Nagios插件Nagiosgraph安装部署

2017-08-14 23:23 399 查看
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。
