布暑之前，请看我之前的快速安装布暑nagios文章。
都在监控服务器端安装配置：
图形依赖库
#yum install cairo pango zlib zlib-devel freetype freetype-devel gd gd-devel
rrdtools依赖 用来画图的
#yum install libart_lgpl rrdtool
pnp4nagios 主角，收集数据，展示图形
#yum install pnp4nagios
更改显示时间，不然会有8小时时差
#vi /etc/php.ini date.timezone = "Asia/Shanghai"
#vi /etc/pnp4nagios/config.php $conf['date_fmt'] = "Y.m.d H:i"; 更符合中国时间习惯
配置出图 由于pnp4nagios 0.6配置要用bulk+npcd模式,
官网说明 https://docs.pnp4nagios.org/pnp-0.6/config#bulk_mode
#vi /etc/nagios/nagios.cfg process_performance_data=1 host_perfdata_file=/var/spool/pnp4nagios/host-perfdata service_perfdata_file=/var/spool/pnp4nagios/service-perfdata host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHE CKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$ service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSER VICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATET YPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$ host_perfdata_file_mode=a service_perfdata_file_mode=a host_perfdata_file_processing_interval=15 service_perfdata_file_processing_interval=15 host_perfdata_file_processing_command=process-host-perfdata-file service_perfdata_file_processing_command=process-service-perfdata-file
修改command.cfg定义
#vi /etc/nagios/objects/command.cfg
# 'process-host-perfdata' command definition
define command{
command_name process-host-perfdata-file
command_line /usr/libexec/pnp4nagios/process_perfdata.pl --bulk=/var/lib/pnp4nagios/host-perfdata
}
# 'process-service-perfdata' command definition
define command{
command_name process-service-perfdata-file
command_line /usr/libexec/pnp4nagios/process_perfdata.pl --bulk=/var/lib/pnp4nagios/service-perfdata
}修改模板定义
#vi /etc/nagios/objects/templates.cfg
define host{
name host-pnp
action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_
register 0
}
define service{
name service-pnp
action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register 0
}修改主机，服务检测配置文件
#vi /etc/nagios/objects/hosts.cfg ... use linux-server,host-pnp //添加host-pnp模板 ... #vi /etc/nagios/objects/services.cfg ... use generic-service,service-pnp //添加service-pnp模板 ...
#nagios -v /etc/nagios/nagios.cfg 检测配置是否正确
#systemctl restart npcd #systemctl restart httpd #systemctl restart nagios
点击小图标，就可以打开图形监控页面了。
