The AixPower5 is where I ended up, except that I'm not stripping the decimal point in do_vmstat.c. The vmstat_ec values look correct, but the rrd dump shows a value of zero for vmstat_pc instead of the expected 1.00000000e-02.
Time to play around a bit more; I'll add the decimal strip code and see what I get as a result.
Thanks for the pointer to the AIX tips -- I've got an Oracle DBA that will enjoy the memory graphs. I obviously need to spend more time looking around :-)

We're starting to move to the new IBM P6 environment, so I started looking at backing the 4.3 do_vmstat.c into 4.2.
This pretty well showed I'm not a C programmer.
However -- I added the two additional fields, cpu_ec and cpu_pc to the AIX structure in the 4.2 do_vmstat.c, recompiled, and the result works with the new P6 box. It will also work with new P5 or earlier systems, as the two extra values will just stay at <NAN> in the RRD. For existing older systems, I used 'rrdaddsource' from the RRD web site to add the cpu_pc and cpu_ec datasets to my existing RRD and everything is working just fine. Take a look at http://www.docum.org/twiki/bin/view/Hobbit/AixPower5 and http://www.docum.org/twiki/bin/view/Hobbit/AixTips if you are running hobbit client on aix.
