转自：http://hi.baidu.com/icanwen/item/e6ed673c3f79e7302f20c403
最近公司的机房空调经常的自动关闭！使机房温度过热引起设备故障！因而想到用nagios检测CPU温度！当温度达到一定上限时！自动发送SMS到手机。在dell R200测试通过。参照了网上 很多高手的资料在此谢过！
nagios 主程序服务服务定制设置如下：
define service{
use generic-service ; Name of service template to use
host_name fileserver
service_description cpu temperature
check_command check_nrpe!check_cpu_temp
}
被监控主机服务定制如下：
vi /usr/local/nagios/etc/nrpe.cfg
#解释：用sensors检测cpu的温度当cpu温度到达35度时报警，到达40度时处于紧急状态
command[check_cpu_temp]=/usr/local/nagios/libexec/check_cputemp.sh -m sensors -w 35 -c 40
不可以上传附件 插件代码直接贴到这里了：）
