Plugin for Monitoring CPU Temperature

[wreuel]

Hey guys,

I searched the web but not found, need a plugin to monitor the CPU temperature.
Does anyone have this plugin working?


Thank for your attention

If you set up the email report settings in FreeNAS, you can set your box to notify you by email if the temperature hits a threshold (defined by you), or if your box changes temperature by a certain amount (also set by you). I set it up using my Gmail account, it was super easy, and the results are perfect.

Brian, my email is set up, where I find the options to send over temperature?

 

[BrianDMG]

If you look down the left column (in the GUI) near the bottom is another S.M.A.R.T. (that isn't S.M.A.R.T. Tests) you can click on to configure, that's where you set the thresholds and input your email address.

 

[joeschmuck]

That is incorrect advice. That S.M.A.R.T. is also for hard drive monitoring, not CPU monitoring. Read the manual.

As for checking CPU temperatures, there is no plugin or GUI part you can add, it would need to be a CRON job or script to monitor CPU Temps. Do a search in the forums for cpu temperature and I'm sure if you look hard enough, it will pop out. Or type a google search for 'freebsd cpu temp' and that should get you on the right track.

I found this command:

Code:

sysctl -a | grep tempe

this is the right command? I'm not home, so I could not test.

 

[joeschmuck]

Yes, that is the command and will display all your CPU cores.

 

[wreuel]

Thank's joeschmuck, this code is work correctly...

ok now someone needs to setup a cron job to output this to a file, and then build a plugin to pull the data into a purdy graph

I vote you do it and then post the PBI for us. I mean it sounds so easy, right?

if I did it then the jail would somehow take over and turn into a windows NT domain

Something must've changed. This no longer works on FreeNAS-9.2.1.5. There is no more temperature under the dev.cpu nodes:

What did it used to say?

On a previous FreeNAS installation that I have (8.2.0), it says:

Note that there is a dev.cpu.0.temperature entry, while on 9.2.1.5 there is none.

I just checked mine and it's definitely there...

Note that alot of hardware doesn't report temperatures properly for FreeBSD to understand them(this is particularly so for AMD based and non-server grade motherboards).

What's your hardware?

 

[dlavigne]

Does loading the module referenced in http://www.unix-heaven.org/node/73 fix it?

What's your hardware?

It's an AMD Kaveri (A10-7700K) on an MSI A88XM-E45 motherboard.

 

[cyberjock]

Well, that's probably your answer unfortunately. :(

 

[George Kyriazis]

How do you know? Is there a plan for supporting it?

Thanks...

 

[cyberjock]

Well, the problem is that Intel provides a spec for monitoring temps and they have provided developers to handle that code. AMD is much less supportive of anything that isn't Windows. But, the fact that I said AMD as well as non-server boards are often a problem and your setup is both of those I think the answer is fairly likely.

So statistically your problem is probably related to owning AMD. I'm not sure how much more in-depth you can go though as it should be something that "works" or "doesn't work". AMDs seem to just have weird quirks. I've avoided AMDs for quite a few years now because Intel just flat out provides better software support for their hardware.

This isn't fanboy-ism or anything like that. 2 summers ago AMD laid off 1/2 of their developers that maintained open-source software like FreeBSD, Linux, etc. You can't do that kind of thing and expect quality to remain. And believe me, people have noticed.
