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。
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。

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
