Python Fabric记录错误

Question

I am trying to understand how fabric's logger module works. I run on the command line:

 $ fabfile -I task-1

I of course get output to the console showing me the execution of the task on each of the remote hosts connected to. Bu how can I redirect the output of errors to a logfile on my local machine and put a timestamp on it? Does fabric's logger module provide this? Or should I use Python's logging module. Either one, I am not sure how to implement.

Unfortunately, Fabric does not feature logging to a file (see issue #57 )

But there is a workaround using the logging module, which I find pretty nice.

First, configure your logger:

import logging

logging.basicConfig(
    level=logging.DEBUG, format='%(asctime)s:%(levelname)s:%(name)s:%(message)s',
    filename="out.log",
    filemode='a'
)

And then wrap the portions of your code which are likely to throw errors with a try/catch block like this:

try:
    #code
except:
    logging.exception('Error:')

The logger will print 'Error:' and the exception's stacktrace to "out.log"
