为nagios装上pnp4nagios功能-创新互联

nagios的安装不再赘述，直接在nagios服务端进行安装pnp4nagios软件

安装展示图形页面pnpnagios（rrdtool工具用来存储数据并画图，pnpnagios用来展示图形数据）

参考：http://docs.pnp4nagios.org/pnp-0.6/install

http://docs.pnp4nagios.org/pnp-0.6

tar xf pnp4nagios-0.6.25.tar.gz

cd pnp4nagios-0.6.25

yum install rrdtool rrdtool-perl -y

./configure

编译报错:

checking for Perl Module Time::HiRes... no

configure: error: Perl Module Time::HiRes not available

解决办法：

yum -y install perl-Time-HiRes

再次编译

./configure

make all

make install

make install-webconf

make install-config

make install-init

make fullinstall

安装后出现如下输出：

由于nagios采用的是4.1.1，pnp4nagios采用的是0.6.25

在官方文档有好几种配置pnp4nagios的模式，但是采用sync的模式会一直收集不到数据，而报错，于是改用了Bulk Mode with NPCD，成功出图，这里分析配置过程：

参考：http://www.aboutmonitoring.com/installing-nagios-core-4-pnp4nagios-check_mk-nagvis-centos-7-redhat-7/

1、编辑nagios.cfg文件，修改

process_performance_data=0将这个值改为1

##### Values: 1 = process performance data, 0 = do not process performance data

enable_environment_macros=1

2、然后去掉下面两个注释，使之启用：

#host_perfdata_command=process-host-perfdata

#service_perfdata_command=process-service-perfdata

然后在nagios.cfg配置文件中加入以下：

# 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

各个文件的使用可以查看官方说明

3、修改commands.cfg

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.$TIMET$

}

然后开启npcd服务：

/usr/local/pnp4nagios/bin/npcd -d -f /usr/local/pnp4nagios/etc/npcd.cfg

4、

[root@RS1 libexec]# /etc/init.d/nagios checkconfig

Running configuration check...

 OK.

[root@RS1 libexec]# service httpd restart

停止 httpd：                        [确定]

正在启动 httpd：

[root@RS1 libexec]# /etc/init.d/nagios reload

Running configuration check...

Reloading nagios configuration...

done

5、浏览器访问

http://192.168.1.155/pnp4nagios/

出现报错：PHP GD extensionPHP GD extension not available

解决：

yum -y install php-gd

[root@RS1 libexec]# /etc/init.d/nagios checkconfig

Running configuration check...

 OK.

[root@RS1 libexec]# service httpd restart

停止 httpd：                        [确定]

正在启动 httpd：

[root@RS1 libexec]# /etc/init.d/nagios reload

Running configuration check...

Reloading nagios configuration...

done

再看观察浏览器报错：

Your environment passed all requirements. Remove or rename the /usr/local/pnp4nagios/share/install.php file now.

解决办法：

mv /usr/local/pnp4nagios/share/install.php /usr/local/pnp4nagios/share/install.php.ignore

以上只是解决了收集数据的功能，还必须在每一个host、service上展示相应的图形

设置如下：

编辑templates.cfg模板文件，创建host和service支持pnp4nagios功能：

define host {

  name    host-pnp

  action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_

  register  0

}

define service {

  name    srv-pnp

  action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$

  register  0

}

定义完成之后，最后只需在定义的hosts、services配置文件中加入下操作：

define host{

    use           linux-server,host-pnp   ; Name of host templates to use

                             ; This host definition will inherit all variables that are defined

                             ; in (or inherited by) the linux-server host template definition.

    host_name        localhost

    alias          localhost

    address         127.0.0.1

    }

define service{

    use           local-service,srv-pnp  ; Name of service template to use

    host_name        localhost

    service_description   PING

    check_command      check_ping!100.0,20%!500.0,60%

    }

于是整个配置工作完成，访问浏览器出图如下

至此结合图形展示成功
