[hobbit] Re: Custom RRD graphs

[Rich Smrcina]

Brilliant detective work Dan.  I am trying something similar, but 
haven't had the good luck that you enjoy.

Here is the status message being produced for a column called pg_util 
(Page Utilization):

status vm1.pg_util green 12 Nov 2005 10:55:57  Page Utilization  OK
pg_util : 1

TEST2RRD contains 'pg_util=ncv' (it's not at the end, does it need to 
be?) and

NCV_pg_util="pg_util:GAUGE"

I've disabled the code in the extra script for this test and removed it 
from the --extra-tests list.  I've verified with ps that hobbitd_channel 
and hobbitd_larrd aren't using them anymore.  I still have a custom 
graph defined for this test, is that allowed using NCV or doesn't it care?
