Rob,

You are trying to combine two scripts into one.  Read the FAQ.

yeah found that with a grep rrdstatus, heh oops.

I seem to still be doing something wrong...

"Sir, I have no data."

Ok, so i did this

[cputemp]
        TITLE CPU Temp
        YAXIS Degrees Fahrenheit
        DEF:avg=cputemp.rrd:cputemp:AVERAGE
        AREA:cputemp#00CC00:CPU Temp Average
        -u 1.0
        GPRINT:cputemp:LAST: \: %5.11f (cur)
        GPRINT:cputemp:MAX: \: %5.1lf (max)
        GPRINT:cputemp:MIN: \: %5.1lf (min)
        GPRINT:cputemp:AVERAGE: \: %5.1lf (avg)\n

and this

GRAPHS="la,disk,inode,qtree,memory,users,cputemp,.....8<...

as well, on the server.
but what i get is a text link called

Status unchanged in 1 hours, 41 minutes
Status message received from 10.10.10.12 hobbit graph cputemp

that leads to nothing.  Not even a "nan" graph :P

I think maybe by echo is in the wrong place...?  Should it be before or
after the $BB msg command?  Does it matter?

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

umask 133

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

ipmitool sensor | grep Temp | awk -F\| '{print $1,$2,$3,$4}' >
$BBTMP/cputemp.$host

cpu_temp=`tail -n 4 $BBTMP/cputemp.$host |head -n 1 | awk '{print $2}'
|sed 's/\..*//g'`
# Converting to Fahrenheit.
temp=$((${cpu_temp}*9/5+32))

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

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

        Hothothot!
        "
else
        MSG="${MSG} $temp Degrees Fahrenheit

        Chillin' like a Villain.
        "
fi

echo "DS:cputemp:GAUGE:600:0:U"
echo "cputemp.rrd"
echo "$temp"

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

${MSG}
"

exit 0
