trying to get netapp filer data into larrd graphs

[Tom Georgoulias <tgeorgoulias (at) nandomedia.com>]

I'm using the filerstats2bb script from deadcat.net to get from my
Netapp filers and displaying it in hobbit.  This is what is displayed on
the status page:

conn, cpu, disk, info, inode, qtree, trends, user_quota

The data displayed is accurate, but the only graph that works is conn.
The rest are severely broken.  I checked the rrd directory and the only
files that existed were:

memory.real.rrd
memory.swap.rrd
tcp.conn.rrd

Not sure why memory* exist at all, but they do and are empty.

I would like to fix this, starting with CPU.  I'm hoping that what I
learn here can be used when I attempt to create custom graphs for
user_quota & qtree with the custom RRD feature described in 
hobbitd_larrd.  The rest of this message concerns only the load 
average/CPU graph problem, since I figure this ought to work without any 
modification.

For example, this is the contents of a status summary displayed on the
CPU status page:
==
 Wed Feb 16 14:59:46 EST 2005 - CPU Utilization on
filerA.nandomedia.com is OK. Uptime: 63 days, 06:57:54.29, load=1

LOAD AVG on filerA.nandomedia.com is 1
==

Underneath the status message, a link for "hobbit graph la" instead of a 
real graph.

There is data in the usual places in hobbit/data/hist/

cat hobbit/data/hist/filerA,nandomedia,com.cpu

cat hobbit/data/hist/filerA.nandomedia.com | grep cpu
<snip>
cpu 1108128065 1108073455 54610 gr pu 1

cpu 1108385799 1108385495 304 gr pu 1

So why isn't the data being pulled from the status report messages and 
put into an rrd file to larrd can use it?
