hi,
Last month I had no time to add some unit tests, so it was delay. And I
found the storm-incubating 0.9.2 has changed the multilang implements.
So next week I will change code to compatible with storm-incubating 0.9.2,
and add some unit tests. Then I will reply this mail to ask for review.
Thanks

> Proposal for Multilang's Metrics feature

> Storm 0.9.0.1 exposes a metrics interface to report summary statistics across

> b) then update the metric in Python bolt process through RPC call.
> 2. In Metrics API:
> a) extend IMetric interface add a method for RPC call：public void
> updateMetricFromRPC(List<Object> params);
> b) modify IMetric implements, to support updateMetricFromRPC;
> 3. In ShellBolt，
> a) we have a Map<String, IMetric> to hold user's registered metrics
> object；
> b) we have a method registerMetric(String name, T metric) for user to
> register their metris object;
> c) we have a method handleMetrics(Map action) to handle RPC call from
> Python process；
> 4) In Multilang protocol: add a command "metrics" for shell process to make
> RPC call. The protocol is: {"command":"metrics",
> "name":"metric-registerd-name", "params":["param-1", param-2]}
> 5) In storm.py：add rpcMetrics(name, params), user can update remote metric
> through this RPC call.
