Monitoring HDD temperature

[UUVtQD]

Hi All!
I'm trying to monitor HDD temperature on my server.
In /etc/zabbix/zabbix_agentd.conf I add line

UserParameter=HDDTempSDA,hddtemp /dev/sda |cut -f3 -d":" |cut -f1 -d"°"|tr -d ' \011\015\032'

restart the zabbix-agent, try to test it and got this:

[root@alfa ~]# zabbix_agentd -t HDDTempSDA
HDDTempSDA                                    [t|25]

This means the UserParameter HDDTempSDA is working, isn't it?

So, I tried to add it to "Items":

Description:                     SDA HDD Temp
Type:                              Zabbix Agent
Key:                               HDDTempSDA
Type of information:          Numeric (float)
Units:                              C
Use multiplier:                  Do not Use
Update interval (in sec):     60
Flexible intervals (sec):	No flexible intervals
Keep history (in days):       90	  
Keep trends (in days):        365
Status:                            Active
Store value:                     As is
Applications:                    OS
Group:                            Linux servers

And press "Save" button.
But after pressing "Mass update" at the bottom of "Items" page the status of HDDTempSDA is displayed as "Not supported".
Why? What am I doing wrong?

Thanks in advance!
P.S. Both servers use CentOS 5.2

Ok,
i'm found error.
Log-file zabbix-agentd contains the following:

/dev/sda: open: Permission denied

How can I fix this?
Thanks in advance.

Looks like a permissions error. Try running hddtemp as a normal user (not root) and see if you get a permissions error. You might need to provide the full path, on my system it's /usr/sbin/hddtemp

Two ways to fix. One you can wrap sudo around this, and the other is to setuid root for hddtemp if it is not already.

Thanks for help!
"sudo" does not work - require "real tty" but the idea of "setuid" - is worked!
Thanks again for your help!
