nagios 图形化界面之三 （nagiosgraph）
如今，监控系统是琳琅满目，有Nagios、Cacti、Zabbix、Centreon、Munin等，也有系统集成如FAN等。个人在经过不同监控的安装测试后，还是比较倾向于Nagios的监控，简单命令；而且结合nagios和pnp4nagios等插件可以实现图表的功能。Nagios、Nagiosgraph 使用的是RRDtool工具来实现画图的。
1：安装依赖
(1) .rrdtool安装rrdtool-1.4.5.tar.gz
(2) .GD的perl模块
GD模块依赖于gd-devel等开发包。
2:解压安装nagiosgraph-1.4.4.tar.gz
tarzxvf nagiosgraph-1.4.4.tar.gz
cd nagiosgraph-1.4.4
以下都是在nagiosgraph-1.4.4目录下完成的,安装前检测安装环境
[root@localhostnagiosgraph-1.4.4]# perl install.pl--check-prereq
checking required PERL modules
Carp...1.20

GD...***FAIL***
checking nagios installation
found nagios at /usr/local/nagios/bin/nagios
checking web server installation
found apache at /usr/sbin/httpd
*** one or more problems were detected!
以上是我的结果，错误是perl的cgi模块没有安装
使用yum 安装，如下
yum install perl-CGI
重新检验
perl install.pl --check-prereq
结果就正确了
安装
perl install.pl//安装命令
出现的结果如下，注意后面最好不要一路回车，自己多注意一下都是什么要求

To complete theinstallation, do the following:
* In the nagios configuration file (e.g.nagios.cfg),
add these lines:
# process nagiosperformance 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
* In the nagios commands file (e.g.command.cfg),
add these lines:
# command to processnagios performance data for nagiosgraph
define command {
command_nameprocess-service-perfdata-for-nagiosgraph
command_line/usr/local/nagios/nagiosgraph/bin/insert.pl
}
* In the apache configuration file (e.g.httpd.conf),
add this line:
include/usr/local/nagios/nagiosgraph/etc/nagiosgraph-apache.conf
* Restart nagios to start data collection:
/etc/init.d/nagiosrestart
* Restart apache to enable display of graphs:
/etc/init.d/apacherestart
* To enable graph links and mouseovers, seeREADME sections:
Displaying Per-Service and Per-HostGraph Icons and Links
Displaying Graphs in Nagios Mouseovers
注意最后出现的这几行，这是对于以后nagiosgraph的配置信息
（1）：在nagios的配置文件（nagios.cfg）中加入以下几行
# process nagiosperformance 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
（2）：在nagios命令文件(command.cfg)中加入以下几行
# command to processnagios performance data for nagiosgraph
define command {
command_nameprocess-service-perfdata-for-nagiosgraph
command_line/usr/local/nagios/nagiosgraph/bin/insert.pl
}
（3）：在apache配置文件httpd.conf中加入
include/usr/local/nagios/nagiosgraph/etc/nagiosgraph-apache.conf
注意include第一个字母大写
（4）：重启nagio和httpd后登录nagiosgraph
http://localhost/nagiosgraph/cgi-bin/show.cgi
出现以下结果
可以先选择host然后点击update graphs 然后，在左上角再点击data for host……中的主机名称就可以了
（5）：把nagiosgraph路径加到nagios系统内
在/usr/local/nagios/share/side.php加入如下内容Nagiosgraph
[*]Graphs
[*]Graphs by Host
[*]Graphs by Service
[*]Graphs by Group
其实就是nagiosweb 界面的reports栏加入了trends如下
俺从不写措字，但俺写通假字! 做爱做的事，交配交的人。 微机原理闹危机，随机过程随机过，实变函数学十遍，汇编语言不会编！ 恋爱就是无数个饭局，结婚就是一个饭局。 人生自古谁无死，啊个拉屎不用纸! 走自己的路，让别人打车去吧。
