chmod  on /usr/local/nagiosgraph/var/log/nagiosgraph-cgi.log

chown apache,- on /usr/local/nagiosgraph/var/log/nagiosgraph-cgi.log

  To complete the installation, do the following:

  * In the nagios configuration file (nagios.cfg),

    add these lines:

# process nagios performance data using nagiosgraph

process_performance_data=

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=

service_perfdata_file_processing_command=process-service-perfdata-for-nagiosgraph

  * 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

}

  * In the apache configuration file (httpd.conf),

    add this line:

include /usr/local/nagiosgraph/etc/nagiosgraph-apache.conf

  * 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

  * To enable graph links and mouseovers, see README sections:

       Displaying Per-Service and Per-Host Graph Icons and Links

       Displaying Graphs in Nagios Mouseovers

5.配置nagiosgraph

　　5.1 在nagios.cfg中增加以下配置(nagios.cfg文件默认位置:/usr/local/nagios/etc)

# process nagios performance data using nagiosgraph

process_performance_data=

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=

service_perfdata_file_processing_command=process-service-perfdata-for-nagiosgraph

　　5.2 在nagios的命令文件commands.cfg(默认位置:/usr/local/nagios/etc/objects)中加入以下内容

# 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

}

　　5.3 在apache的配置文件httpd.conf(文件位置:/etc/httpd/conf)加入以下内容

/usr/local/nagios/bin/nagios -v /path/to/nagios.cfg

　　5.4 检查nagios配置,如果没有问题,就表示增加的配置是正确,如果配置错误,会有提示

[root@testvm02 conf]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Nagios Core 4.4.

　　5.5 重启nagios,启动收集数据,重启httpd来显示图表

[root@testvm02 conf]# service nagios restart

Running configuration check... Stopping nagios: done.

Starting nagios: Running configuration check... done.

[root@testvm02 conf]# service httpd restart

Stopping httpd:                                            [  OK  ]

Starting httpd: httpd: apr_sockaddr_info_get() failed for testvm02

httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

                                                           [  OK  ]

6.通过以下命令,查看nagiosgraph已经运行

http://192.168.53.25/nagiosgraph/cgi-bin/showconfig.cgi

7.针对某些数据,可以看图

http://192.168.53.25/nagiosgraph/cgi-bin/show.cgi

选择对应的服务就能够查看图表:

备注:这个是在特定的页面进行特定服务的查看.

8.在nagios的template.cfg文件中增加nagiosgraph的实例信息

     define service {

       name graphed-service

       action_url /nagiosgraph/cgi-bin/show.cgi?host=$HOSTNAME$&service=$SERVICEDESC$' onMouseOver='showGraphPopup(this)' onMouseOut='hideGraphPopup()' rel='/nagiosgraph/cgi-bin/showgraph.cgi?host=$HOSTNAME$&service=$SERVICEDESC$&period=week&rrdopts=-w++-j

       register

     }

9.针对具体的服务加上图表连接,将前面定义的graphed-service加入到具体的service定义中(以本地服务为例,localhost.cfg文件)

vi localhost.cfg
define service {

    use                     local-service,graphed-service           ; Name of service template to use  #在每一个的service的后面都加上graphed-service
    host_name               localhost
    service_description     PING
    check_command           check_ping!100.0,20%!500.0,60%
}

10.重启nagios加载新的配置文件

service nagios restart

11.查看nagios页面的显示,在Service字段后面有了一个图片的连接,点击可以连接到具体的服务产生的图

12.可以更换这个图片

mv /usr/local/nagios/share/images/action.gif /usr/local/nagios/share/images/action.gif-orig

[root@testvm02 objects]# cd /opt/softwares/nagiosgraph-1.5.2
[root@testvm02 nagiosgraph-1.5.2]# cp share/graph.gif /usr/local/nagios/share/images/action.gif

13.重新刷新页面,图标已经更换

到此,nagiosgraph已经安装完成,其他的可以在根据使用需求,查看官方文档.
