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.

I'm especially interested in how much data is being replicated from one
data center to another, to know how much of the available bandwidth is used.
Thanks,
