3.14. 自动化安装cacti服务器¶
一、目的
1.1 监控目的
目前我们已经有zabbix监控系统，但是有客户需求需要流量报表，因此应此类客户的需求，部署Cacti流量监控系统，来监控客户服务器或交换机端口，为客户提供流量报表截图。
1.2 本文目的
快速部署Cacti流量监控系统，为后期相关工程师部署此系统提供借鉴与参考。
二、理论基础
2.1 相关理论
Cacti是用php语言实现的一套基于PHP,MySQL,SNMP及RRDTool开发的网络流量监测图形分析工具。snmp服务获取数据，然后用rrdtool储存和更新数据，当用户需要查看数据的时候用rrdtool生成图表呈现给用户。
