Hi all im new to this site and new to Linux as well i got the courage up to build a server Ubuntu 12.04 in RAID 1 and i have all that working perfect samba file shares as well only cant get plex working file permissions id say but that's another story

I followed the guide of how to send emails i got the email working fine i can send emails from the command line in Ubuntu putty and it works fine
My problem is i folled the other guide monitoring DriveTempShutdown and CPUTempShutdown but I'm really lost in terms of the script that u download to edit for these 2 files
DriveTempShutdown CPUTempShutdown

this one of the files that i edited

#!/bin/bash

# PURPOSE: Script to check temperature of installed hard drives and report/shutdown if specified temperatures exceeded
#
# AUTHOR: feedback[AT]HaveTheKnowHow[DOT]com

# Expects three arguments:
# 1. Warning temperature
# 2. Critical shutdown temperature
# 3. If argument 3 is present then just check that drive letter
# eg. using ./DriveTemps.sh 35 45
# will warn when temperature of one or more drives reaches 35degrees and shutdown when any one of them hits 45
# eg. using ./DriveTemps.sh 35 45 c
# will warn when temperature of drive sdc reaches 35degrees and shutdown when it hits 45

# NOTES:
# Change the string ">>/home/htkh" as required
# Substitute string "scorpionvenomm@gmail.com" with your own email address in the string which starts "/usr/sbin/ssmtp scorpionvenomm@gmail.com"
# Change the command MyList='a b c d e' to the number of drives you have. In this case I'm using 2 drives

# Assumes /usr/sbin/smartctl -n standby -a /dev/sd$i returns the string 'Temperature_Celsius' somewhere

this file here

/usr/sbin/ssmtp scorpionvenomm@gmail.com </home/mark/MyScripts/msg.txt

i created a folder called msg.tx in command line and put this in


To: scorpionvenomm@gmail.com
From: scorpionvenomm@gmail.com
Subject: alert

The critical CPU temperature has been reached. The server is shutting itself down!

is that correct ?

same with DriveWarning.log i created a folder as well so the log would go in there but i get emails giving me errors heres the email i get

Sorry about the long message just thought id show it all and somebody might be able to help me i would really appreciate that

thanks

Hi,

The problem is because you have to edit the CPUTempShutdown.sh script to match the output from your CPU. Try calling the script from the command line and you'll see the "[: -ge: unary operator expected" error.

If you need help with that just shout!

Ian.

ok cool how do you do that sorry im new to linux ive been at this all day yesterday up till 2 am trying to figure out and back at it now :(


im looking at that error and ive gone back to the CPUTempShutdown.sh file and it says line 49 line 59 line 49 and line 49 thats the if statement i would not know how to fix that hopefully you can help me i would really appreciate that

hi just wondering does anyone know how to fix that script for me i would be really grateful as i keep getting emails every hour on the errors thanks

Hi,

Sorry for the delay. That script is not currently monitoring your CPU temps so it might be an idea to disable it until you've got it working.

Please issue the following command in a Terminal and send me the output in your next post:
Thanks,

Ian.

hey how are you thanks for getting back to me heres the code for sensors

Hi,

Change the line in the script which currently reads
to
If I've got that right it should pull out that your CPU cores are running at 24 and 26 respectively. If not, let me know.

Ian.

ok cool ive done that and heres the code thanks

What happens if you now run the script via the command line? Do you want to send me the output in your next post for me to have a look?

Thanks,

Ian.

is this what ur looking for ./CPUTempShutdown.sh 35 50 thats the ouptut when i do that
