需求描述:
在安装完成nagios之后,比如有监控磁盘负载信息的,连接数的,进程数的,可以通过安装nagiosgraph软件,
将nagios的性能数据绘制成图表,可以看到一段时间内数据的变化
环境说明:
操作系统版本:RedHat_6.6_x64
安装过程:
1.下载,上传nagiosgraph软件

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.
