Nagios是比较常用的一款开源监控软件,Nagios灵活轻便使得在使用时可以根据自己的实际情况灵活运用,但是Nagios有一个缺点是对绘图做的不够完善,所以在对监控数据用来做分析时Nagios就有短板了。不过因为Nagios的灵活所以Nagios可以借助其他的方式实现图形报表的展示,今天在此就简要的说一说官方的Nagiosgraph插件,Nagiosgraph插件是用过Perl来实现的,所以在使用用Nagiosgraph插件时就要确保系统中安装了Perl以及配置好相应的cpan源,这样才能进行安装,至于cpan的源配置以前有提及过,这里就不做说明,需要可以参看:http://jim123.blog.51cto.com/4763600/1895093 。Nagiosgraph插件的官方下载地址:https://sourceforge.net/projects/nagiosgraph/files/ ,建议下载最新稳定版,安装部署前需要先检查系统中是否有安装插件所需的依赖包:
[root@localhost nagiosgraph-1.5.2]# perl install.pl --check-prereq#像这样就是所有的插件都有安装了 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
如果找到那一没有安装就安装下,建议在配置好yum源或者是apt源后进行安装如GD绘图安装:
[root@localhost nagiosgraph-1.5.2]# yum -y install perl-GD
这里一般都会缺少安装Perl下的Nagios::Config模块,在配置好cpan源后使用cpan安装
[root@localhost nagiosgraph-1.5.2]# cpan Nagios::Config#注意有的时候还会缺少Digest::MD5模块等同理依次安装即可
在解决所有的依赖关系后就可以开始安装配置,在安装时会有提示默认选项直接按回车就进行下一步
[root@localhost nagiosgraph-1.5.2]# perl install.pl
在安装好后需要注意,最后会有提示需要在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 #最后在多项检查重启后完成配置 * 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一样打开页面配置检查页面:http://IP/nagiosgraph/cgi-bin/showconfig.cgi
确认没有问题后再到Nagios的share文件夹下修改Nagios的php页面文件side.php添加Nagiosgraph的链接制作伪静态页:
<?php $nagiosgraph_path = ‘/nagiosgraph/cgi-bin‘;?> <li><a >Nagios图表</a></li> <ul> <li><a href="<?php echo $nagiosgraph_path;?>/show.cgi" target="<?php echo $link_target;?>">图表</a></li> <li><a href="<?php echo $nagiosgraph_path;?>/showhost.cgi" target="<?php echo $link_target;?>">主机图表</a></li> <li><a href="<?php echo $nagiosgraph_path;?>/showservice.cgi" target="<?php echo $link_target;?>">服务图表</a></li> <li><a href="<?php echo $nagiosgraph_path;?>/showgroup.cgi" target="<?php echo $link_target;?>">主机组图表</a></li> </ul> </li>
最后在Nagios的页面下就有Nagiosgraph的图表链接
根据要选定的主机和服务生成图表,总之Nagiosgraph的配置是依赖于Perl配置起来还是比较简单的,但是生成的图表并不是非常的完美,不过也能满足日常的一些简单的分析,但是如果需要更好可以借助替他软件或插件实现,Nagios的图表展示。
