  这里我们可以看到温度还没有相对应CPU,我们主要稍微修改一下/etc/sensors.conf就可以了,不过其实都不用我们自己去动手,一般我们都可以从主板生产商那里下载到配置文件。通过lmsensors我们就可以得到主板温度,CPU电压,风扇转速这些信息。我们可以根据这些数据来监察系统的运行情况来预防系统的问题。

  接下来让它和MRTG整合在一起吧

  [root@securitycn ~]# cd /usr/local/mrtg/bin

  [root@securitycn ~]# vi temp.sh

  #内容如下

  #!/bin/bash

  cputemp=`/usr/bin/sensors | grep temp1 |awk '{print $2}'|cut -c 2-4` #这句是说找出有temp1那一行,印出第二个列的2-4个字

  systemp =`/usr/bin/sensors | grep temp2 |awk '{print $2}'|cut -c 2-5` 不用解释了吧

  echo $cputemp

  echo $systemp

  # the uptime

  uptime | sed 's:^.* up (.*), [0-9][0-9]* users.*$:1:'

  # my name

  uname -n

  [root@securitycn ~]# chmod +x temp.sh 改成可执行

  [root@securitycn ~]# ./temp.sh 试试看有没有问题

  39

  33.5

  15:36:19 up 22:28, 1 user, load average: 0.04, 0.09, 0.04

  securitycn

  再来写下面的文件

  [root@securitycn ~]# cd ../etc/

  [root@securitycn ~]# vi temp.cfg

  WorkDir: /data1/usr/apache/htdocs/mrtg/temp/

  Target[index]: `/usr/local/mrtg/bin/temp.sh`

  MaxBytes[index]:80

  Options[index]: gauge, nopercent, growright

  YLegend[index]: Temp (度)

  ShortLegend[index]: 度

  LegendO[index]: 系统温度;

  LegendI[index]: CPU温度;

  Title[index]: 系统温度表

  PageTop[index]:

  主机温度表

  [root@securitycn ~]# /usr/local/mrtg/bin/mrtg /usr/local/mrtg/etc/temp.cfg

  执行3次就不报错了

  然后加入到crontab里面
