I do get an IOSTAT column with this data in it but the graph at the bottom
has always been blank.

Lets see what data you're sending into the iostat handler. Could you do a
~hobbit/server/bin/bb 127.0.0.1 "hobbitdlog HOSTNAME.iostat" and show us the
outpu ?

If the iostat data is sent as "data" messages (i.e. you dont have an iostat
column), then you'll need to snoop the messages going out on the hobbit
data-channel: Login as the hobbit user, then run

   server/bin/bbcmd sh
   hobbitd_channel --channel=data cat |tee log |grep iostat

Wait for a while until an iostat message shows up, then pick it out of the
logfile.

Henrik
