Dashboard Widget for harddrive SMART status

mkirbst

hey,

i've put togehter a dashboard widget that shows the SMART status of the drives installed in the system. i hacked it together mainly from the code of the wake on lan widget and it looks like it work for me at the moment. but i think its a good idea if some people look over the code :)


require_once("guiconfig.inc");
require_once("pfsense-utils.inc");
require_once("functions.inc");
$devs = array();
?>

		echo '';
		echo '';
		echo '';
		?>

// Get all AD* and DA* (IDE and SCSI) devices currently installed and st$
exec("ls /dev | grep '^[ad][da][0-9]\{1,2\}$'", $devs);

if(count($devs) > 0)  {
	foreach($devs as $dev)  {

		$dev_state =  exec("smartctl -a /dev/$dev | grep result: | awk '{print $6}'");
		$dev_ident =  exec("diskinfo -v /dev/$dev | grep ident | awk '{print $1}'");
		##erste Spalte: Drives ausgeben
		echo '' . "\n";

		##zweite Spalte 
		echo '' . "\n";

		##dritte Spalte: smartstatus ausgeben
		echo '' . "\n"; #tabellenspalte

	}
}
?>

		  **<center>' . gettext("Drive") . '</center>**  |  **<center>' . gettext("Ident") . '</center>**  |  **<center>' . gettext("SMART Status") . '</center>**  |			
| ';
		echo '/dev/'. $dev ;
		echo ' | 

<center>' . "\n";
		echo $dev_ident ;
		echo '</center>

 | '; #tabellenspalte

		if($dev_state == "PASSED") 
			echo "$dev_state
"; ##gruener Hintergrund bei PASSED
		else
			echo "$dev_state
"; ##roter Hintergrund sonst
		echo ' |

If you want to use the widget, create a new file with the editor of your choice /usr/local/www/widgets/widgets/smart.widget.php and paste the code above in. But again, its a quick and dirty piece of code, use at your own risk!

i have tried to clean up the code, minor changes are:

(i hope) code is now more easy to read (but remains horrible :) ) if somebody want to modify it to his needs
copyright added (i hope its ok in this manner ?)
in the 3. column the SMART state is alligned centered now
the code of the widget consists now of exact 42 lines :)

@ jimp: thank you for commiting to git. :)

Thanks Marcel
I just made a couple of changes, to match the pfSense dashboard colors scheme:


"PASSED", draw background lightgreen --> 90EE90

any other SMART state, draw background lightcoral --> F08080

If anyone is interested, can download the smart.widget.php (ready to use) from: http://ptt.4mg.com/pfSense/

EDIT: File Reuploaded to include the Changes made by Jimp
