Graphing revisited

[Rich Smrcina <rsmrcina (at) wi.rr.com>]

I've read the archived messages, the man pages and the doc and I still 
can not seem to get this right.

I have an external test that sends a message to Hobbit, something like this:

status vm1.sp_util green 21 Oct 2005 06:28:31 Spool Utilization 16 %

(this is what is sent by the external script, is there a way to see what 
is actually received?)

I've modified the 'extra.sh' script to check for this test:

if [ "$TESTNAME" = "sp_util" ]
then
        # Analyze Spool Utilization message
        SP_UTIL=`grep "Spool Utilization" $FNAME | awk '{print $10}'`

        # The RRD dataset definitions
        echo "DS:sp_util:GAUGE:600:0:100"

        # The filename
        echo "sp_util.rrd"

        # The data
        echo "$SP_UTIL"
fi

I've added 'sp_util' to the --extra-tests option in the rrdstatus 
section of hobbitlaunch.cfg

I've added this section to hobbitgraph.cfg:

[sp_util]
        TITLE Spool Utilization
        YAXIS Spool Utilization
        DEF:avg=sp_util.rrd:sp_util:AVERAGE
        CDEF:sp_util=avg,100,/
        AREA:SP_UTIL#00CC00:Spool Utilization
        -u 1.0
        GPRINT:sp_util:LAST: \: %3.0lf (cur)
        GPRINT:sp_util:MAX: \: %3.0lf (max)
        GPRINT:sp_util:MIN: \: %3.0lf (min)
        GPRINT:sp_util:AVERAGE: \: %3.0lf (avg)\n

An rrd file is being created and a link is being put on the status web 
page, but no graph is being displayed.  Just the text 'hobbit graph 
sp_util', which is the alt tag in the img definition.

This leads me to believe that there is something wrong with the graph 
image itself.

Are all of these steps correct, where did I go wrong?

Thanks.
