nagios 圖形化界面之三 （nagiosgraph）

   如今，監控系統是琳瑯滿目，有Nagios、Cacti、Zabbix、Centreon、Munin等，也有系統集成如FAN等。個人在經過不同監控的安裝測試后，還是比較傾向于Nagios的監控，簡單命令；而且結合nagios和pnp4nagios等插件可以實現圖表的功能。

    Nagios、Nagiosgraph 使用的是RRDtool工具來實現畫圖的。

1：安裝依賴

            (1) .  rrdtool  安裝rrdtool-1.4.5.tar.gz

            (2) .  GD的perl模塊

         GD模塊依賴于gd-devel等開發包。

2:  解壓安裝nagiosgraph-1.4.4.tar.gz

           tar  zxvf nagiosgraph-1.4.4.tar.gz

           cd   nagiosgraph-1.4.4

       以下都是在nagiosgraph-1.4.4目錄下完成的,安裝前檢測安裝環境

[root@localhostnagiosgraph-1.4.4]# perl install.pl--check-prereq

checking required PERL modules

Carp...1.20

CGI... ***FAIL***

Data::Dumper...2.130_02

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!

以上是我的結果，錯誤是perl的cgi模塊沒有安裝

使用yum 安裝，如下

yum install perl-CGI

重新檢驗

perl install.pl --check-prereq

結果就正確了

安裝

perl install.pl//安裝命令

出現的結果如下，注意后面最好不要一路回車，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

注意最后出現的這幾行，這是對于以后nagiosgraph的配置信息

  （1）：在nagios的配置文件（nagios.cfg）中加入以下幾行

# 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)中加入以下幾行

# 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第一個字母大寫

  （4）：重啟nagio和httpd后登錄nagiosgraph

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

出現以下結果

可以先選擇host然后點擊update graphs 然后，在左上角再點擊data for host……中的主機名稱就可以了

 （5）：把nagiosgraph路徑加到nagios系統內

在/usr/local/nagios/share/side.php加入如下內容

<?php$nagiosgraph_path='/nagiosgraph/cgi-bin';?>

<li><a >Nagiosgraph</a>

<ul>

<li><a href="<?phpecho$nagiosgraph_path;?>/show.cgi" target="<?phpecho$link_target;?>">Graphs</a></li>

<li><a href="<?phpecho$nagiosgraph_path;?>/showhost.cgi" target="<?phpecho$link_target;?>">Graphs by Host</a

></li>

<li><a href="<?phpecho$nagiosgraph_path;?>/showservice.cgi" target="<?phpecho$link_target;?>">Graphs by Serv

ice</a></li>

<li><a href="<?phpecho$nagiosgraph_path;?>/showgroup.cgi" target="<?phpecho$link_target;?>">Graphs by Group<

/a></li>

</ul>

</li>

其實就是nagiosweb 界面的reports欄加入了trends如下
