Hi Ron/Bernard,
Thanks for the suggestion Ron.
I had thought to do that (if I had no other option), but really wanted to
understand why the perfstat_cpu_total metrics had been selected, in preference
to those of perfstat_partition_total.
I am using Michael's v3.1.2 Aix RPM's (with much thanks), and can confirm that
they are also built using the perfstat_cpu_total system call.
Bernard, I've included the code mods (diff output below) that I see as
necessary to do this.
I've adjusted the code in an insular way, so as to not affect anything else
possibly relying on the returned data from the original perfstat_cpu_total call.
Note though that this patch should be assessed by someone like Michael prior to
adding it to your code base.
Does seem OK to me though. :-)

Very Best Regards to all.
