Maybe, or I missed something when I wrote up that cookbook for you.
You did restart Hobbit after installing the new hobbitd_rrd and
hobbitd_client modules, I suppose?

It would probably help to get some debugging output from the 
hobbitd_rrd module. Do a "kill -USR2 <hobbitd_rrd PID>" and it will
start logging debugging output to the logfile. The next time your
Mac OS X client sends it's data, you should hopefully get some
info about what it tries to do. Repeat the kill-command to turn off
debugging.

(If you don't get anything in the hobbitd_rrd logfile, it's because the
client module doesnt send anything. So it fails to pickup the fact that
Mac OS X does have vmstat data now).

It will, it doesn't know anything about these numbers adding up to 100.
