脚本电子邮件警报和ping [英] Script for email alert and ping

问题描述

我需要帮助来更新这个脚本，如果ping失败，将再派平到另一台主机（除了现在发送，如果ping失败的电子邮件）。
这怎么可能从这个脚本呢？

 ＃！/斌/庆典HOSTS =IP地址
COUNT = 4对HOSTS $ MYHOST
做
    数= $（平-c $ COUNT $ MYHOST | grep'可以接受'| awk的-F'，''{$打印2}| $一个
    如果[$算上-eq 0];然后
        ＃100％不合格
        回声服务器无法在$（日期）|邮件-s服务器关闭[e-mail]
        回声主持人：$ MYHOST下跌（平失败）在$（日期）
    科幻
DONE
 

解决方案

您可以把平的东西，在一个函数。你并不需要处理（的grep ）的平结果是：你可以依靠平返回退出状态。

 ＃！/斌/庆典
HOSTS =IP1 IP2 IP3 IP4 IP5
COUNT = 4pingtest（）{
  在$ @MYHOST
  做
    平-c$ COUNT$ MYHOST＆放大器;＆安培;返回1
  DONE
  返回0
}如果pingtest $ HOSTS
然后
  ＃100％不合格
  回声服务器无法在$（日期）|邮件-s服务器关闭[e-mail]
  回声所有主机（$主机）下降（平失败）在$（日期）
科幻
 

I need help to update this script to if ping fails it would send another ping to another host (besides the email which is sent now if ping fails). How can this be done from this script?

#!/bin/bash

HOSTS="IP ADRESS"
COUNT=4

for myHost in $HOSTS
do
    count=$(ping -c $COUNT $myHost | grep 'received' | awk -F',' '{ print $2 }' | a$
    if [ $count -eq 0 ]; then
        # 100% failed
        echo "Server failed at $(date)" | mail -s "Server Down" [e-mail]
        echo "Host : $myHost is down (ping failed) at $(date)"
    fi
done

解决方案

You can put the ping stuff in a function. You do not need to process (grep) the ping result: you can rely on ping return exit status.

#!/bin/bash
HOSTS="IP1 IP2 IP3 IP4 IP5"
COUNT=4

pingtest(){
  for myHost in "$@"
  do
    ping -c "$COUNT" "$myHost" && return 1
  done
  return 0
}

if pingtest $HOSTS
then
  # 100% failed
  echo "Server failed at $(date)" | mail -s "Server Down" [e-mail]
  echo "All hosts ($HOSTS) are down (ping failed) at $(date)"
fi
