Hardisk Temperature

[mandrk]

I try to monitor my hardisk temperature.
I put in /scripts the hddtemp.sh with content:
-----------
/usr/sbin/smartctl -a /dev/hda | grep -i temperature | awk '{printf $10}';
-----------
The output is:
----
root@mydomain /var/www/html/cacti/scripts> \ #./hdtemp.sh
44root@mydomain/var/www/html/cacti/scripts> \ #
-----
I create a Data Input Methods with Input Type: Scripts/Command
<path_cacti>/scripts/hdtemp.sh
I create a Data Template and Graph Template.
This 3 stepts is required for own script!
http://docs.cacti.net/node/200

i have grafic but with nan values
In logs i see:
06/30/2008 12:30:02 PM - CMDPHP: Poller[0] Host[1] DS[9] CMD: /var/www/html/cacti/scripts/hdtemp.sh, output: U
06/30/2008 12:30:02 PM - CMDPHP: Poller[0] Host[1] DS[9] WARNING: Result from CMD not valid. Partial Result:
-----------
Why output: U
other log looks like:
06/30/2008 12:30:02 PM - CMDPHP: Poller[0] Host[1] DS[4] CMD: perl /var/www/html/cacti/scripts/linux_memory.pl SwapFree:, output: 1048592

with values after output:
Like i say, if i run the script in command line i have output. A number
I try to put in Data Input Methods:
<path_cacti>/scripts/hdtemp.sh
/bin/bash /var/www/html/cacti/scripts/hdtemp.sh

I miss something .
I think most of configuration in ok but the script in not executed right

[streaker69]

try this:

Code: Select all

/usr/sbin/smartctl -a /dev/hda | grep -i temperature | awk '{printf $10"\n"}';

You could also make your script a little more dynamic by doing this:

Code: Select all

/usr/sbin/smartctl -a /dev/$1 | grep -i emperature | awk '{printf $10"\n"}';

then pass which device into the script:

./hddtemp.sh hdb1

or whatever.

Then when you configure your Data Input Query, you could set it up to ask the user which harddrive they want to query for temp.

I've also removed the 't' from Temperature, just in case some drives have it capitalized or not. After all, not many other words end in 'emperature'.

Same result!

You have in your first post that you named the file hddtemp.sh and in your log file it's listed as hdtemp.sh

Looks like a typo in your Data Input Query for the script.

No is ok!. In my first post i write hddtemp.sh. Is a misstype. The true filname is hdtemp.sh.

Step: 1
CREATE DATA INPUT METHODS
Input type : Script /Command
I use the <path_cacti>/scripts/hdtemp.sh Data Input Methods with 1 Output field named Input. I don't use input field yet ( you dynamic script must wait a lite bit . I must make this simple script to work.
Step2:
CREATE DATA TEMPLATE
I use the Data Input Method just created
Step3:
Create a Graph Template Items
Step4:
Make a grafic.
The grafic is maked after 1 cicle with nan value.
. wait for other some cicle...nan value

[streaker69]

did you chown the file to the user that runs cacti?

for example:

chown -R apache:apache hdtemp.sh

did you make the file executable?

chmod +x hdtemp.sh

[mandrk]

I give chmod 777
Yes make executable from first time with chmod +x hdtemp.sh

Diskfree runs without problem under root
Diskfree.sh returns me the:

hdtemp return some type of data
root@mydomain /var/www/html/cacti/scripts> \ #./hdtemp.sh

I try to put in hdtemp.sh
/usr/sbin/smartctl -a /dev/hda | grep -i temperature | awk '{printf "Input:"$10}' ;

That returns me value:
root@mydomain /var/www/html/cacti/scripts> \ #./hdtemp.sh
Input:43root@mydomain /var/www/html/cacti/scripts> \ #

Same result

[gandalf]

Please provide /full/path/to/grep and same for awk

[mandrk]

Please provide /full/path/to/grep and same for awk
Reinhard

Done!
replace my line with :
/usr/sbin/smartctl -a /dev/hda | /bin/grep -i temperature | /bin/awk '{printf $10}';

The result in command line is :
root@mydomain /var/www/html/cacti/scripts> \ #/usr/sbin/smartctl -a /dev/hda | /bin/grep -i temperature | /bin/awk '{printf $10}';
42root@mydomain /var/www/html/cacti/scripts> \ #

If i put print not printf the result is
root@mydomain /var/www/html/cacti/scripts> \ #/usr/sbin/smartctl -a /dev/hda | /bin/grep -i temperature | /bin/awk '{print $10}';
42
root@mydomain /var/www/html/cacti/scripts> \ #

The 42 value is printed to new line.
What is good choice for cacti
printf or print?

I don't now Perl to try the script in perl language

Diskfree runs without problem under root
...
I try to put in hdtemp.sh
/usr/sbin/smartctl -a /dev/hda | grep -i temperature | awk '{printf "Input:"$10}' ;

smartctl require root user. Cacti cron job is usually run under an apache or www-data user and can not use smartctl.

You need to configure sudo, or write a setuid wrapper.

I have the exact same script that he was working with yesterday running on my box, apparently it's running as apache, without any issues.

This is frightening.

streaker69, can you post the result of
ls -l /usr/sbin/smartctl /dev/hda
changing /dev/hda according to you system?

I have

Code: Select all

brw-rw---- 1 root disk   8, 0 2008-05-14 23:04 /dev/sda
-rwxr-xr-x 1 root root 157284 2006-09-29 15:50 /usr/sbin/smartctl

mandrk, can you identify under which user cacti cron job is running and try to execute it under this identity? Mine is running under www-data as specified in /etc/cron.d/cacti.

Code: Select all

su - www-data
cd /var/www/html/cacti/scripts
./hdtemp.sh

Did you look into /var/log/cacti/poller-error.log?

-rwxr-xr-x 1 root root 187224 May 24 12:42 /usr/sbin/smartctl

I tested his script out against my second HD in this machine, as the first HD doesn't report Temp.

Your second HD is labelled /dev/hdb and not /dev/hdb1

Either one returns the same values.
