Python Script to Monitor Drive Temps

[Fox]

I have a python script that parses the SmartCtl output and essentially tokenizes its output (select fields) and prints all your drives and their drive temps automatically. I currently use it on FreeNAS and on my Windows box to have it automatically list all my drives and temps on demand. The intent was to store the data in a SQLite database and then graph them so i can monitor drive temps over time, but I never got that far. In fact, it could be used to also track other Smartctl data points as well.

In any case, if anyone wants it, I'm posting it below. It's python and really "simple" code to read. I should note that it was not tested on any other drives than my own, but should work out of the box. It works either from Windows (run it from a mapped or physical drive) and on FreeNAS command line.

Just didn't want the work to go to waste in case someone can use it. Note that it is based on a specific version of SmartCtl, so if SmartCtl is updated (majorly) and the output is changed, this script may not work. Currently, it is working on SmartCtl 6.2 (on my Windows Box).. Given the way SmartCtl was coded, I expect only a major redesign to change the output format.

Code:

import os,string

def Run_SmartCtl(strArgs):
    cmdstring = "smartctl " + strArgs
    the_output = os.popen(cmdstring).read()
    lines =str.splitlines(the_output)
    #lines = ["/dev/sda"]
    return lines
def Get_Device_Ids():
    lines = Run_SmartCtl("--scan")
    Device_List = []
    for line in lines:
        device_id = string.split(line," ",1)[0]
        Device_List.append(device_id)
    return Device_List
def Get_Device_Info(device_id):
    dev = DeviceRecord()
    dev_info_lines = Run_SmartCtl("-i " + device_id )
    bEnteredInfoSection = False
    dev.device_id = device_id
    for line2 in dev_info_lines:
        if ( not bEnteredInfoSection ):
            TheFirstField = string.split(line2," ",2)
            #if (TheFirstField[0].lower() == 'smartctl' ):
            #    print "SmartCtl Version is: " + TheFirstField[1]
            if ( line2.lower()  == "=== start of information section ===" ) :
                bEnteredInfoSection = True
        else:

Darn it, I was hoping this was a rickroll that wiped the unsuspecting user's hard drives.

I'm sure one of the citizens of your glorious nation could arrange that for you if you "ask" them.

No.. Sorry to disappoint, it only plays Rick Astley's "Never Gonna Give You Up". (And yes, I'm kidding)....

 

[cyberjock]

Here's my opinion of the situation.

Thanks for sharing your script, Fox. I expanded the functions to retrieve all current values from smartctl -a output. Overall the script only emails SMART drive temps and error status (I know this is redundant but I prefer to receive an email even when things are ok), but the function supports most of the standard SMART data so one could adapt it to do more, such as storing in a database as Fox suggested. I do realize that it's not as concise and simple as it could be but it works so I'm moving on. I basically just wanted something to monitor drive temps over time and also warn me of any dangerous temperature conditions.

I tested the script quite a bit but if anyone finds a bug please let me know. I plan on building on this code some day so please excuse all my commented out debug probes. In case you were wondering: the odd method of setting writestring = blah followed by file.write(writestring) will hopefully make it easier to update later for Python 3, which supports printing to files (avoiding annoying carriage return and other formatting hassles), which will make it much easier to flip back and forth to printing in the console window and printing to sendmail.

Note: Written and tested in FreeNAS 9.2.1.7 x64.

EDIT: You may notice that I put some crude warning messages in the email alerts, to warn in the event of a hard drive having SMART errors. As it is currently written (as of 11/21/14), it will not throw an error if the drive simply dies such that it does not respond to SMART requests. FreeNAS will through its own security/file system change warning emails, kind of, but this isn't a complete feature of the script and eventually I'll fix it. When I do, i'll be moving it to Github and post it in this thread.

Cool.. Thanks for sharing it.. I will try it when I get a chance, though given my schedule, I am not sure when that will be..

Hi, just to mess around. Couple of weeks ago i found this script in a sourceforge project, it reads the sysctl output and prints it in a fixed ip. Ends up looking like this:

http://sourceforge.net/projects/freenas-tempreport/

Great work,
anyway of getting this into a graph on the "reporting" page ?

 

[Ryan Allen]

I would love to see a graph! Good work everybody! I’m going to try this tonight!

 

[Plato]

Let's wake up the thread. I'd also like to see this on a graph. Any way to append this to the report pages on FreeNas?

 

[Ericloewe]

Great work,
anyway of getting this into a graph on the "reporting" page ?

I believe there is a ticket for that, which would probably be scheduled for 11.2.
