Throughput counters for FC and SAS ports on a controller?

Maybe a silly question...

It's very easy - coming from a Cisco shop - to grab throughput and data statistics for things like physical ports or vlan interfaces on a cisco switch or router.  Is there an equivalent command to issue on a filer to get the same kind of data for an actual FC or SAS uplink on a head?

Just trying to gauge where I'm at with uplink utilization (whether or not I'm bottlenecking with too many shelves in a loop, etc).  Thanks in advance.

In advanced mode the stats counter hostadapter is available which shows FC and SAS port statistics. E.g.:

*> stats show -c hostadapter
