[hobbit] Henrik -- some notes on AIX and the 4.3 do_vmstat.c

[Kauffman, Tom]

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 :-)

Take a look at

and
