No problem, except I don't understand why the Wiki claims that it is
necessary to remove the '.' from the numbers. It seems this is to
convert the data to percentages, but that can be done in the graph
definition:
The cpu_pc and cpu_ec has always a "." in it:
kthr    memory              page              faults              cpu

pc has always 2 numbers after the "." and ec 1 (I hope this stays the same for next AIX releases).  Rrd wants integers (I think), so you have to strip the "." from the numbers.
And, indeed, the -b 1024 is a copy-and-paste error.

I have more AIX updates (iostat graphs), but I don't have the time to create patches, maybe at the end of this week.  After that I'm 2 weeks on holiday.
