mrtg.cfg を mrtg.cfg.orgとしてコピーし、mrtg.cfg をEUC-JP化する

# cp /etc/mrtg.cfg /etc/mrtg.cfg.org

# nkf -e /etc/mrtg.cfg.org > /etc/mrtg.cfg


sensors.shと、hddtemp.shを"/root"に作成する。

# vi /root/sensors.sh


#!/bin/sh

sensors | grep Core | awk ‘{print $3}’ | sed -e ‘s/+//’ -e ‘s/[^0-9+.].*//’


# vi /root/hddtemp.sh

# chmod +x /root/sensors.sh /root/hddtemp.sh

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):
Module cpuid loaded successfully.
Silicon Integrated Systems SIS5595…                       No
VIA VT82C686 Integrated Sensors…                          No
VIA VT8231 Integrated Sensors…                            No
AMD K8 thermal sensors…                                   No
AMD Family 10h thermal sensors…                           No
AMD Family 11h thermal sensors…                           No
Intel digital thermal sensor…                             Success!
    (driver coretemp')
Intel AMB FB-DIMM thermal sensor...                         No
VIA C7 thermal sensor...                                    No
VIA Nano thermal sensor...                                  No

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):
Probing for Super-I/O at 0x2e/0x2f
Trying family
National Semiconductor’…                   No
Trying family SMSC'...                                     No
Trying family
VIA/Winbond/Nuvoton/Fintek’…               No
Trying family ITE'...                                      No
Probing for Super-I/O at 0x4e/0x4f
Trying family
National Semiconductor’…                   Yes
Found unknown chip with ID 0x8502

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):
Probing for National Semiconductor LM78' 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

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):
Using driver i2c-i801' for device 0000:00:1f.3: Intel ICH9
Module i2c-i801 loaded successfully.
Module i2c-dev loaded successfully.

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

Driver coretemp’:
  * Chip `Intel digital thermal sensor’ (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#—-cut here—-(ココが重要ポイントです。この部分を切り取り、”/etc/modules”に追記します。)
# Chip drivers
coretemp
#—-cut here—-

If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)

Unloading i2c-dev… OK
Unloading i2c-i801… OK
Unloading cpuid… OK


# vi /etc/modules


# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

lp

#—-cut here—-
# Chip drivers

# modprobe coretemp

# reboot (PC再起動。これは一応です。)

以上で、インストールと設定作業は終了です。このまま、5分以上待ってみて、グラフが正常に更新されていれば、おkということです。
お疲れ様でした!(^ω^)。
