Hi, I’m new to Apache S4 and I began using the s4.metrics.config parameter.

I’m currently running the Twitter Trending example and want to be able to see 
the time it takes to process each twit from the processing elements. I suppose 
that the file is 
org.apache.s4.example.twitter.TopicCountAndReportPE-pe-processing-time.csv

I just wanted to know if enabling the s4.metrics.config parameter in the first 
node will enable the metrics on the rest of the nodes that I start later or if 
I have to start each node with that parameter enabled.

Another question, is there a way of managing the metrics as a whole? 
Practically what I want to know if it is possible to see how many events are 
processed by second each time that I enable a node.

Thanks.
