為nagios裝上pnp4nagios功能-創(chuàng)新互聯(lián)

nagios的安裝不再贅述,直接在nagios服務(wù)端進(jìn)行安裝pnp4nagios軟件

安裝展示圖形頁面pnpnagios(rrdtool工具用來存儲數(shù)據(jù)并畫圖,pnpnagios用來展示圖形數(shù)據(jù))

參考: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

編譯報錯:

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

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

解決辦法:

yum -y install perl-Time-HiRes

再次編譯

./configure

make all

make install

make install-webconf

make install-config

make install-init

make fullinstall

安裝后出現(xiàn)如下輸出:

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

在官方文檔有好幾種配置pnp4nagios的模式,但是采用sync的模式會一直收集不到數(shù)據(jù),而報錯,于是改用了Bulk Mode with NPCD,成功出圖,這里分析配置過程:

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

1、編輯nagios.cfg文件,修改

process_performance_data=0將這個值改為1

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

enable_environment_macros=1

2、然后去掉下面兩個注釋,使之啟用:

#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

各個文件的使用可以查看官方說明

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.$TIMET$

}

然后開啟npcd服務(wù):

/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:                        [確定]

正在啟動 httpd:

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

Running configuration check...

Reloading nagios configuration...

done

5、瀏覽器訪問

http://192.168.1.155/pnp4nagios/

出現(xiàn)報錯:PHP GD extensionPHP GD extension not available

解決:

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:                        [確定]

正在啟動 httpd:

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

Running configuration check...

Reloading nagios configuration...

done

再看觀察瀏覽器報錯:

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

解決辦法:

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

以上只是解決了收集數(shù)據(jù)的功能,還必須在每一個host、service上展示相應(yīng)的圖形

設(shè)置如下:

編輯templates.cfg模板文件,創(chuàng)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

}

定義完成之后,最后只需在定義的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%

    }

于是整個配置工作完成,訪問瀏覽器出圖如下
