10. 修改 nagios 的配置文件: 打开performance_data
cd /etc/nagios
vim nagios.cfg


process_performance_data=1 
#将此变量值设为1 
host_perfdata_command=process-host-perfdata 
service_perfdata_command=process-service-perfdata 
#取消这两项的注释 






11. 修改 commands.cfg
cd /etc/nagios/objects
vim commands.cfg 


# 'process-host-perfdata' command definition 
define command{ 
       command_name   process-host-perfdata 
       command_line   /usr/local/pnp4nagios/libexec/process_perfdata.pl 
       } 
# 'process-service-perfdata' command definition 
define command{ 
       command_name   process-service-perfdata 
       command_line   /usr/local/pnp4nagios/libexec/process_perfdata.pl 
       } 
#添加上面两行在文件的末行 ，并删除或注释掉原有对process-host-perfdata和process-service-perfdata进行定义的字段 






12.添加小太阳模版，镶嵌在nagios页面上。
cd /etc/nagios/objects
vim templates.cfg
## 在最后添加
define host { 
name          host-pnp 
action_url    /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_ 
register   0 
} 
define service { 
name         srv-pnp 
action_url   /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=$SERVICEDESC$ 
register   0 
} 


#回到解压目录下，复制鼠标悬停图标显示，预览绘图所需的文件到nagios html目录
mkdir /usr/share/nagios/html/ssi/
cp ../pnp4nagios-0.6.14/contrib/ssi/*  /usr/share/nagios/html/ssi/


13. 检测配置文件语法
nagios -v /etc/nagios/nagios.cfg 




14. 重启服务
service nagios restart
