Monitor server status 监控服务器的活动状态

1. 监控服务器的活动状态

#!/bin/bash
 ip=127.0.0.1
while true
 do
  ping -c1 $ip>/dev/null 2>/dev/null
  if [ $? == "0" ];then
  echo "`date "+%Y-%m-%d %H:%M:%S "`$ip is up">>a.log
  fi
  sleep 1
done








写一个工具，对 127.0.0.1 持续监控，当网络断开时，记录时间信息、状态信息到/tmp/a.log

#!/bin/bash
 ip=192.168.1.133
while true
 do
  #ping -c10 $ip>/dev/null 2>/dev/null
  NUM=`ping -c1 $ip | grep -i Unreachable | wc -l`
  if [ $NUM == "1" ];then
 
  echo "`date "+%Y-%m-%d %H:%M:%S "`$ip is down">>/tmp/a.log
  else
  echo "`date "+%Y-%m-%d %H:%M:%S "`$ip is up"
  fi
  sleep 1
done
