You can treat it like normal I/O device and collect information using iostat during high I/O/. You can also use tools like iozone.

You could look at the files in /sys/class/fc_host/hostX/statistics (where X is the number of your HBA), computing a rate from the absolute numbers. The number are in hex (0x...) for some obscure reason. This works for Emulex (lpfc) and Brocade (bfa) HBAs at least.
