def report_metric(self, name, value):
self.send_message({"<STR_LIT>": "<STR_LIT>", "<STR_LIT:name>": name, "<STR_LIT>": value})<EOL>
Report a custom metric back to Storm.

        :param name:  Name of the metric.  This can be anything.
        :param value: Value of the metric.  This is usually a number.

        Only supported in Storm 0.9.3+.

        .. note::
            In order for this to work, the metric must be registered on the
            Storm side.  See example code
            `here <https://github.com/dashengju/storm/blob/573c42a64885dac9a6a0d4c69a754500b607a8f1/storm-core/src/jvm/backtype/storm/testing/PythonShellMetricsBolt.java#L22-L23>`__.
