Cacti和Nagios整合

        Cacti是一套基于PHP,MySQL,SNMP及RRDTool开发的网络流量监测图形分析工具。用来监控网络流量、cpu使用率、内存使用率、硬盘使用率等。可以直观的监控各种数据流量,可以安装扩展插件,同时支持短信邮件告警等功能。

成都创新互联公司:2013年至今为各行业开拓出企业自己的“网站建设”服务,为近千家公司企业提供了专业的网站设计、网站建设、网页设计和网站推广服务, 按需网站制作由设计师亲自精心设计,设计的效果完全按照客户的要求,并适当的提出合理的建议,拥有的视觉效果,策划师分析客户的同行竞争对手,根据客户的实际情况给出合理的网站构架,制作客户同行业具有领先地位的。

        Nagios是一个监视系统运行状态和网络信息的监视系统。Nagios能监视所指定的本地或远程主机以及服务,提供异常通知功能,同时还可以安装各种模块插件,自定义监控脚本等。

        两者区别:Cacti偏重于网络流量,系统负载方面的监控。而 Nagios偏重于系统服务方面的监控,你可以在被监控的机器上写自己的程序(shell,c 或 perl都可以) 。Nagios则通过这些脚本来对服务进行监控。Nagios可以和短信发送机配合用来监控规模较大的网站。

        Nagios executable:  nagios
        Nagios user/group:  nagios,nagios
       Command user/group:  nagios,nagcmd
             Event Broker:  yes
        Install ${prefix}:  /usr/local/nagios
    Install ${includedir}:  /usr/local/nagios/include/nagios
                Lock file:  ${prefix}/var/nagios.lock
   Check result directory:  ${prefix}/var/spool/checkresults
           Init directory:  /etc/rc.d/init.d
  Apache conf.d directory:  /etc/httpd/conf.d

 ------------------------
                 HTML URL:  http://localhost/nagios/
                  CGI URL:  http://localhost/nagios/cgi-bin/
 Traceroute (used by WAP):

Review the options above for accuracy.  If they look okay,

type 'make all' to compile the main program and CGIs.

  • 安装

[root@www nagios-4.1.1]# make all

*** Compile finished ***

If the main program and CGIs compiled without any errors, you

can continue with installing Nagios as follows (type 'make'

without any arguments for a list of all possible options):

  make install

     - This installs the main program, CGIs, and HTML files

  make install-init

     - This installs the init script in /etc/rc.d/init.d

  make install-commandmode

     - This installs and configures permissions on the

       directory for holding the external command file

  make install-config

     - This installs *SAMPLE* config files in /etc/nagios

       You'll have to modify these sample files before you can

       use Nagios.  Read the HTML documentation for more info

       on doing this.  Pay particular attention to the docs on

       object configuration files, as they determine what/how

       things get monitored!

  make install-webconf

     - This installs the Apache config file for the Nagios

       web interface

  make install-exfoliation

     - This installs the Exfoliation theme for the Nagios

       web interface

  make install-classicui

     - This installs the classic theme for the Nagios

       web interface
