Cacti和Nagios整合

        Cacti是一套基于PHP,MySQL,SNMP及RRDTool開發的網絡流量監測圖形分析工具。用來監控網絡流量、cpu使用率、內存使用率、硬盤使用率等。可以直觀的監控各種數據流量，可以安裝擴展插件，同時支持短信郵件告警等功能。

        Nagios是一個監視系統運行狀態和網絡信息的監視系統。Nagios能監視所指定的本地或遠程主機以及服務，提供異常通知功能，同時還可以安裝各種模塊插件，自定義監控腳本等。

        兩者區別：Cacti偏重于網絡流量，系統負載方面的監控。而 Nagios偏重于系統服務方面的監控，你可以在被監控的機器上寫自己的程序(shell,c 或 perl都可以) 。Nagios則通過這些腳本來對服務進行監控。Nagios可以和短信發送機配合用來監控規模較大的網站。

[root@sh ~]# /etc/init.d/snmpd start

• cacti服務端web設置，添加主機（Devices-->Add-->Description-->Hostname-->Host Template-->Number of Collection Threads-->SNMP Version-->Create---*Create Graphs for this Host-->選擇要監控的模塊）

• 將添加的主機加入到Graph Trees中
  

[root@www ~]# /usr/local/spine/bin/spine 
SPINE: Using spine config file [/etc/spine.conf]

二、添加nagios用戶和nagcmd組

• 把nagios和apache添加到nagcmd組里

[root@www ~]# useradd -s /sbin/nologin nagios

[root@www ~]# groupadd nagcmd

[root@www ~]# usermod -G nagcmd nagios

[root@www ~]# usermod -G nagcmd apache

[root@www ~]# id apache

uid=501(nagios) gid=501(nagios) groups=501(nagios),502(nagcmd)

[root@www ~]# mkdir /usr/local/nagios

[root@www ~]# chown -R nagios.nagios /usr/local/nagios

三、安裝nagios-4.1.1.tar.gz

[root@www ~]# tar zxf nagios-4.1.1.tar.gz

[root@www ~]# cd nagios-4.1.1

• 編譯

[root@www nagios-4.1.1]# ./configure --prefix=/usr/local/nagios --sysconfdir=/etc/nagios --with-command-group=nagcmd 
......
 General Options:
 -------------------------
        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
             Mail program:  /bin/mail
                  Host OS:  linux-gnu
          IOBroker Method:  epoll
 Web Interface Options:
 ------------------------
                 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.

• 安裝
  

[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
