shell脚本监控阿里云专线网络状态，若不统统过触发阿里云的进程监控报警

#!/bin/bash

while [ 1 ]
  
do

   rtt=`ping -c 3 15.0.160.18 |grep rtt |awk '{print $4}' |awk -F'/' '{print $2}'`
   rtt=${rtt:-'0'}
   echo  $rtt >> /tmp/jianhang_tunnel_monitor.log

   if [ $rtt -eq 0  ];then
      ps -fe|grep tunnel|grep -v grep|awk '{print $2}'|xargs kill -9
      echo "jianhang tunnel is not stable " >> /tmp/jianhang_tunnel_monitor.log

   fi
   sleep 60

done

　　

若专线对端ping 的延时 rtt 为0 , 脚本自动kill 掉本身的 montior进程， 经过阿里云的云监控进程监控来触发报警
