How do I check (log files or commands) to see what data have 

been arriving at the server? Just want to trace to see what data are arriving and being stored in the rrd's. When I query, the rrd db data look incorrect.

on client, I'm sending custom data to the server:

$BB $BBDISP "data $MACHINE.vmstat2 green date

xvar xval yvar yval "

(Untested): In hobbitlaunch.cfg, add '--debug' or '--dbghost=[host]' to the launch parameters of hobbitd. See the manpage of hobbitd.
