需求描述:

　　在安裝完成nagios之后,比如有監控磁盤負載信息的,連接數的,進程數的,可以通過安裝nagiosgraph軟件,

　　將nagios的性能數據繪制成圖表,可以看到一段時間內數據的變化

環境說明:

　　操作系統版本:RedHat_6.6_x64

安裝過程:

1.下載,上傳nagiosgraph軟件

下載地址: https://sourceforge.net/projects/nagiosgraph/files/

軟件版本:nagiosgraph-1.5.2.tar.gz

[root@testvm02 ~]# cd /opt/softwares/;ls -l nagiosgrap* -rw-r--r--. 1 root root 329978 Jul 31 14:12 nagiosgraph-1.5.2.tar.gz

2.解壓軟件,執行預安裝檢查

[root@testvm02 softwares]# tar zxf nagiosgraph-1.5.2.tar.gz [root@testvm02 softwares]# cd nagiosgraph-1.5.2 [root@testvm02 nagiosgraph-1.5.2]# ./install.pl --check-prereq checking required PERL modulesCarp...1.11CGI... ***FAIL*** #針對這個報錯,安裝perl-CGIData::Dumper...2.124Digest::MD5...2.39File::Basename...2.77File::Find...1.14MIME::Base64...3.08POSIX...1.17RRDs... ***FAIL*** #針對這個錯誤安裝rrdtool,并且rrdtool,安裝rrdtool-perlTime::HiRes... ***FAIL*** #針對這個報錯,安裝perl-Time-HiRes checking optional PERL modulesGD... ***FAIL*** #針對這個錯誤安裝perl-GDNagios::Config... ***FAIL*** #針對這個錯誤安裝perl-Nagios-Object checking nagios installationfound nagios exectuable at /usr/local/nagios/bin/nagiosfound nagios init script at /etc/init.d/nagios checking web server installationfound apache executable at /usr/sbin/httpdfound apache init script at /etc/init.d/httpd*** one or more problems were detected!

3.安裝需要的軟件包

[root@testvm02 nagiosgraph-1.5.2]# yum install perl-CGI
[root@testvm02 nagiosgraph-1.5.2]# yum install perl-Time-HiRes
[root@testvm02 softwares]# yum install rrdtool

perl模塊下載地址:http://rpmfind.net/linux/RPM/index.html? (可以下載上面提到的軟件)

當出現以下的配置檢查結果,表示可以進行安裝

[root@testvm02 nagiosgraph-1.5.2]# ./install.pl --check-prereq checking required PERL modulesCarp...1.11CGI...3.51Data::Dumper...2.124Digest::MD5...2.39File::Basename...2.77File::Find...1.14MIME::Base64...3.08POSIX...1.17RRDs...1.3008Time::HiRes...1.9721 checking optional PERL modulesGD...2.44Nagios::Config...36 checking nagios installationfound nagios exectuable at /usr/local/nagios/bin/nagiosfound nagios init script at /etc/init.d/nagios checking web server installationfound apache executable at /usr/sbin/httpdfound apache init script at /etc/init.d/httpd

4.安裝nagiosgraph軟件

[root@testvm02 nagiosgraph-1.5.2]# ./install.pl

備注:一路回車就可以了.

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 (command.cfg),add these lines:# command to process nagios performance data for nagiosgraph define command {command_name process-service-perfdata-for-nagiosgraphcommand_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 LinksDisplaying Graphs in Nagios Mouseovers

5.配置nagiosgraph

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

# 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

　　5.2 在nagios的命令文件commands.cfg(默認位置:/usr/local/nagios/etc/objects)中加入以下內容

# command to process nagios performance data for nagiosgraph define command {command_name process-service-perfdata-for-nagiosgraphcommand_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)加入以下內容

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

　　5.4 檢查nagios配置,如果沒有問題,就表示增加的配置是正確,如果配置錯誤,會有提示

[root@testvm02 conf]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfgNagios Core 4.4.1 Copyright (c) 2009-present Nagios Core Development Team and Community Contributors Copyright (c) 1999-2009 Ethan Galstad Last Modified: 2018-06-25 License: GPLWebsite: https://www.nagios.org Reading configuration data...Read main config file okay...Read object config files okay...Running pre-flight check on configuration data...Checking objects...Checked 8 services.Checked 1 hosts.Checked 1 host groups.Checked 0 service groups.Checked 1 contacts.Checked 1 contact groups.Checked 25 commands.Checked 5 time periods.Checked 0 host escalations.Checked 0 service escalations.

　　5.5 重啟nagios,啟動收集數據,重啟httpd來顯示圖表

[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.通過以下命令,查看nagiosgraph已經運行

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

7.針對某些數據,可以看圖

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

選擇對應的服務就能夠查看圖表:

備注:這個是在特定的頁面進行特定服務的查看.

8.在nagios的template.cfg文件中增加nagiosgraph的實例信息

define service {name graphed-serviceaction_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+450+-jregister 0}

?9.針對具體的服務加上圖表連接,將前面定義的graphed-service加入到具體的service定義中(以本地服務為例,localhost.cfg文件)

vi localhost.cfg
define service {

??? use???????????????????? local-service,graphed-service?????????? ; Name of service template to use #在每一個的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.重啟nagios加載新的配置文件

service nagios restart

11.查看nagios頁面的顯示,在Service字段后面有了一個圖片的連接,點擊可以連接到具體的服務產生的圖

12.可以更換這個圖片

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.重新刷新頁面,圖標已經更換

到此,nagiosgraph已經安裝完成,其他的可以在根據使用需求,查看官方文檔.
