Thanks!  Here is the script: (if the format gets messed up, I also attached
a file with the same contents)
---------------
#!/bin/sh

# Input parameters: Hostname, testname (column), and messagefile
HOSTNAME="$1"
TESTNAME="$2"
FNAME="$3"

if [ "$TESTNAME" = "license" ]
then
        # Analyze the message we got
        InUse=`grep "In Use" $FNAME | cut -d : -f 2 | sed "s/ //"`
        
        # The RRD dataset definitions
        echo "DS:license:GAUGE:600:0:U"
   
        # The filename
        echo "license.rrd"

        # The data
        echo "$InUse"

        # Added for debugging purposes
        if [ "$HOSTNAME" = "license" ]
        then
                echo $HOSTNAME, $TESTNAME, $FNAME >>license_test.txt
                echo "$InUse" >>license_test.txt
                cat $FNAME >>license_test.txt
        fi
fi


The output from the debugging part (license_test.txt) looks like this:
--------------
license, license, /usr/local/hobbit/server/tmp/rrd_msg_27159
8 
status license.license green Tue 05/10/2005- 7:37:41.18 
Pro/Engineer Wildfire 2 Licenses 
-------------------------------- 
Total licenses available: 31 
                  In Use: 8 


And here's the RRD definition:
--------------
[license]
        TITLE License Utilization
        YAXIS Used Licenses
        DEF:avg=license.rrd:license:AVERAGE
        LINE2:avg#@COLOR@:Used Licenses
        GPRINT:avg:LAST: \: %5.0lf (cur)
        GPRINT:avg:MAX: \: %5.0lf (max)
        GPRINT:avg:MIN: \: %5.0lf (min)
        GPRINT:avg:AVERAGE: \: %5.0lf (avg)\n


Two other hosts are sending license statuses and they're graphing fine.
Just this "license" hostname is not.  The graph shows up and the rrd file is
getting updated, but with no values.

Thanks again!!
