Nagios是比較常用的一款開源監視軟體,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,所以在對監控資料用來做分析時Nagios就有短板了。不過因為Nagios的靈活所以Nagios可以藉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外掛程式,Nagiosgraph外掛程式是用過Perl來實現的,所以在使用用Nagiosgraph外掛程式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,這裡就不做說明,需要可以參看:http://jim123.blog.51cto.com/4763600/1895093 。Nagiosgraph外掛程式的官方: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外掛程式所需的依賴包:
[[email protected] nagiosgraph-1.5.2]# perl install.pl --check-prereq#像這樣就是所有的外掛程式都有安裝了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...1.9721checking optional PERL modules GD...2.44 Nagios::Config...36checking nagios installation found nagios exectuable at /usr/local/nagios/bin/nagios found nagios init script at /etc/init.d/nagioschecking 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
這裡一般都會缺少安裝Perl下的Nagios::Config模組,在配置好cpan源後使用cpan安裝
[[email protected] nagiosgraph-1.5.2]# cpan Nagios::Config#注意有的時候還會缺少Digest::MD5模組等同理依次安裝即可
在解決所有的依賴關係後就可以開始安裝配置,在安裝時會有提示預設選項直接按斷行符號就進行下一步
[[email protected] nagiosgraph-1.5.2]# perl install.pl
在安裝好後需要注意,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 nagiosgraphprocess_performance_data=1service_perfdata_file=/tmp/perfdata.logservice_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$service_perfdata_file_mode=aservice_perfdata_file_processing_interval=30service_perfdata_file_processing_command=process-service-perfdata-for-nagiosgraph#修改Nagios的設定檔,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 nagiosgraphdefine command { command_name process-service-perfdata-for-nagiosgraph command_line /usr/local/nagiosgraph/bin/insert.pl}#添加修改command.cfg設定檔 * In the apache configuration file (httpd.conf), add this line:Include /usr/local/nagiosgraph/etc/nagiosgraph-apache.conf#在Nagios的用的httpd設定檔中添加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一樣開啟頁面配置檢查頁面:http://IP/nagiosgraph/cgi-bin/showconfig.cgi650) this.width=650;" src="https://s4.51cto.com/wyfs02/M01/9E/80/wKiom1mRvMWxYUThAABZ5H2rJ4g901.png-wh_500x0-wm_3-wmp_4-s_4178348816.png" title="Nagiosgraph配置檢查頁面" alt="wKiom1mRvMWxYUThAABZ5H2rJ4g901.png-wh_50" />
確認沒有問題後再到Nagios的share檔案夾下修改Nagios的php分頁檔side.php添加Nagiosgraph的連結製作偽靜態頁:
<?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;?>">主機群組圖表</a></li></ul></li>
最後在Nagios的頁面下就有Nagiosgraph的圖錶鏈接650) this.width=650;" src="https://s1.51cto.com/wyfs02/M00/9E/81/wKiom1mRvtuDO8zTAAOki0Wprh8171.png-wh_500x0-wm_3-wmp_4-s_4248651793.png" title="Nagiosgraph圖錶鏈接" alt="wKiom1mRvtuDO8zTAAOki0Wprh8171.png-wh_50" />

根據要選定的主機和服務組建圖表,總之Nagiosgraph的配置是依賴於Perl配置起來還是比較簡單的,但是產生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藉助替他軟體或外掛程式實現,Nagios的圖表展示。
