    Since we're already introducing changes in Clojure, how would you feel about implementing
some (or all) of this in Clojure? I feel like MetricsState and Poller are bad fits for Java,
and that it could be a great place to use Clojure's concurrency features, such as an [agent](http://clojure.org/agents).

> This cmd line tool 'storm monitor' will use Nimbus.Client to get throughput information
from Nimbus Server.
> 1)One can specify topology's name, component's name to monitor it's throughput interactively.
> 2) It will statistics 'emit' and/or 'transferred' throughput in a given time window and
print it in a given time frequency
> The implementation will be much like yahoo's storm-perf-test (http://yahooeng.tumblr.com/post/64758709722/making-storm-fly-with-netty)
