That makes two of us!

The serverside or client?  heck, here's both.

On the server in server/ext:
- -----
hobbit at randomaccess ~/server/ext $ cat cputemp.sh
#!/bin/sh
# Input parameters: Hostname, testname (column), and messagefile
#

echo `date` >/tmp/cputemp.runs

TMPLOG="/tmp/$1.$2.out"
echo "$1, $2, $3" > $TMPLOG
cat $3 >> $TMPLOG

HOSTNAME="$1"
TESTNAME="$2"
FNAME="$3"

# Check the test name so that this script can service multiple
# data collection needs
# if [ "$TESTNAME" = "cputemp" ]
# then

   # set up the Data Set, testname, and what kind:size:min:max
   # U means Unknown max.
   echo "DS:cputemp:GAUGE:600:0:U"

   # name the RRD for the host and test
   echo cputemp.rrd
   # Analyze the message we got.  If it's only one line, grab it.
   # The interesting number is the fourth element in this case.
   CPU=`grep CPU $FNAME | awk '{ print $4 }'`
   echo $CPU

exit 0
- -----


On the client in client/ext:
- -----
hobbit at currant:~/client/ext$ cat cputemp.sh
#!/bin/sh

COLUMN=cputemp
COLOR=green
MSG="Current CPU Temperature: "
host=`hostname`


cpu_temp=$( ipmitool sensor | awk -F\| 'NR==2{print $2}' | sed '/\..*$/
s///g' | sed '/^ */ s///g' )

# Converting to Fahrenheit.
temp=$((${cpu_temp}*9/5+32))

# Ok, we have the temp in degrees as an integer.
# Now to see if it's Very Bad.

if ((${temp} > 130))
        then
        COLOR=red
                MSG="${MSG} ${temp} degrees Fahrenheit!

                Hothothot!
                "
elif ((${temp} > 120))
        then
        COLOR=yellow
                MSG="${MSG} ${temp} degrees Fahrenheit.

                Getting Warmer...
                "
else
        MSG="${MSG} ${temp} degrees Fahrenheit.

        Chillin' like a Villain.
        "
fi

# Get this to the hobbit server
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR `date`

${MSG}
"
exit 0

That was my Cunning Plan, yah.
