lm_sensors

[asparak]

Hi Excito techies,

I don't particularly wanna go hacking around in the kernel source unless I have to, so I'll ask first. Do you have the i2C modules configured in the kernel, so that lm_sensors will work? In the 1.2.0 release, sensors-detect is unable to identify the bus properly

Enterprise:~# sensors-detect
# sensors-detect revision 4171 (2006-09-24 03:37:01 -0700)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no): y
Probing for PCI bus adapters...
Sorry, no known PCI bus adapters found.

We will now try to load each adapter module in turn.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.

Next adapter: MPC adapter
Do you want to scan it? (YES/no/selectively): y
Client found at address 0x6f
Handled by driver `rtc-isl1208' (already loaded), chip type `isl1208'
(note: this is probably NOT a sensor chip!)

Next adapter: MPC adapter
Do you want to scan it? (YES/no/selectively): y

Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!
Do you want to scan the ISA I/O ports? (YES/no): y
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM78-J' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Probing for `Winbond W83627HF' at 0x290... No
Probing for `Silicon Integrated Systems SIS5595'... No
Probing for `VIA VT82C686 Integrated Sensors'... No
Probing for `VIA VT8231 Integrated Sensors'... No
Probing for `AMD K8 thermal sensors'... No
Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No

Some Super I/O chips may also contain sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): y
Probing for Super-I/O at 0x2e/0x2f
Trying family `ITE'... No
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Fintek'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `ITE'... No
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Fintek'... No

Sorry, no sensors were detected.
Either your sensors are not supported, or they are connected to an
I2C or SMBus adapter that is not supported. See doc/FAQ,
doc/lm_sensors-FAQ.html or http://www.lm-sensors.org/wiki/FAQ
(FAQ #4.24.3) for further information.
If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.


Any guidance would be useful, so I can complete the task of getting cpu temp monitoring working, update phpsysinfo with it and finish a how-to for everyone else

Thanks

Hi asparak,

I don't know about the kernel issues, but I do know that our CPU doesn't have any internal temperature sensors. It isn't cosidered needed, since it is very low power (< 2W at full speed). There are other components (such as the SATA controller) that actually uses more power (hence, gets warmer).

The only internal temperature monitoring available is the disk temperature, which also is the only one really important.
