Python封装zabbixget接口

Zabbix 是一款强大的开源网管监控工具，该工具的客户端与服务端是分开的，我们可以直接使用自带的zabbix_get命令来实现拉取客户端上的各种数据，在本地组装参数并使用Popen开子线程执行该命令，即可实现批量监测。

封装Engine类: 该类的主要封装了Zabbix接口的调用,包括最基本的参数收集.

当我们需要使用时，只需要定义变量调用即可，其调用代码如下。

from engine import Engine

if __name__ == "__main__":
    ptr_windows = Engine("127.0.0.1","10050")
    ret = ptr_windows.GetDisk()
    if len(ret) != 0:
        for item in ret:
            addr = item.get("Address")
            name = item.get("Name")
            type = item.get("Type")
            space = item.get("Free")
            if type != "UNKNOWN" and space != -1:
                print("地址: {} --> 盘符: {} --> 格式: {} --> 剩余空间: {}".format(addr,name,type,space))
