Unfortunately iostat doesn't report on st devices on all platforms
(certainly RH Linux, I believe also *BSD and HPUX)=20

You can get throughput by sampling bpdbjobs from the master.  An example
script attached, often worth running for a while with the output
redirected when tracking down performance problems.

If someone fancies modifying it to take account of multiplexing to give
total drive throughput that would be great.  It's not immediately
obvious to me how to determine from bpdbjobs the physical drive being
used in an SSO environment.

Sample output:
