Debianにipmitoolを入れてmuninで監視

Dellサーバの温度測定のためにipmitoolを入れる。

apt-get install ipmitool

modconf で kernel/drivers/char/ipmi の ipmi_devintf と ipmi_si を組み込む。

/etc/rc.boot/ipmi

#!/bin/bash
mknod --mode=644 /dev/ipmi0 c `grep ipmi /proc/devices |awk '{print $1;}'` 0

/etc/munin/plugins/ipmi

#!/bin/bash

if [ "$1" = "autoconf" ]; then
        if [ -e /dev/ipmi0 ]; then
                echo yes
                exit 0
        else
                echo no
                exit 1
        fi
fi

if [ "$1" = "config" ]; then
        echo 'graph_title CPU Temperature'
        echo 'graph_args --base 1000 -l 0'
        echo 'graph_vlabel temperature'
        echo 'graph_category Temperature'
        echo 'graph_info This graph monitors the CPU temperature'
        echo 'cpu1.label cpu1 temp'
        echo 'cpu1.info cpu1 temperature'
        echo 'cpu2.label cpu2 temp'
        echo 'cpu2.info cpu2 temperature'
        exit 0
fi

/usr/bin/ipmitool -c sdr list full 2>/dev/null | awk -F , 'BEGIN {cpu=1;} /ESM CPU [0-9]/ {print "cpu" cpu ".value " $2; cpu++;}'

グラフ生成部分はもう少し真面目に書いた方がいい。
