   command_name    process-service-perfdata
   command_line    /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl
   }
   define command {
   command_name    process-host-perfdata
   command_line    /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
   }

   chkconfig httpd on
   chkconfig nrpe on
   chkconfig npcd on
   chkconfig nagios on

10. 添加pnp4nagios记录模版
    修改/etc/nagios/objects/templates.cfg,添加如下内容

    define host {
            name       host-pnp
            action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$'class='tips'rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_
            register
            process_perf_data
    }
    
    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
            process_perf_data
    }

    templates.cfg Code

11. 在host和service定义中使用pnp4nagios模版
    编辑localhost.cfg文件，vi /etc/nagios/objects/localhost.cfg
    将use linux-server 修改为 use linux-server,host-pnp
    将use local-services修改为 use local-services,srv-pnp

    define host{
           use                    linux-server,hosts-pnp
           host_name              localhost
           alias                  localhost
           address                127.0.0.1
           }   
    
    define service{
           use                            local-service,srv-pnp
           host_name                      localhost
           service_description            PING
           check_command                   check_ping!100.0,%!500.0,%
           }  

    pnp services Code

    被监控机需要显示pnp按钮，修改vi /etc/nagios/objects/services.cfg
    将use local-services修改为 use local-services,srv-pnp

12. 出现的问题
    
    关闭 selinux
    setenforce 0
    sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
