lm_sensors

lm_sensors は、マザーボード上の温度センサー等から温度、電圧、ファンの情報を取得する。

使い方

  • sensors を入力して、<Enter> するのみです。

仮想マシンの場合は、正常にハードが検出されないので注意が必要です。

lm_sensors セットアップ

  • インストール後、ハードを検出する為に対話形式で質問されるので、それに答えていく。
    特に、理由がなければ、デフォルトの応答(Enterキー押下)で良い思います。
[root@localhost]# sensors-detect
# sensors-detect revision 6170 (2013-05-20 21:25:22 +0200)
# Board: ASUSTeK Computer INC. P5LD2-Deluxe

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.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):		# ← [Enter] を押下

Some Super I/O chips contain embedded 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):			# ← [Enter] を押下
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               Yes
Found `Winbond W83627EHF/EF/EHG/EG Super IO Sensors'        Success!
    (address 0x290, driver `w83627ehf')
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no):							# ← [Enter] を押下
# DMI data unavailable, please consider installing dmidecode 2.7
# or later for better results.
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some hardware monitoring chips are 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):		# ← [Enter] を押下

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):		# ← [Enter] を押下
Using driver `i2c-i801' for device 0000:00:1f.3: Intel 82801G ICH7
Module i2c-dev loaded successfully.

Next adapter: nvkm-0000:05:00.0-0 (i2c-0)
Do you want to scan it? (yes/NO/selectively):				# ← [Enter] を押下

Next adapter: nvkm-0000:05:00.0-1 (i2c-1)
Do you want to scan it? (yes/NO/selectively):				# ← [Enter] を押下

Next adapter: nvkm-0000:05:00.0-2 (i2c-2)
Do you want to scan it? (yes/NO/selectively):				# ← [Enter] を押下

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `w83627ehf':
  * ISA bus, address 0x290
    Chip `Winbond W83627EHF/EF/EHG/EG Super IO Sensors' (confidence: 9)

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no):		# ← [Enter] を押下
Unloading i2c-dev... OK

[root@localhost]# sensors

以上で、インストール・セットアップは完了です。
