Is there a compelling reason not to fold the above into one line:

    temp=`ipmitool sensor | tail -n 4 | head -n 1 | awk '{ print $3 }'`

Does this bit work??  I get:

    ./ipmi.sh: line 22: temp: command not found

and an empty file called '130'.  This works for me:

    if [ $temp -gt 130 ]
    then

The simplest way to graph it would be to have the message read something like:

    cpu temp : $temp

then follow the instructions in the "Custom Graphs" entry from the
Help dropdown.  You already have the first part - collecting the data.
If you use NCV, the above line would go into the RRD as cputemp,
because it takes everything before the colon and strips out spaces to
make the name, then takes the rest of the line as the number.  That
probably a gross over-simplification... :)
