nagios 安装完了，只有数字输出监控内容是不是不炫丽呢?是不是想像CACTI 一样出炫丽的图呢？那你可以选择PNP，他可以满足你的需求，只要你的脚本符合perfdata规则，那么rrdtool就可以出数据，PNP就可以用图给你画出来。

1.下载安装 pnp4nagios-0.6.6.tar.gz

nagios $> wget http://cdnetworks-kr-1.dl.sourceforge.net/project/pnp4nagios/PNP-0.6/pnp4nagios-0.6.6.tar.gznagios $> apt-get install rrdtool librrds-perl
nagios $> tar zxvf  pnp4nagios-0.6.6.tar.gz
nagios $> cd pnp4nagios-0.6.6
nagios $> ./configure --with-nagios-user=nagios --with-nagios-group=nagcmd
nagios $> make all
nagios $> make install
nagios $> make install-webconf
nagios $> make install-config
nagios $> make install-init

2.创建配置文件

nagios $> cd /usr/local/pnp4nagios/etc
nagios $> mv misccommands.cfg-sample  misccommands.cfg
nagios $> mv nagios.cfg-sample  nagios.cfg
nagios $> mv npcd.cfg-sample npcd.cfg
nagios $> mv process_perfdata.cfg-sample  process_perfdata.cfg
nagios $> mv rra.cfg-sample rra.cfgnagios $>  cd pages
nagios $> mv web_traffic.cfg-sample web_traffic.cfgnagios $> cd ../check_commands
nagios $> mv check_all_local_disks.cfg-sample  check_all_local_disks.cfg
nagios $> mv check_nrpe.cfg-sample  check_nrpe.cfg
nagios $> mv check_nwstat.cfg-sample  check_nwstat.cfg

3. 重启服务

nagios $> /etc/init.d/npcd restart

4.修改 nagios 的配置文件.打开performance_data

nagios $> cd /usr/local/nagios/etc
nagios $> vim nagios.cfg
#打开注视项：
process_performance_data=1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata

5.修改 commands.cfg

nagios $> cd /usr/local/nagios/etc/objects
nagios $> vim commands.cfg
##添加
# 'process-host-perfdata' command definition
define command{command_name    process-host-perfdatacommand_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl}
# 'process-service-perfdata' command definition
define command{command_name    process-service-perfdatacommand_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl}

6. 添加小太阳模版，镶嵌在nagios页面上。

nagios $> vim templates.cfg
## 在最后添加
define host {
name       host-pnp
action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_
register   0
}
define service {
name       srv-pnp
action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register   0
}

7，修改 hosts.cfg 和  色services.cfg

nagios $> cd /usr/local/nagios/etc/eric.com
#修改hosts.cfg
nagios $> vim hosts.cfg
define host{use                     linux-server,host-pnp  host_name         eric.comalias                     eric.comaddress                 192.168.6.101}# 修改 services.cfg
define service{use                                     local-service,srv-pnp      host_name                       eric.comservice_description        PINGcheck_command            check_ping!100.0,20%!500.0,60%
}

8.重启 nagios 服务

nagios $> /etc/init.d/nagios restart
