Hi,

Will it be simpler to just measure = the network interface of the node instead?=A0

Hi Chris,
I think streaming is used for repair tasks, bulk loading and th= at kind of things, but not for regular replication traffic.

I think you're right that I should look into network tools. I don&= #39;t think cassandra can supply this information.

Thanks,
Tom

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

Is there a way to know how much data is transferred between two nodes, or more specifically, between two data centers?

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,
