次.

Unfortunately, because logging.basicConfig has been set up in this manner, apscheduler writes its log entries to the same log file. There are an awful lot of these, especially since I have one scheduled task that runs every minute.

在将日志文件用于自己的脚本时，是否可以将apscheduler的日志输出重定向到另一个日志文件(无需更改apscheduler的代码)?IE.有没有办法在我的脚本中更改每个模块输出的文件名?

Is there any way to redirect apscheduler's log output to another log file (without changing apscheduler's code) while using my log file for my own script? I.e. is there a way to change the file name for each module's output within my script?

我尝试阅读模块页面和HOWTO日志记录，但找不到答案.

I tried reading the module page and the HOWTO for logging, but could not find an answer to this.

推荐答案

将 apscheduler 的记录器级别设置为所需的值(例如， WARNING ，以避免看到DEBUG和INFO来自 apscheduler 的消息，如下所示:

Set the logger level for apscheduler to your desired value (e.g. WARNING to avoid seeing DEBUG and INFO messages from apscheduler like this:

logging.getLogger('apscheduler').setLevel(logging.WARNING)

您仍然会收到有关 WARNING 和更高严重性的消息.要将邮件从 apscheduler 定向到一个单独的文件中，请使用

You will still get messages for WARNING and higher severities. To direct messages from apscheduler into a separate file, use

aplogger = logging.getLogger('apscheduler')
aplogger.propagate = False
aplogger.setLevel(logging.WARNING)    # or whatever
aphandler = logging.FileHandler(...)  # as per what you want
aplogger.addHandler(aphandler)

确保上述代码仅被调用一次(否则，您将添加多个 FileHandler 实例-可能不是您想要的).

Ensure the above code is only called once (otherwise you will add multiple FileHandler instances - probably not what you want).
