Fascinating, I see something similar on my X11SSM-F (but less pronounced). My guess is that IPMI is using a separate thermistor placed close to the CPU socket, which will naturally lead to lower numbers than those measured at the die.

Seems plausible -- I'm using a C2550D4I, which can, apparently, have temp issues ... but a full 20.0C degrees seems like an awfully big difference.

Hats off to seren and everyone else.. even this newbie has the script up and running! Now I am trying to get the email portion working and while I can get it to partially work I am running into issues.. If I paste the script into the shell it will send me the cpu image, but its the same image over and over - not the most current one even though the png file in the script "folder" is current. It also says it cant find the drive .png file - even though its in there and the file name is identical. Am I missing something simple? Here is the script that I paste into the shell:

Code:
#!/bin/sh

### Parameters ###
email="X@gmail.com"
subject="NAS Temps"

	uuencode temps-2min-cpus.png temps-2min-cpus.png > /tmp/out.mail
	uuencode temps-2min-drives.png temps-2min-drives.png > /tmp/out.mail
		mail -s "${subject}" "${email}" < /tmp/out.mail


the output in the shell is this:
Code:
[root@freenas ~]# #!/bin/sh																										
[root@freenas ~]#																												 
[root@freenas ~]# ### Parameters ###																								
[root@freenas ~]# email="X@gmail.com"																						
[root@freenas ~]# subject="NAS Temps"																							 
[root@freenas ~]#																												 
[root@freenas ~]#	 uuencode temps-2min-cpus.png temps-2min-cpus.png >> /tmp/out.mail											
[root@freenas ~]#	 uuencode temps-2min-drives.png temps-2min-drives.png >> /tmp/out.mail										
uuencode: temps-2min-drives.png: No such file or directory																		 
[root@freenas ~]#		 mail -s "${subject}" "${email}" < /tmp/out.mail														 
[root@freenas ~]#	 


after I hit enter on the last line, the email sends with only the cpu file attached - although it is from 4 days ago when I first got the sctipt to work - also, eventhough both the cpu and drive .png files are shown in the directory and both are correct and accurate up to the minute, it doesnt like the drive file name.

any help is appreciated!

thanks

@JohnnyGrey i create a little script to send me the files:
Code:
#!/bin/sh

### Parameters ###
email="your_email@email.com"
subject="Subject name"

### Send config backup ###
	cp /mnt/sysVault/sysDataSet/bin/
	uuencode temps-1min-cpus.png temps-1min-cpus.png > /tmp/out.mail
	uuencode temps-1min-drives.png temps-1min-drives.png >> /tmp/out.mail
	uuencode temps-5min-cpus.png temps-5min-cpus.png >> /tmp/out.mail
	uuencode temps-5min-drives.png temps-5min-drives.png >> /tmp/out.mail
	mail -s "${subject}" "${email}" < /tmp/out.mail

so after some more digging and trial and error I can now run the script from the shell as long as I am in the proper directory.. in my case, /mnt/Camera/script and I figured out that /tmp/out.mail will only hold 1 image. So if I change the name it works for cpu temps as well.. still cant get the script to run properly however..

Ooh, pedantry! :D

Actually, it's degree Celsius. Celsius is capitalized because it is a degree, whereas proper SI units are not - like tesla or newton are lowercase, whereas degree Celsius and degree Fahrenheit have this sort of camelCase going on (though it should really be dromedaryCase, since there's only one hump).
I know it's one and a half years later, but I just have to set this straight ;)

The casing has nothing to do with degrees, it's actually based on whether the unit is named after a person. For example, Tesla and Newton are both upper case because they're named after, well, Tesla and Newton. So are Celsius and Fahrenheit, but not meter or gram, for example. Sorry for going off-topic, I'm gonna be silent now :D

I'm pretty sure that SI units are supposed to be lowercase when spelled out. It's the symbols that are uppercase for units named after people (hence N, T, Hz, Ω, A, V, etc., but kg, m, s, cd, etc.).

You're right, I knew about the symbols and thought it was the same with the names.

Is the script in the git repository compatible with FreeNAS 11 (old UI)? It says tested with 9.11 but not 11. Has anyone tried it? Any issues?

It should be. There's no 9.11, so I assume that's a typo for 11.

Yes. There is a typo …but it's mine. The repo says tested on 9.3 and 9.10.
:oops:

In any case, it should work.

Love this script. Using it on 11-u3. I've used it to tweak my fan speed to put my hard drives as optimally as I can centered between min and max. Currently, I'm droping the images to a volume with a simple HTML file that is accessable on a jail running a webserver. Makes it easy to view with a shortcut.

Is there any possibility of adding these images to the FreeNAS reporting tab?

Just discovered this script and installed it, but found that it doesn't log the temps from SAS drives. Data from smartctl is reported differently for these drives, so I needed to add a line to the awk script in rrd-lib.sh to parse the format:

Code:
BEGIN		 { attr=0; temp=-99 }
$1 ~ /Current/ { attr=$1; temp=$4}
$1 ~ /19[04]/ { if (attr != "194") { attr=$1; temp=$10 } }
END		   { if (temp != "-99") print temp }


This is my first time dealing with awk scripts, so there's probably a better regular expression to use (I couldn't get it to find the entire string for some reason). Here's an example from smartctl (up to where temperature is reported) of a drive I'm using:

Code:
smartctl 6.5 2016-05-07 r4318 [FreeBSD 11.1-STABLE amd64] (local build)

Or you could just look at the charts now baked into FreeNAS in 11.2 (you can try the beta and look at the disks report in the legacy GUI, or just wait for the final release).

The beta one isn't good idea.
will be waiting 11.2 release.
And can I install the hddtemp tool at the least, as under Linux OS?
Code:
pkg update
Updating local repository catalogue...
pkg: file:///usr/ports/packages/meta.txz: No such file or directory
repository local has no meta file, using default settings
pkg: file:///usr/ports/packages/packagesite.txz: No such file or directory
Unable to update repository local
Error updating repositories!

hddtemp looks like a great option if it can be compiled for FreeBSD/FreeNAS... I had learned about it over the weekend when looking into options to integrate my FreeNAS boxes into homeassistant. I will have a shot at doing that soon.

As far as I could tell by googling, there's no pkg for it already ported, so it will be a case of doing a git clone of the project and seeing if the gcc can handle what's there to compile it.

The 11.2 release will not be too long, but I would still like to have the hddtemp daemon for homeassistant.

In short, "tin"/hardcore) (about hdd monitoring). still have to wait for 11.2..

11.2 doesn't seem to have made it out yet, and I'm also unwilling to go beta on this system, but I'll look forward to it. Although I may have to continue my own system as well, because mostly I look at it combined with two other systems on a "dashboard" web page, and mostly I look at it from places that I don't want to give access to the real control GUI of the systems.

Hello,

I'm using the nice script made by @Seren here so I can monitor my HDDs drives temps on my server. I'm running on FreeNAS 11.2 stable.

I found out that a very convenient way for me to check the temps in my web browser is just to launch a little python server on any port like that:

Code:
cd scripts
python -m http.server 8014


So I just have to auto refresh url

Code:
http://myserverip:8014/temps-5min-drives.png


From any web browser and I can see my live temps.

Problem is it's really boring to launch those commands manually each time I need to check temps from one computer, so is there any way to automatize the process by launching the python server using Init/Shutdown Scripts?

I tried a few commands, still with no success. For example, this one is not working when setup in Init/Shutdown Scripts as a Post Init Command:

Code:
cd /root/scripts/ && python -m http.server 8014


Thanks for any helpful advice.
