マザーボード ＆ CPU温度
本日一日の温度変化（五分間隔リアルタイム）マザーボードのセンサチップから各種データを取得するために
lm_sensors というツールを使用する
センサチップにより、取得できる各種データは限定されるため
現サーバとして稼働中の懐かしのM/B ASUS P3B-F を例に挙げる
[ lm_sensors のインストール ][root＠linux ~]# yum install lm_sensors
[ マザーボードのセンサチップを探り設定 ] (ずらっとデータが出てきたが全て [Enter] で切り抜けた)
[root＠linux ~]# sensors-detect
# sensors-detect revision 1.413 (2006/01/19 20:28:00)
This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.
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.
You do not need any special privileges for this.
Do you want to probe now? (YES/no):
← [ Enter ] ＝ Yes の意味〜〜〜

# Depending on your motherboard, you may have to use any of two formulae
# for temp2. Quoting Artur Gawryszczak (edited to reflect subsequent fixes
# to the driver):
# "I guess, that the formula "(@*15/43)+25, (@-25)*43/15" is correct
# for those Asus motherboards, which get CPU temperature from internal
# thermal diode (Pentium Coppermine, and above), while no formula is needed
# for Athlon/Duron boards, which use a thermistor in the socket."
# An alternative formula was then found and reported by Victor G. Marimon.
# See comments above if temp3 looks bad. What works for temp2 is likely
# to work for temp3 for dual-CPU boards, such as the CUV4X-D.
# Most Asus boards have temperatures settled like that:
label temp1 "M/B Temp"
label temp2 "CPU Temp"
# However, some boards have them swapped (A7N8X Deluxe rev.2,
# A7N8X-E Deluxe rev.2, A7N8X-X, CUV4X):
# label temp1 "CPU Temp"
# label temp2 "M/B Temp"
# Most boards have no temp3 by default, except for dual-CPU boards.
# label temp3 "CPU 2 Temp"
ignore temp3
