An rrd file with vmstat data is generated by default if the hobbit client is 
running on the relevant server. For disk IO, I think you want vmstat5, if you 
want a graph to appear with this information in the trends page, add 
something like this at the end of the line for the server in bb-hosts:

TRENDS:*,vmstat:vmstat|vmstat1|vmstat5

A quick way to see the graph is to click on the "CPU Utilization" graph on the 
trends page, and in the URL, change "service=vmstat" to "service=vmstat5".

You can use the pulldata option, after enabling the msgcache task on the 
client, in this case the hobbit server will connect to the client on port 
1984, where msgcache is running, and request the data the client last 
reported there (it connects to localhost ..).

I think you can only do it globally in the commandline options for bbnet. See 
the relevant man pages for details.
