Zabbix 繪圖實現交換機端口描述

思路：        

python netsnmp模塊採集交換機SNMP信息，經過pyzabbix 鏈接Zabbix API 自動生成帶有端口描述信息的graph

測試環境 python2.7

   軟件包：

        net-snmp-5.4.4.tar.gz

        pyzabbix

net-snmp編譯參數

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

安裝pyzabbix

pip install pyzabbix

Zabbix API  item.create 好像不支持建立以SNMP的方法來建立的，因此這邊以以low level discovery方法來採集交換機的端口， 這邊事先手動建立以low level discove

-G 生成新的screen

-H  本身定義的主機名

-c  須要生成的列

-s 交換的ip地址， （這邊交換的ip地址可能會跟你的 Host name 不一樣）

-x 是否開啓建立graph的功能

-n 是否開啓screen 功能

注意 -C -s 若是沒有填正確的信息 腳本會報錯，這個後續改下

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出來啦

Screen 也出來了

這邊出來的是你剛纔low level discovery 定義的

如今你能夠改name了

這邊也就改變了

若是腳本有問問題請向我指出謝謝！
