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

3. 添加pnp4nagios记录模板

4. 后续权限修补

1. 移除install.php文件

cd /usr/local/pnp4nagios/share
mv install.php install.php_bak

2. 添加悬浮tip

cp /opt/pnp4nagios-0.6.25/contrib/ssi/status-header.ssi /usr/local/nagios/share/ssi/

2. 修改php访问权限

sudo chown -R nagios.nagios /var/lib/php

3. 修复nagios权限

sudo chown -R nagios.nagios /usr/local/pnp4nagios
sudo chown -R nagios.nagios /usr/local/nagios

4. 修改pnp4nagios配置文件
   vim /etc/httpd/conf.d/pnp4nagios.conf

AuthUserFile /usr/local/nagios/etc/htpasswd #更改成nagios basic认证的密钥文件

5. 重启服务

service httpd restart
sevice nagios restart
