NAGIOS插件pnp4nagios安裝

NAGIOS插件pnp4nagios安裝
注：nagios版本nagios4.0.8

1.下載安裝 pnp4nagios-0.6.25.tar.gz

wget http://sourceforge.net/projects/pnp4nagios/files/PNP-0.6/pnp4nagios-0.6.25.tar.gz

yum -y install rrdtool perl-Time-HiRes perl-File-Tail rrdtool rrdtool-perl php-gd

tar zxvf  pnp4nagios-0.6.25.tar.gz

cd pnp4nagios-0.6.25

#perl -MRRDs -le 'print q(ok!)'
如果返回值是ok!，則可以進行pnp4nagios配置和安裝
#./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/bin/rrdtool --with-perl_lib_path=/usr/lib64/perl5/vendor_perl/auto/RRDs
#make all
#make install
#make install-webconf
#make install-config
#make install-init

2.創建配置文件

cd /usr/local/pnp4nagios/etc

mv misccommands.cfg-sample  misccommands.cfg

mv nagios.cfg-sample  nagios.cfg

mv npcd.cfg-sample npcd.cfg

mv process_perfdata.cfg-sample  process_perfdata.cfg

# mv rra.cfg-sample rra.cfg

#  cd pages

mv web_traffic.cfg-sample web_traffic.cfg

cd ../check_commands

mv check_all_local_disks.cfg-sample  check_all_local_disks.cfg

mv check_nrpe.cfg-sample  check_nrpe.cfg

mv check_nwstat.cfg-sample  check_nwstat.cfg

3. 重啓服務

   /etc/init.d/npcd restart

   echo “/etc/init.d/npcd start”>>/etc/rc.local
   4.修改 nagios 的配置文件.打開performance_data

   cd /usr/local/nagios/etc

   vim nagios.cfg

   #打開註釋項：
   process_performance_data=1
   host_perfdata_command=process-host-perfdata
   service_perfdata_command=process-service-perfdata
   #######################添加如下內容####################################
   service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
   service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICEC::HECKCOMMAND::$SERVICECHECKCOMMAND$\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 performancedata 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
   ###########################################################
   5.修改 commands.cfg

   cd /usr/local/nagios/etc/objects

   vim commands.cfg

   ##添加
   #################################################################
   define command{
   command_name process-service-perfdata
   command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/service-perfdata
   }

define command{
command_name process-host-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/host-perfdata
}

6. 添加小太陽模版，鑲嵌在nagios頁面上。

   vim templates.cfg

   在最後添加

   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services.cfg

   cd /usr/local/nagios/etc/objects

   #修改hosts.cfg

   vim hosts.cfg

   define host{
           use                     linux-server,host-pnp  
           host_name          wwwserver
           alias                     wwwserver
           address                  10.10.10.111
           }

修改 services.cfg

define service{
        use                          local-service,srv-pnp      
        host_name                    wwwserver
        service_description         PING
        check_command             check_ping!100.0,20%!500.0,60%
}
其他的主機和服務以此類推
檢查配置文件正確與否
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

返回值如上圖片，則重啓nagios
8.重啓 nagios 服務
#/etc/init.d/nagios restart
效果圖：

這時點擊小太陽會出現如下提示：The requested URL /pnp4nagios/graph was not found on this server.
解決方法如下：
原因，當你在pnp4nagios安裝的時候執行了make install-webconf，注意它生成了一個apache的配置文件。
你把這個文件：/etc/httpd/conf.d/pnp4nagios.conf 中的所有內容全部添加到apache的httpd.conf文件最後，再重新啓動nagios和apache就應該可以啦。

[root@monitor etc]# find / -name pnp4nagios.conf
/etc/httpd/conf.d/pnp4nagios.conf
[root@monitor etc]# vim /etc/httpd/conf.d/pnp4nagios.conf
[root@monitor etc]# cat /etc/httpd/conf.d/pnp4nagios.conf>>/usr/local/apache/conf/httpd.conf
#service httpd restart
#service Nagios restart
這時再點擊小太陽，會出現pnp4nagios的測試頁，結果如下：

告訴要刪掉或重命名/usr/local/pnp4nagios/share/install.php
故障2：
安裝測試：
http://monitor.dreamlive.tv//pnp4nagios/index.php

#cd /usr/local/pnp4nagios/share
#mv install.php install.php.bak
在此測試：顯示如下：

沒有圖像出現，主要原因就是：導致
解決方法：

改爲：

重啓httpd
結果就正常了

報如下錯誤

Yum -y install pango pango-devel
然後重啓系統
