SOLVED Measuring network bytes between replicants

[dpearcefl]

I have two FreeNas 9.3 boxes that provide replication between one box (master) and the other (slave). Because I'm going to be relocating the slave to another data center, I want to measure the amount of replication traffic in bytes between the two sites.

Any suggestions on how I might do this?

If the slave has no other traffic, or the replication occurs on a dedicated network, then on the slave you can use
netstat -I interface_name -b
to see cumulative bytes at any point in time.

Thanks, this worked as I needed it.
