Everything is in the topic.
I would like to make a script to report all of this monitoring.

I've found the command
Code:
sysctl -a |egrep -E "cpu\.[0-9]+\.temp"
for CPU temp, but sysctl seems reporting wrong temperature (around 40°C).
I'm pretty sure that my CPU (i3 2100) is more than 40°C, being that it's fanless cooled (Thermalright HR-02)


For HDD temp i found the command
Code:
for i in $(sysctl -n kern.disks)
do printf "%s\t%s\t%s\n" $i $(smartctl -a /dev/$i | awk '/Serial Number/{x=$NF}$2~^Temperature/&&x{print $10"C",x}')
done

But it outputs an error that i can't solve :
Code:
awk: syntax error at source line 1
 context is
        /Serial >>>  Number/{x(NF)}$2~^ <<< Temperature/&&x{print $10"C",x}
awk: bailing out at source line 1
ada3


For mobo and GPU temp, didn't find anything.


Any help appreciated! :)

I rewrite it to more simple to understand :
Code:
#! /bin/sh

for i in $(sysctl -n kern.disks)
do
        DevTemp=`smartctl -a /dev/$i | awk '/Temperature_Celsius/{print $0}' | awk '{print $10 "C"}'`
        DevSerNum=`smartctl -a /dev/$i | awk '/Serial Number:/{print $0}' | awk '{print $3}'`
        DevName=`smartctl -a /dev/$i | awk '/Device Model:/{print $0}' | awk '{print $3}'`
        echo $i $DevTemp $DevSerNum $DevName
done

I got a i3-2100T using the default fan:
[root@freenas] ~# sysctl -a |egrep -E "cpu\.[0-9]+\.temp"
dev.cpu.0.temperature: 50.0C
dev.cpu.1.temperature: 50.0C
dev.cpu.2.temperature: 46.0C
dev.cpu.3.temperature: 46.0C

I got on "FreeNAS 8.0-RELEASE amd64"
freenas# sysctl -a | egrep -E "cpu\.[0-9]+\.temp"
dev.cpu.0.temperature: 39.0C
dev.cpu.1.temperature: 38.0C
____________________________________
But nothing on "FreeNAS 8.0.1-RELEASE amd64" because of :

/# sysctl dev.cpu.0.temperature
sysctl: unknown oid 'dev.cpu.0.temperature'
____________________________________
And got on FreeNAS-8.0.2-RELEASE-amd64 (8288)

[root@freenas] ~# sysctl -a | egrep -E "cpu\.[0-9]+\.temp"
dev.cpu.0.temperature: 42.0C
dev.cpu.1.temperature: 39.0C

Cluster, reviewing my topics to safekeep interesting stuff, i see your post and realize i must had skipped it at the time.
So, thanks it does work, but when i launch it, it takes a while before displaying the info for each disk, like if it made them work a lot... nevermind.

So my final script for system temps is
Code:
#! /bin/sh
echo "CPU temp :"
sysctl -a |egrep -E "cpu\.[0-9]+\.temp"
echo
echo "HDD temp :"
for i in $(sysctl -n kern.disks)
do
        DevTemp=`smartctl -a /dev/$i | awk '/Temperature_Celsius/{print $0}' | awk '{print $10 "C"}'`
        DevSerNum=`smartctl -a /dev/$i | awk '/Serial Number:/{print $0}' | awk '{print $3}'`
        DevName=`smartctl -a /dev/$i | awk '/Device Model:/{print $0}' | awk '{print $3}'`
        echo $i $DevTemp $DevSerNum $DevName
done


Returns :
Code:
CPU temp :
dev.cpu.0.temperature: 36.0C
dev.cpu.1.temperature: 36.0C
dev.cpu.2.temperature: 35.0C
dev.cpu.3.temperature: 35.0C

HDD temp :
ada7 26C S2H7J9AB807313 SAMSUNG
ada6 28C S2H7J9AB807309 SAMSUNG
ada5 28C S2H7J9AB807310 SAMSUNG
ada4 29C S2H7J1BB208475 SAMSUNG
ada3 37C 5XW1J1S1 ST32000542AS
ada2 39C 5XW1EXHR ST32000542AS
ada1 41C 5YD5RZNG ST2000DL003-9VT166
ada0 45C WD-WCAVY2756609 WDC
da0



First step is done.
Now, if you know a way to watch this temps and send an email alert if it reach thresholds... that would be the second step

FreeNAS CPU / Hard Drive Temperature Script

Nice Job djoole ... thanks for the inspiration.... I cleaned up the awk script in the for loop a bit so that it is only necessary to call smartctl once for each disk drive to save the unnecessary overhead.

Code:
#! /bin/bash
adastat () { echo -n `camcontrol cmd $1 -a "E5 00 00 00 00 00 00 00 00 00 00 00" -r - | awk '{print $10 " " ; }'` " " ; }
echo 
echo System Temperatures  - `date`
cat /etc/version.freenas
uptime | awk '{ print "\nSystem Load:",$8,$9,$10,"\n" }'
echo "CPU Temperature:"
sysctl -a | egrep -E "cpu\.[0-9]+\.temp"
echo
echo "Drive Activity Status"
for i in $(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if (match($i, '/ada/')) print $i }'); do    echo -n $i:; adastat $i; done; echo ; echo
echo "HDD Temperature:"
for i in $(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if (match($i, '/ada/')) print $i }') 
do
   echo $i `smartctl -a /dev/$i | awk '/Temperature_Celsius/{DevTemp=$10;} /Serial Number:/{DevSerNum=$3}; /Device Model:/{DevName=$3} END { print DevTemp,DevSerNum,DevName }'`
done
echo


I also included/changed the following:
  • a few cosmetic labels
  • included system load to correlate with the CPU termperature
  • list the system disks in ascending order (ada0-adaX)
  • omitted any disks other than adaX since they didn't apply on my system ( da0 = boot flash drive - no temp sensor).
  • +++show drive status (00=stopped, FF=spinning) prior to temperature reading to determine if disk was active (smartctl causes disk to start spinning)

+++ Credit for the drive spin down status belongs to the authors of this thread
http://forums.freenas.org/showthrea...ing-down-properly&highlight=camcontrol+cmd+-a

Hope someone finds this useful and can improve it some more.

your script wakes my HDDs up to check the Temp. So I add -n standby so it checks temp only the ones that are active

Modification of Monitor Script / Hard Drive Wake-up Now Optional

Good point arryo... I modified the script doesn't do that by default, script will now just say the temperature is unavailable and the drives stay idle. If you put a -w or -W option, it will cause the disks to wake up so you can get a snapshot of the resting temperature.

Code:
#! /bin/bash
#
#  Usage: lstemp [ -w or -W]
#  -w / -W: Wake up a sleeping drive to take it's temperature
#
adastat () { echo -n `camcontrol cmd $1 -a "E5 00 00 00 00 00 00 00 00 00 00 00" -r - | awk '{print $10 " " ; }'` " " ; }
echo 
echo System Temperatures  - `date`
cat /etc/version.freenas
uptime | awk '{ print "\nSystem Load:",$(NF-2),$(NF-1),$(NF),"\n" }'
echo "CPU Temperature:"
sysctl -a | egrep -E "cpu\.[0-9]+\.temp"
echo
echo "Drive Activity Status"
for i in $(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if (match($i, '/ada/')) print $i }'); do    echo -n $i:; adastat $i; done; echo ; echo
smartopt=`echo $@ | awk '{opt="-n standby"; if(match(tolower($0),'/-w/')) opt=""; print opt; }'`
echo "HDD Temperature:"
for i in $(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if (match($i, '/ada/')) print $i }') 
do
   echo $i `smartctl -a  $smartopt /dev/$i | awk 'BEGIN { DevName="N/A - Drive in standby mode" } /Temperature_Celsius/{DevTemp=$10;} /Serial Number:/{DevSerNum=$3}; /Device Model:/{DevName=$3} END { print DevTemp,DevSerNum,DevName }'`
done
echo

Interestingly enough, the script thinks that two of my drives always are in standby:
Code:
[root@kg-f3] ~# /mnt/zstore/home-tingo/bin/lstemp

System Temperatures - Tue May 22 21:42:53 CEST 2012
FreeNAS-8.0.4-RELEASE-p2-x64 (11367)

System Load: 0.00, 0.00, 0.00 

CPU Temperature:

Drive Activity Status
ada0:FF  ada1:FF  ada2:FF  ada3:FF  ada4:00  ada5:00  

HDD Temperature:
ada0 35 S2R8J9HB911201 SAMSUNG
ada1 36 S2R8J9HB911056 SAMSUNG
ada2 35 S2R8J9HB911213 SAMSUNG
ada3 36 S2R8J9HB904753 SAMSUNG
ada4 N/A - Drive in standby mode
ada5 N/A - Drive in standby mode

If I use '-w' it reports ok:
Code:
[root@kg-f3] ~# /mnt/zstore/home-tingo/bin/lstemp -w

System Temperatures - Tue May 22 21:45:28 CEST 2012
FreeNAS-8.0.4-RELEASE-p2-x64 (11367)

System Load: 0.00, 0.00, 0.00 

CPU Temperature:

Drive Activity Status
ada0:FF  ada1:FF  ada2:FF  ada3:FF  ada4:00  ada5:00  

HDD Temperature:
ada0 35 S2R8J9HB911201 SAMSUNG
ada1 36 S2R8J9HB911056 SAMSUNG
ada2 35 S2R8J9HB911213 SAMSUNG
ada3 36 S2R8J9HB904753 SAMSUNG
ada4 36 S2R8J9HB911216 SAMSUNG
ada5 35 S2R8J9HB911211 SAMSUNG

and if I repeat the 'lstemp' again, it still thinks ada4 and ad5 is standby (which isn't very likeley, since I have just talked to the drives, and all drives are part of a raidz:
Code:
[root@kg-f3] ~# zpool status
  pool: zstore
 state: ONLINE
 scrub: resilver completed after 2h32m with 0 errors on Mon May 21 01:15:45 2012
config:

	NAME        STATE     READ WRITE CKSUM
	zstore      ONLINE       0     0     0
	  raidz1    ONLINE       0     0     0
	    ada0p2  ONLINE       0     0     0
	    ada1p2  ONLINE       0     0     0
	    ada2p2  ONLINE       0     0     0
	    ada3p2  ONLINE       0     0     0  344G resilvered
	    ada4p2  ONLINE       0     0     0
	    ada5p2  ONLINE       0     0     0

errors: No known data errors

FWIW, this is FreeNAS-8.0.4-RELEASE-p2-x64 (11367).

Help Using camcontrol????

The problem has got to be with the camcontrol statement. Try typing this into a bash shell session:

Code:
adastat () { echo -n `camcontrol cmd $1 -a "E5 00 00 00 00 00 00 00 00 00 00 00" -r - | awk '{print $10 " " ; }'` " " ; }
echo `adastat ada4`


just to confirm that I'm right, but I'm sure the problem is with the camcontrol statement.

My best guess is that it has something to do with crossing the binary boundary from 3 to 4
but I don't understand what the control string does (just copied it) so I'm hoping
we have a hardware expert that understands camcontrol that can help out.

If you use the Google white paper on "Failure Trends in a Large Disk Drive Population" the best temperature for hard drive lifespan is 30 to 40C. 40-45C 3 year failure rates are about 11% and the >45C 3 year failure rates are about 12-20%!

The white paper is a good read if you are interested.

@MadMax: The script presented worked for me after changing the call to version from 'version.freenas' to just 'version' and some fiddling with spaces in the 'for' statements:

Code:
#! /bin/bash
adastat () { echo -n `camcontrol cmd $1 -a "E5 00 00 00 00 00 00 00 00 00 00 00" -r - | awk '{print $10 " " ; }'` " " ; }
echo 
echo System Temperatures  - `date`
cat /etc/version
uptime | awk '{ print "\nSystem Load:",$8,$9,$10,"\n" }'
echo "CPU Temperature:"
sysctl -a | egrep -E "cpu\.[0-9]+\.temp"
echo
echo "Drive Activity Status"
for i in $(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if(match($i, '/ada/')) print $i }' ); do    echo -n $i:; adastat $i; done; echo ; echo
echo "HDD Temperature:"
for i in $(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if(match($i, '/ada/')) print $i }' ) 
do
   echo $i `smartctl -a /dev/$i | awk '/Temperature_Celsius/{DevTemp=$10;} /Serial Number:/{DevSerNum=$3}; /Device Model:/{DevName=$3} END { print DevTemp,DevSerNum,DevName }'`
done

Your right. It works now both in 8.2 and 8.3.1. Thanks!


I used the esmart script and put this script together to send myself email of this information
Code:
#! /usr/local/bin/sh

(
echo "To: your email address "
echo "Subject: System Temperatures INFO"
echo " "
) > /var/cover


adastat () { echo -n `camcontrol cmd $1 -a "E5 00 00 00 00 00 00 00 00 00 00 00" -r - | awk '{print $10 " " ; }'` " " ; } >> /var/cover
echo
echo System Temperatures - `date` >> /var/cover
cat /etc/version >> /var/cover
uptime | awk '{ print "\nSystem Load:",$8,$9,$10,"\n" }' >> /var/cover
echo "CPU Temperature:" >> /var/cover
sysctl -a | egrep -E "cpu\.[0-9]+\.temp" >> /var/cover
echo
echo "Drive Activity Status" >> /var/cover
for i in $(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if(match($i, '/ada/')) print $i }' ); do echo -n $i:; adastat $i; done; echo ; echo >> /var/cover
echo "HDD Temperature:" >> /var/cover
for i in $(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if(match($i, '/ada/')) print $i }' )
do
echo $i `smartctl -a /dev/$i | awk '/Temperature_Celsius/{DevTemp=$10;} /Serial Number:/{DevSerNum=$3}; /Device Model:/{DevName=$3} END { print DevTemp,DevSerNum,DevName }'` >> /var/cover
done
echo

sendmail -t < /var/cover
exit 0


when I do run it though i get an echo of the hard letters. Not sure which echo is the cause of it and if I can turn if off from outputting. Otherwise the email is looks good.

Very useful script, thanks.

My only question (so far) is how to access the data for LSI/IBM-M1015 card's drives?

I have 10 3TB drives - 2 on the MB's SATA3 ports, and 8 on the M1015 card. Running the script shows only the two MB drives (ada0 and ada1). The 8 M1015 drives (da0-da7) are not shown.

The M1015 is flashed with LSI "IT" f/w.

Thanks, Karl

thats because of the ata filter

Code:
if(match($i, '/ada/')) print $i }'


we did this because normally "da" refers to the usb drive, which has no smart values ;)

Ah yes, I guess I should have read the script a little more carefully... :o It's been a looonnng time since I've played with awk, so I was a little lazy about it.

I can pull all 10 drive temps now.

Can't get drive act status off the LSI card, but I don't care as much about that.

Thanks!

do you mean the "Drive Activity Status",
if yes, sorry to shatter your dreams but there is a second ada filter xD
Code:
for i in $(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if(match($i, '/ada/')) print $i }' ); do    echo -n $i:; adastat $i; done; echo ; echo


Ok srly, this will call the "adastat" function which will call "camcontrol" for each found disk, you may want to check the output of this tool against you drives on the LSI
