Nagios插件Nagiosgraph安裝部署
Nagios是比較常用的一款開源監控軟件,Nagios靈活輕便使得在使用時可以根據自己的實際情況靈活運用,但是Nagios有一個缺點是對繪圖做的不夠完善,所以在對監控數據用來做分析時Nagios就有短板了。不過因為Nagios的靈活所以Nagios可以借助其他的方式實現圖形報表的展示,今天在此就簡要的說一說官方的Nagiosgraph插件,Nagiosgraph插件是用過Perl來實現的,所以在使用用Nagiosgraph插件時就要確保系統中安裝了Perl以及配置好相應的cpan源,這樣才能進行安裝,至於cpan的源配置以前有提及過,這裏就不做說明,需要可以參看:http://jim123.blog.51cto.com/4763600/1895093 。Nagiosgraph插件的官方下載地址:https://sourceforge.net/projects/nagiosgraph/files/ ,建議下載最新穩定版,安裝部署前需要先檢查系統中是否有安裝插件所需的依賴包:
[[email protected] nagiosgraph-1.5.2]# perl install.pl --check-prereq#像這樣就是所有的插件都有安裝了 checking required PERL modules Carp...1.11 CGI...3.51 Data::Dumper...2.124 Digest::MD5...2.39 File::Basename...2.77 File::Find...1.14 MIME::Base64...3.08 POSIX...1.17 RRDs...1.3008 Time::HiRes...1.9721 checking optional PERL modules GD...2.44 Nagios::Config...36 checking nagios installation found nagios exectuable at /usr/local/nagios/bin/nagios found nagios init script at /etc/init.d/nagios checking web server installation found apache executable at /usr/sbin/httpd found apache init script at /etc/init.d/httpd
如果找到那一沒有安裝就安裝下,建議在配置好yum源或者是apt源後進行安裝如GD繪圖安裝:
[[email protected] nagiosgraph-1.5.2]# yum -y install perl-GD
這裏一般都會缺少安裝Perl下的Nagios::Config模塊,在配置好cpan源後使用cpan安裝
[[email protected] nagiosgraph-1.5.2]# cpan Nagios::Config#註意有的時候還會缺少Digest::MD5模塊等同理依次安裝即可
在解決所有的依賴關系後就可以開始安裝配置,在安裝時會有提示默認選項直接按回車就進行下一步
[[email protected] nagiosgraph-1.5.2]# perl install.pl
在安裝好後需要註意,最後會有提示需要在Nagios中做一些配置更改配置及操作方法,如:
# process nagios performance data using nagiosgraph process_performance_data=1 service_perfdata_file=/tmp/perfdata.log service_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$ service_perfdata_file_mode=a service_perfdata_file_processing_interval=30 service_perfdata_file_processing_command=process-service-perfdata-for-nagiosgraph #修改Nagios的配置文件,在nagios.cfg添加 /bin/systemctl restart httpd.service * In the nagios commands file (command.cfg), add these lines: # command to process nagios performance data for nagiosgraph define command { command_name process-service-perfdata-for-nagiosgraph command_line /usr/local/nagiosgraph/bin/insert.pl } #添加修改command.cfg配置文件 * In the apache configuration file (httpd.conf), add this line: Include /usr/local/nagiosgraph/etc/nagiosgraph-apache.conf #在Nagios的用的httpd配置文件中添加nagiosgraph的包含 * Check the nagios configuration: /usr/local/nagios/bin/nagios -v /path/to/nagios.cfg * Restart nagios to start data collection: /etc/init.d/nagios restart * Restart apache to enable display of graphs: /etc/init.d/httpd restart #最後在多項檢查重啟後完成配置 * To enable graph links and mouseovers, see README sections: Displaying Per-Service and Per-Host Graph Icons and Links Displaying Graphs in Nagios Mouseovers
同Nagios一樣打開頁面配置檢查頁面:http://IP/nagiosgraph/cgi-bin/showconfig.cgi
確認沒有問題後再到Nagios的share文件夾下修改Nagios的php頁面文件side.php添加Nagiosgraph的鏈接制作偽靜態頁:
<?php $nagiosgraph_path = ‘/nagiosgraph/cgi-bin‘;?> <li><a >Nagios圖表</a></li> <ul> <li><a href="<?php echo $nagiosgraph_path;?>/show.cgi" target="<?php echo $link_target;?>">圖表</a></li> <li><a href="<?php echo $nagiosgraph_path;?>/showhost.cgi" target="<?php echo $link_target;?>">主機圖表</a></li> <li><a href="<?php echo $nagiosgraph_path;?>/showservice.cgi" target="<?php echo $link_target;?>">服務圖表</a></li> <li><a href="<?php echo $nagiosgraph_path;?>/showgroup.cgi" target="<?php echo $link_target;?>">主機組圖表</a></li> </ul> </li>
最後在Nagios的頁面下就有Nagiosgraph的圖表鏈接
根據要選定的主機和服務生成圖表,總之Nagiosgraph的配置是依賴於Perl配置起來還是比較簡單的,但是生成的圖表並不是非常的完美,不過也能滿足日常的一些簡單的分析,但是如果需要更好可以借助替他軟件或插件實現,Nagios的圖表展示。
