how to configure hardware temperature

[bravo444]

Hi, All,

I've just finished installation of FreeNAS 9.3. Now, I can see hardware monitors, but I would like to setup temperature of them. For instance, they are like CPU, hard disk temperature.
Is there something like configuration tool?

Thank you for your support!!

Regards,

I don't understand the question, can you reformulate please?

Hi,

Thanks for your mail. I mean, I just want to show hardware temperature on MRTG monitor also.
I need to add it by manual? (log into the system)

Regards,

I still don't understand fully what you want to do, sorry, but if it can help I've made a script to display the CPU and drives temperatures, see the link "Useful Scripts" in my signature if you're interested.

no problem.

let me ask you a question.

Do you need to check CPU, hard disk temperature on the system. If yes, you can check with these on FreeNAS web console as default?

 

[Bidule0hm]

You only need to check temps when you validate the thermal design of a new server, then they should stay pretty much the same. But yes, the only way I know to check the temps is to use the CLI.

When I set-up my FreeNAS box over a year ago, I found this script and put in a cron job so it would e-mail me the status every few hours. Hope it does the trick:

Code:

#! /bin/sh
echo "CPU temp :"
sysctl -a |egrep -E "cpu\.[0-9]+\.temp"
echo
echo "HDD temp :"
for i in $(sysctl -n kern.disks)
do
        DevTemp=`smartctl -a /dev/$i | awk '/Temperature_Celsius/{print $0}' | awk '{print $10 "C"}'`
        DevSerNum=`smartctl -a /dev/$i | awk '/Serial Number:/{print $0}' | awk '{print $3}'`
        DevName=`smartctl -a /dev/$i | awk '/Device Model:/{print $0}' | awk '{print $3}'`
        echo $i $DevTemp $DevSerNum $DevName
done

It will spit out something like this:

Code:

CPU temp :
dev.cpu.0.temperature: 47.0C
dev.cpu.1.temperature: 44.0C
dev.cpu.2.temperature: 43.0C
dev.cpu.3.temperature: 39.0C

HDD temp :
ada3 32C WD-WCC4Mxxxxxxx WDC
ada2 35C WD-WCC4Mxxxxxxx WDC
ada1 35C WD-WCC4Mxxxxxxx WDC
ada0 35C WD-WCC4Mxxxxxxx WDC
da1
da0

I found this buried away in a thread recently -- FreeNAS Temperature Report

I just wrote my own graphing setup and put it up on https://github.com/seren/freenas-temperature-graphing

 

[Bidule0hm]

Waow, great job ;)

I'll test that asap :D

That temp graph is great - is there an easy way to install it or is Dave's script to email temps easier to install?


For the next user:

Add Daves script @ 777 in the data store directory.

Add new cron job:

/bin/sh /mnt/Pool/temps.sh | sendmail -i richtj99@testcom

For servers not in a machine-room environment, I want temp monitoring and trigger levels for reporting (and shutdown) to avoid damaging the disks. The air-conditioning in the room could go out (or not be on yet, in the spring ), a fan in the case could fail, a drive could somehow fail producing high temperatures that might hurt adjacent drives, etc. So it's not just an initial setup problem to my way of thinking.

Meanwhile, I'm going to be using the script (or just the commands in it) to help validate some things during initial setup ;) .

Very cool. I'll try these as soon as I get access to my machine again.
Where do the graphs show up?
