这里的代码是监控区域内的所有IP地址，故障数量达到某个值后就触发告警

import os
import time
import re
import subprocess
import threading
from queue import Queue


ip_queue = Queue()
abnormal_num = 0
call_num = 1
name = os.path.split('C:/Users/Administrator/Desktop/zone')[-1]    # 获取文件名用于告警通知是哪个zone的网络故障
with open('C:/Users/Administrator/Desktop/zone', 'r') as z_ip:
    for line in z_ip:
        z_file = line.strip()
        ip_queue.put(z_file)

                                   stderr=subprocess.PIPE, shell=True)

        regex1 = re.findall(r'\w*%\w*', res1)[0]  # 获取丢包率，百分比

                if abnormal_num >= 3 and call_num == 1:   
                    call_num += 1  # 设置只触发一次告警
                    send_sms('down {}'.format(name))  # 这里就可以调用你编写的告警函数，我的代码未贴出来
