写给自己 ：linux运维路，自己动手趟一遍

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

#yuminstallcairopangozlibzlib-develfreetypefreetype-develgdgd-devel

rrdtools依赖 用来画图的

#yuminstalllibart_lgplrrdtool

pnp4nagios 主角，收集数据，展示图形

#yuminstallpnp4nagios

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.dH: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_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'commanddefinition
definecommand{
command_nameprocess-host-perfdata-file
command_line/usr/libexec/pnp4nagios/process_perfdata.pl--bulk=/var/lib/pnp4nagios/host-perfdata
}
#'process-service-perfdata'commanddefinition
definecommand{
command_nameprocess-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
definehost{
namehost-pnp
action_url/pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_
register0
}
defineservice{
nameservice-pnp
action_url/pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register0
}

修改主机，服务检测配置文件

#vi/etc/nagios/objects/hosts.cfg
...
uselinux-server,host-pnp//添加host-pnp模板
...
#vi/etc/nagios/objects/services.cfg
...
usegeneric-service,service-pnp//添加service-pnp模板
...

#nagios-v/etc/nagios/nagios.cfg检测配置是否正确

#systemctlrestartnpcd
#systemctlrestarthttpd
#systemctlrestartnagios

点击小图标，就可以打开图形监控页面了。
