What=92s the recommended way of measuring latency between nodes in a cluste=
r?

By that I=92m not referring to read/write latency for a given KS/CF.

Basically I want to inject a row in a node A and want to see how long it
takes to get to node B (assuming proper RF is set).


I have already some network monitoring in our windows environment between m=
y
distributed nodes in place. But I still would like to get a handle on how a
potential network and/or cassandra slowness affects inter-node latency.
Maybe there is a tool/cmd that I'm not aware of? Tx.
