Convert Python exception information to string for logging

Question

I try logging exceptions in Python 2.5, but I can't do it. All formatting functions do something else than what I want.

I came up with this:

def logexception(type, value, traceback):
  print traceback.format_exception(type, value, traceback)

sys.excepthook = logexception

but it bails out with an argument error when called, though according to the docs it should work. Anyone knows what the problem is with this or have an other drop-in solution?

Answer 1

you can use this very simpe logging solution

or this one

Answer 2

Why should that traceback argument have a format_exception method just like the function in the traceback module whose name it's usurping, and if it had one why would that method require the same object on which it's called to be passed in as the last argument as well?

I suspect you just want to give the third argument a different name, so as not to hide the traceback module, say:

import sys
import traceback

def logexception(type, value, tb):
  print traceback.format_exception(type, value, tb)

sys.excepthook = logexception

and things should work much better.
