    I asked the same question on questions a day ago and for FreeBSD 4,
    Dan Nelson provided some patches for iostat to add the read/write stats:

    http://lists.freebsd.org/pipermail/freebsd-questions/2004-April/043644.html

    gstat does work for FreeBSD 5 but unfortunately it doesn't print
    simple text output that can be used to collect long term stats via a
    script...

    Thanks,
    Adi
