    cgi.cfg 控制 CGI 访问的配置文件
nagios.cfg  Nagios 主配置文件
resource.cfg    变量定义文件，又称为资源文件，在此文件中定义变量，以便由其他配置文件引用，如$USER1$
objects objects 是一个目录，在此目录下有很多配置文件模板，用于定义 Nagios 对象
objects/commands.cfg    命令定义配置文件，其中定义的命令可以被其他配置文件引用
objects/contacts.cfg    定义联系人和联系人组的配置文件
objects/localhost.cfg   定义监控本地主机的配置文件

objects/timeperiods.cfg 定义 Nagios 监控时间段的配置文件
objects/windows.cfg 监控 Windows 主机的一个配置文件模板，默认没有启用此文件
备注: Nagios 在配置方面非常灵活，默认的配置文件并不是必需的。可以使用这些默认的配置文件，也可以创建自己的配置文件，然后在主配置文件 nagios.cfg 中引用即可。

    1.执行插件获得性能数据
2.调用性能数据的pl来进行解析
3.调用RRD来进行计算并最后写成XML

    1.在nagios.cfg中修改如下
    process\_performance\_data=1
    service_perfdata_command=process-service-perfdata
    host_perfdata_command=process-host-perfdata
2.定义命令
    define command {

           command_line    /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
    }

    1.执行插件获得性能数据
2.Nagios临时存储这些性能数据
3.Nagiospl来进行解析性能数据.性能数据从临时文件获取
4.调用RRD来进行计算并最后写成XML

    1.在nagios.cfg中修改如下
    process\_performance\_data=1

    service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
    service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$

    host_perfdata_file_mode=a
    host_perfdata_file_processing_interval=15
    host_perfdata_file_processing_command=process-host-perfdata-file

2.定义命令
    define command{
           command_name    process-service-perfdata-file
           command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/service-perfdata

    }

    1.执行插件获得性能数据
2.Nagios临时存储这些性能数据
3.Nagios将性能数据移动到临时文件夹中
4.NPCD扫描这个文件夹并且调用pl来进行解析性能数据.性能数据从临时文件获取
5.调用RRD来进行计算并最后写成XML

    1.在nagios.cfg中修改如下
    process\_performance\_data=1

    service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
    service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$
    service_perfdata_file_mode=a
    service_perfdata_file_processing_interval=15
    service_perfdata_file_processing_command=process-service-perfdata-file

    host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata
    host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$
    host_perfdata_file_mode=a
    host_perfdata_file_processing_interval=15
    host_perfdata_file_processing_command=process-host-perfdata-file

2.定义命令
    define command{
           command_name    process-service-perfdata-file
           command_line    /bin/mv /usr/local/pnp4nagios/var/service-perfdata /usr/local/pnp4nagios/var/spool/service-perfdata.$TIMET$
    }

    define command{
           command_name    process-host-perfdata-file
           command_line    /bin/mv /usr/local/pnp4nagios/var/host-perfdata /usr/local/pnp4nagios/var/spool/host-perfdata.$TIMET$
    }

    1.执行插件获得性能数据
2.npcdmod临时存储这些性能数据
3.npcdmod将性能数据移动到临时文件夹中
4.NPCD扫描这个文件夹并且调用pl来进行解析性能数据.性能数据从临时文件获取
5.调用RRD来进行计算并最后写成XML

    在nagios.cfg中修改如下
    process_performance_data=1
    broker_module=/usr/local/pnp4nagios/lib/npcdmod.o config_file=/usr/local/pnp4nagios/etc/npcd.cfg

    1.执行插件获得性能数据
2.mod_gearman将这些性能数据存储在队列内
3.pl通过gearman获取到性能数据,并且进行解析
4.调用RRD来进行计算并最后写成XML

    1.执行插件获得性能数据
2.ndo-mod自动将性能数据插入数据库
3.定制crontab计划.定期的调用ndo2pnp.pl文件.从数据库中读出需要的数据
4.再调用process_perfdata.pl.处理数据 生成XML

    Bulk Mode with NDO的部署比较简单.
1.确定NDO已经安装配置完毕.
2.复制process_ndo2pnp.sh,ndo2pnp.pl到nagios下的libexec/
3.确认process_ndo2pnp.sh内mysql的用户密码正确.
4.切换到nagios用户下,新建crontab任务:
    */1 * * * * /usr/local/nagios/libexec/process_ndo2pnp.sh 1&2>/dev/null
