监控交换机端口流量
1.交换机开启并配置snmp
Telnet交换机并进行如下配置：
snmp enable traps snmp //开启交换机snmp功能
snmp community s8606 ro //设置共同体，权限为只读
2.把交换机加入监控
如下图所示添加相对应IP的交换机
https://s4.运维网.com/wyfs02/M00/07/3F/wKiom1nF4CDSOFhiAAFLXwGx27U316.png-wh_500x0-wm_3-wmp_4-s_2893077999.png

Thold的应用
由于Cacti自带的流量监控阀值只能监控byte，因此我们得把字节转换为位（MB）
计算公式：1 bytes=8 bits=8/1021 Kb=8/1024/1024 Mb
https://s5.运维网.com/wyfs02/M01/A5/F0/wKioL1nF4CfCH9LWAACpfUCwzTw001.png-wh_500x0-wm_3-wmp_4-s_2653073855.png

Thold 声音报警
在cacti目录下，更新thold插件代码，实现thold声音报警
/cacti/plugins/thold/thold_graph.php
在463行的 if ( $row['thold_fail_count'] >= $row['thold_fail_trigger'] )把以下代码添加入{}内
print '';
Weathermap的应用
创建一个新的气象图，并给图的配置文件起一个名字
https://s5.运维网.com/wyfs02/M00/A5/F0/wKioL1nF30mQm-EjAABhTQ7PsLc602.png-wh_500x0-wm_3-wmp_4-s_901326503.png
