centos7.3 快速安装布暑pnp4nagios图形显示

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

#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_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
