Wim, I had not looked at /proc/diskstats before, but it returns the total number of reads, writes, etc, since system boot, so I would have to do some coding and remember previous values to get what we get from iostat. At this point I have things working ok so I don't feel the need to write another script.

No you wouldn't. Just use a COUNTER instead of a GAUGE and RRD will automatically track the previous value and show the difference.
