思路：
python netsnmp模块采集交换机SNMP信息，通过pyzabbix 连接Zabbix API 自动生成带有端口描述信息的graph
测试环境 python2.7
软件包：
net-snmp-5.4.4.tar.gz
pyzabbix
net-snmp编译参数
cd net-snmp-5.4.4 ./configure --with-python-modules --prefix=/usr/local/net-snmp --enable-developer-enable-shared make && make install cd python python2.7 setup.py install
安装pyzabbix
pip install pyzabbix
Zabbix API item.create 好像不支持创建以SNMP的方法来创建的，所以这边以以low level discovery方法来采集交换机的端口， 这边事先手动创建以low level discove

a.main() #对于多块板卡的生成的screen有点问题 后期会补上
-G 生成新的screen
-H 自己定义的主机名
-c 需要生成的列
-s 交换的ip地址， （这边交换的ip地址可能会跟你的 Host name 不同）
-x 是否开启创建graph的功能
-n 是否开启screen 功能
注意 -C -s 如果没有填正确的信息 脚本会报错，这个后续改下
例子： ./switch_desc_port_and_create_screen.py -G tom -H 10.0.10.100 -c 2 -C tom -s 10.0.10.100 -x True -n True
Graph出来啦
Screen 也出来了
这边出来的是你刚才low level discovery 定义的
现在你可以改name了
这边也就改变了
如果脚本有问问题请向我指出谢谢！
