pfSense custom hardware not showing temperature sensors

techtester-m · Dec 3, 2019, 5:42 PM

Hi,

I installed a pfSense on mini-itx PC and set the settings to show the CPU temperature but it shows nothing and just stays on "updating..." forever.

Current install (AMD Ryzen 5 2400G):

Previous install (Intel i5-9600K):

Thank you,

What sensor type do you have selected in Sys > Adv > Misc ?

If it doesn't pass the values via ACPI you need the correct sensor driver. I'm not sure amdtemp supports that CPU yet though...

Try running: sysctl -a | grep temperature

@stephenw10 I tried both "AMD K8, K10, and K11, CPU on-die thermal sensor" and "None/ACPI" with rebooting after every change...nothing shows up in the dashboard. So you say this CPU isn't supported by the built-in drivers of pfSense?

@stephenw10 said in pfSense custom hardware not showing temperature sensors:

I executed it in Diagnostics > Command Prompt. Nothing shows up. Where exactly do I run commands like sysctl -a, unbound-control etc. ?

Yes you should be able to run it there. On the only AMD device I have, an APU I see:

hw.acpi.thermal.tz0.temperature: 55.1C
dev.cpu.1.temperature: 55.2C
dev.cpu.0.temperature: 55.2C

That's after setting the amdtemp driver. When I set that the system logs show:

Dec 4 17:47:08 	php-fpm 	63436 	/system_advanced_misc.php: Loading amdtemp thermal monitor module.
Dec 4 17:47:08 	kernel 		amdtemp0: <AMD CPU On-Die Thermal Sensors> on hostb4

So, yes, probably that CPU is not yet supported by the amdtemp driver in 2.4.4p3. You could try a 2.5 snapshot but just to get temps that seems extreme!
Check your BIOS settings, you may be able to have it pass values via ACPI which I would expect it to.

Ok...I will.

What do you mean "setting". Isn't that built-in to pfSense and enabled by default? Or you're talking about the dropbox selection in Sys > Adv > Misc?

stephenw10 · Dec 4, 2019, 6:01 PM

Yes, I'm talking that setting. Doing that loads the appropriate kernel module so it 'sees' the sensor device and creates sysctls that pfSense can then read.

@stephenw10 A little bit out of the scope of the original question but I've noticed that using the VPN I'm getting 10-20Mbps on that AMD CPU and on the Intel i5 I got almost full speed of 80+ Mbps. Same config/settings, AES-NI acceleration etc. The differences are that significant between these two when it comes to AES-NI encryption or maybe something is up with the VPN servers?

stephenw10 · Dec 4, 2019, 6:23 PM

Nope, you should easily get >100Mbps OpenVPN if the encryption load is the only limit. You are hitting something else there.

Steve

techtester-m · Dec 4, 2019, 7:32 PM

@stephenw10 Ok...I'll check that

techtester-m · Dec 5, 2019, 3:13 PM

@stephenw10 Damn! You're right. I just disabled the VPN and used my "raw" connection and speeds are the same...fing weird. The only possible explanations I could think of are ISP having problems and ISP slowing me down because I encrypted everything including DNS LOL but that could be paranoia.......If nothing changes until tomorrow I'm going to give these f**kers a serious call haha.....What do you think may be the problem. I'll do a quick clean install on another machine just to check for sure that this has nothing to do with my pfSense settings/config.

Edit: @stephenw10 That's really weird...I just finished a clean install on the previous Intel i5 PC and set the basic settings without using VPN or even changing the webGUI password etc. just the basic of the basic and I can't get more than 12 Mbps which is CRAZY!!! I'm definitely gonna have a talk with my ISP tomorrow...

stephenw10 · Dec 5, 2019, 3:13 PM

That sort of throttling I would make sure your links are all at the expected speeds/duplex and set to autoselect. If something there is hard set to 100Mb you might find the other end is running at 10Mb half duplex.
You would usually see a load of errors/collisions in Status > Interfaces if that happens though.

Steve

techtester-m · Dec 5, 2019, 4:43 PM

@stephenw10 No, that's the goddamn ISP, I talked to them today. I was planning on moving to another ISP anyway.
Thank you for your help,

Edit: All the links says "full-duplex" but for some reason only on the Realtek NIC it also says ",master" why would that be?

stephenw10 · Dec 5, 2019, 4:59 PM

Master indicates flow-control is active on the link. That's usually not a problem. Very rarely you might see one side doing something it shouldn't and sending flow control stop instructions incorrectly. Almost certainly not the case here though.

Steve

techtester-m · Dec 5, 2019, 5:09 PM

@stephenw10 And I can't change that anyway, it's a negotiation between that NIC and whoever, right?
Edit: Ok, I just read about Flow Control in the docs and if I see any problem with that NIC I'll disable it. But how do I edit this /boot/loader.conf.local file?

stephenw10 · Dec 5, 2019, 5:15 PM

Create that file if it doesn't exist. Then edit it with any text editor or from Diag > Edit File. You can create the file from there too by just specifying the path directly.

@stephenw10 Can you please answer this question too (an easy one I think), if you may :) - https://forum.netgate.com/topic/148689/getting-openvpn-warnings-in-the-logs

Thank you,

I googled and didn't find something useful, so can you please direct me a little bit about what I should search for in the bios in order to have the sensors pass data via ACPI? It's an MSI motherboard.

Also so this:

stephenw10 · Dec 5, 2019, 8:48 PM

First check the BIOS can see any temperature values. Usually they will display at least CPU temp, often some other thermal zones where sensors exist. If those are all enabled they are usually passed to the OS via ACPI but it maybe another crappy BIOS that has DSDT values tested, and marked as, Windows only. In which case just make sure you're on the latest BIOS.
Fixing that is almost certainly more effort that it's worth.

The last time this came up:
https://forum.netgate.com/topic/137205/temperature-readings
This is also Zen micro-architecture CPU so the same applies. It may require amdsmn which only appeared in FreeBSD 12.
