def get_handler_stats(self):
        ''' Return handler read statistics

        Returns a dictionary of managed handler data read statistics. The
        format is primarily controlled by the
        :func:`SocketStreamCapturer.dump_all_handler_stats` function::

            {
                <capture address>: <list of handler capture statistics>
            }

        '''
        return {
            address : stream_capturer[0].dump_all_handler_stats()
            for address, stream_capturer in self._stream_capturers.iteritems()
        }
