Monitoring smartctl (smartmontools)

[llneoll]

Hellow,

I wrote a script to monitor some interesting values from the smartctl (smartmontools) output.

Please let me know if you find this usefull.

A detailed description will follow.

This is my first cacti graph. Feel free to give an advice.


INSTALL:
put this into /etc/sudoers:
CATI_USER_THE_POLLER_RUNS ALL= NOPASSWD: /usr/sbin/smartctl


1. copy the script smartcheck.php to smart/usr/share/cacti/site/scripts
(or whereiever your cacti installation path points to)

2. Import the Templates

3. Make a new Graph - choose Unix - smartmon XXX

4. Enter the device you want to monitor

3. Let me know if there are problems or if you where successfull

BTW: I was on the german "systems" (an exhibition) and found the cacti stand. Thanks for the inspiration!

Hey, a new user contibuting templates in about no time!
Thank you

It works only on localhost?

[Chaosratt]

Yea, only on localhost, no SNMP here since its just a php script parsing the output of smartctl.


Of note, the templates were a bit wacky at first, I had to insert some hard returns into them to make them sort nicely.
Also, for some reason my HDD returns the value "Power_On_Minuets" rather than "Power_On_hours" that this script/template expects.
Run smartmonctl -a <device> yourself to check. If that is the case then just open the script and temples and change every occurrence of "Hours" to "Minutes".
And for whatever reason my drive does not return a "Raw_Rear_Error_rate" value, so I just hacked that out of the graph template.


Woot for my first attempt at modifying graphs/templates/scripts!

Wow, thanks for the quick reply!
Thats exaktly what i have forgotten.

What did you sort exactly? The output of the Script? Can you send me the updated version?

Also, for some reason my HDD returns the value "Power_On_Minuets" rather than "Power_On_hours" that this script/template expects.

I have a disc that returns Power On Minutes too. But the most other return Power On hours.
You can also get trouble because not all harddisk vendors support the same Smart attributes.

BTW: if a Smartvalue in the Script is not detected, it will be defaulted to Zero.
So you have to check manually "smartctl --all" if your harddisk supports all values.

But i think the script can be easily adjusted.

I just modified the graph template a little bit after taking out the value that my drive did not report. For some reason all the values were jumbled together on the graph. I just added hard returns (<HR>) at the end of each one and they sorted properly.


I attached the modified template I use now.

Hi!
I run the script from the command line, all the SMART parameters are displayed correctly:

Code: Select all

$ opt/local/share/cacti/scripts/smartcheck.php /dev/disk0
Temperature_Celsius:47 Reallocated_Sector_Ct:0 Power_On_Hours:3465 Spin_Retry_Count:0 Seek_Error_Rate:0 Raw_Read_Error_Rate:0

But on the graph all options are to zero and in the log file all the values are zero:

Code: Select all

01/15/2010 10:35:13 AM - CMDPHP: Poller[0] DEVEL: SQL Exec: "insert into poller_output (local_data_id, rrd_name, time, output) values (385, '', '2010-01-15 10:35:01', 'Temperature_Celsius:0 Reallocated_Sector_Ct:0 Power_On_Hours:0 Spin_Retry_Count:0 Seek_Error_Rate:0 Raw_Read_Error_Rate:0')"

What do I wrong? Please help

As you see from the logs, the program isn't properly running and retrieving the data. Verify the permissions are correct.

Thanx for reply!
I have a few other PHP scripts and they are working properly. For example this:

Code: Select all

The permissions are exactly the same as that smartcheck.php
And on the recommendation, which is in the script-

Code: Select all

 * Don't forget to include cacti user in sudo!
 * include this into the /etc/sudoers file!!
 * For example: 
 *cactiuser  ALL= NOPASSWD: /usr/local/sbin/smartctl

I added this line to /etc/sudoers

Code: Select all

mihailartuhov  ALL= NOPASSWD: /usr/local/sbin/smartctl

It's my quote global.php:

Code: Select all

/* Default database settings*/
$database_type = "mysql";
$database_default = "cactidb";
$database_hostname = "localhost";
$database_username = "mihailartuhov";
$database_password = "amksoft";
$database_port = "3306";

As you see from the logs, the program isn't properly

I do not see in the log any errors even in the debuge mode, except that all values are 0

[BSOD2600]

Find in the cacti.log file with debugging enabled, when the smartctr script actually runs. What is the result / output?

There you have it. Script isn't returning values while run via the cacti poller.
