需要 rrtool 支持
yum install rrdtool gd gd-devel php-gd
(1)安装
#tar -zxvf php4nagios-*.tar.gz
#cd php4nagios
#./configure –with-nagios-user=nagios –with-nagios-group=nagios （如果单独编译安装的rrdtoool，则使用–with-rrdtool=/usr/local/rrdtool-1.2.xx/bin/rrdtool这样的形式）
#make all
#make install
#make install-webconf
#make install-config
#make install-init
#make fullinstall
(使用这条命令替换所有的make命令， make fullinstall)
#service httpd restart
(2)配置
pnp4nagios有5种模式，配置方法分别如下
pnp4nagios有5种模式，配置方法分别如下
- Synchronous Mode: (不讨论，参考官网https://docs.pnp4nagios.org/pnp-0.6/config)
- Bulk Mode:(不讨论，参考官网https://docs.pnp4nagios.org/pnp-0.6/config)
- Bulk Mode with NPCD：（我使用这种模式）
- Bulk Mode with NPCD and npcdmod(不讨论，参考官网https://docs.pnp4nagios.org/pnp-0.6/config)
- Gearman Mode(不讨论，参考官网https://docs.pnp4nagios.org/pnp-0.6/config)
- vim /usr/local/nagios/etc/nagios.cfg
- 修改内容
-
process_performance_data=0
为
process_performance_data=1
-
- 增加内容
# # service performance data # 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 performance data starting with Nagios 3.0 # 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
- 修改内容
- vim /usr/local/nagios/etc/objects/commands.cfg
增加command
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.$TIMET$ } - 启动npcd
/usr/local/pnp4nagios/bin/npcd -d -f /usr/local/pnp4nagios/etc/npcd.cfg
- 重启nagios
systemctl restart nagios - 检查数据文件是否存在
ls -la /usr/local/pnp4nagios/var/service-perfdata - 下载verify_pnp_config
wget http://verify.pnp4nagios.org/verify_pnp_config
- 检查pnp4nagios 在bulk+npcd模式下 是否配置正确

(3)集成到nagios的web页面中
- 在/usr/local/nagios/etc/objects/templates.cfg 模板中加入
define host{ name host-pnp register 0 action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_ } - 在被监控主机对应的cfg文件中，在define host use 一下模板中定于的 host-pnp 就会 在web上显示一个图表的标记
例如：vim /usr/local/nagios/etc/objects/oa_server.cfg
define host{ use windows-server,host-pnp; Inherit default values from a template， host-pnp 就是调用在templates.cfg 中定于的显示图像的功能 ... }
(4)配置apache
pnp4nagios4.10版本apache至此不需要做任何配置，直接就可以访问了，升级到0.6后发现必须rewrite了
安装pnp4nagios 时使用make install-webconf
这个会在/etc/httpd/ conf.d/中生成pnp4nagios.conf文件将其引入到/usr/local/apach2/conf/http.conf文件中
# 使用 pnp4nagios Include /etc/httpd/conf.d/pnp4nagios.conf
访问http://server_ip/pnp4nagios (所有红色的内容都要修正成绿色)
