12.04 Server setup & Temp Monitoring
Posted: September 8th, 2012, 8:55 am
Greetings:
I have been using the guide "Build A Media Server" found on this website to build a Ubuntu12.04 server. I have been having some troubles and would like request help as I go along if possible. With that said I will start on the first issue.
The first problem I am having is with the script for monitoring the cpu temp and autoshutdown. The script is found here http://www.havetheknowhow.com/scripts/CPUTempShutdown.txt . As the text of the script states that the output of "Sensors" is assumed to be -----. If it is different edit the required strings. I understand this and my output is different, But I seem to have something wrong as it always says it's overheat.
Here is the output of "SENSORS" on my machine.
temp1 should be my CPU I believe, a dual core Phenom. I also believe that AMD processors only output 1 temp for multicores.
Here is my CPUTempShutdown.sh file as I have edited it (Note some info as posted here was changed, ie user, email for security reasons.)
I did remove the two ".ge" entries in the "if [ ${newstr} $1 ] and if [ ${newstr} $2 ] strings as I was getting a warning about them when I ran the script. Any help or advice on how to edit the script or fix the problem would be helpful.
Thank you!

# AUTHOR: feedback[AT]HaveTheKnowHow[DOT]com
# Expects two arguments:
# 1. Warning temperature
# 2. Critical shutdown temperature
# eg. using ./CPUTempShutdown.sh 30 40
# will warn when temperature of one or more cores hit 30degrees and shutdown when either hits 40degrees.
# NOTES:
# Change the strings ">>/home/htkh" as required
# Substitute string "myemail@myaddress.com" with your own email address in the string which starts "/usr/sbin/ssmtp myemail@myaddress.com"
# Assumes output from sensors command is as follows:
