HDD Health (S.M.A.R.T.) monitoring script

BSOD2600 · **Posted:** Sun Feb 20, 2005 2:13 pm

I wrote a script that takes the data output from HDD Health, a free S.M.A.R.T. monitor for Windows, and outputs it for Cacti. It reads the report file (ex: WDC WD740GD-75FLA1.txt)., which lists the names for the various attributes. Then it reads the data file (ex: WD-WMAKE1359731.hdd). for the updated attribute values. While the report file has values, you'll notice that the file is not updated until closure of the program.

The graphs are pretty boring (as they should be), but with the threshold addition being added into the next version of Cacti, it will play a vital role in monitoring a HD's health and possible failure prediction.

You'll notice the graph will have many values that are empty. This is perfectly normal. This happens because I added all of the SMART attributes from the various hard drive makers at my house. Some have values others don't.

One can add in additional values to be monitored. Just need to add it to the data input method, data templates and graph.

Does something like this exist for Linux based systems?

Sure http://smartmontools.sourceforge.net/

I could've written the script around this programs output, but it's commandline based and not as friendly as something GUI driven.

I would think commandline tools are more friendly to scripting than GUI tools.

Possibly. I still prefer to look at a GUI for the SMART values (and the various other things HDD Health shows) instead of Cacti or the raw text output in the command line.

It would be very nice to have smartmontools under Linux also working with cacti. Does somebody work on that and also want to share?

I guess its not possible, having one script for all different Harddisk types.
each OEM has an different S.M.A.R.T output. which means, you need a individual script for ex. MAXTOR, IBM, HITACHI, SAMSUNG and so on.

Onkel_Tom: That would require a compleatly different script. Since I'm not a linux user, this is not a priority for me.

sumsum: Why do you need seperate scripts? I added most of the common SMART values found in several brands of hard drives I have at my house. Heck, the available values still differ from model to model from the same company.

If you want to add more unique SMART values HDD Health reports, it's fairly easy. What are the other values you want to monitor that it currently does not?

BSOD2600 : sorry my fault i'm coming from the linux section

where I use smartmontools. it grabs all the information about the S.M.A.R.T Data, and those information differ from each OEM regarding the output report.

Having trouble importing the templates for some reason I am getting unmet dependancies...

How could I be screwing the import up... it seems pretty easy from your readme.

Looks like you already had the templates imported previously? Try deleting them (data template, graph template and data input methods) and try again. It wouldn't hurt to update your cacti version too to 0.8.6h + patches.

Upgraded to 0.8.6h +patches...

Deleted and re-imported but the same errors appear. The templates also create the data import methods that you specify in your readme. So those steps are not needed any longer?

BSOD2600 · **Posted:** Fri Jan 20, 2006 6:16 pm

Correct, they are not needed.

Not sure why that single Data Input Field in failing though. When you look at the Date template, are all the fields which appear in the sample graph present?

jengstro · **Joined:** Tue Nov 15, 2005 12:14 pm **Posts:** 156

Yeah. Everything looks ok (keeping in mind my limited knowledge of creating templates) once I have imported all the templates but just wondering why the errors even appear.

BSOD2600 · **Posted:** Fri Jan 20, 2006 6:29 pm

Possibly a cacti 0.8.6g or h bug? Not sure since I created this script/template almost a year ago.
