　　注：要注释掉原有对process-service-perfdata和process-host-perfdata的定义

为主机添加小太阳图标
　　# vi /usr/local/nagios/etc/objects/yang.cfg
　　
define host {
use       linux-server
host_name    yang
address      192.168.1.10
action_url /pnp4nagios/graph?host=$HOSTNAME$
}
　　:wq
　　为单个服务添加小太阳图标
　　# vi /usr/local/nagios/etc/objects/yang.cfg
　　define service {
use        generic-service
host_name   yang
service_description      check_load
check_command       check_nrpe!check_load
normal_check_interval     2
action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
　　}
　　:wq
　　
重启 nagios 服务
　　# /etc/init.d/nagios restart
　　
# vi /usr/local/php/etc/php.ini
　　
magic_quotes_gpc = off (原为magic_quotes_gpc = on)
　　:wq
　　# service httpd restart
　　
# mv /usr/local/pnp4nagios/share/install.php  /usr/local/pnp4nagios/share/install2.php   (或者直接删除)
　　注：点击小太阳图标后会出现个测试页面，各项要求都PASS了，会提示你重命名或删除install.php文件，原因不详
　　
# ls /usr/local/pnp4nagios/var/perfdata  (看下面有没有nagios中定义的主机名目录以及目录下面有没有对应服务的rrd文件和xml文件)
　　注：nagio图像（pnp4nagios）只能显示nagios插件中的服务，以脚本监控的服务不显示图像
