If you're going to whore out parts of the string to
variables i would suggest going for the gold and actually
make it readable. Plus, your use of the format  syntax is
incorrect.

  _arg1 = settings['MONGODB_DB']
  _arg2 = settings['MONGODB_COLLECTION']
  _fmtstr = "Item wrote to MongoDB database {0}, {1}"
  msg = _fmtstr.format(_arg1, _arg2)
  log.msg(msg, level=log.DEBUG, spider=spider)

If you want readability, now you got it.
