Subject Re: How to measure data transfer between data centers?
Date Wed, 04 Dec 2013 17:08:39 GMT
https://wiki.apache.org/cassandra/Metrics has per node Streaming metrics 
that include total bytes/in out.  That is only a small bit of what you 
want though.

For total DC bandwidth it might be more straightforward to measure this 
at the router/switch/fancy-network-gear level.
