测试机房网络连通性和延迟(shell脚本)
一、生成本机房到各电信、联通、移动、教育网ping和traceroute的数据；另外搜集各个运营商ip全国的ip列表文件为ip.txt;ipedu.txt;ipdx.txt;ipcmcc.txt(移动)
脚本一:
#!/bin/bash
ping -c 100 $1 > test/temp/temp_$1
tail -n 3 test/temp/temp_$1
traceroute $1
脚本二:做任务计划每隔15分钟执行一次:
#!/bin/bash
DateTime=`date "+%Y%m%d%H%M"`
Date=`date "+%Y%m%d"`
cd ~
mkdir -p test/temp
mkdir -p test/${Date}/wt
mkdir -p test/${Date}/dx
mkdir -p test/${Date}/edu
mkdir -p test/${Date}/cmcc
while true; do
read iplist || break ;
sh ping_tr.sh $iplist >> test/${Date}/wt/$iplist${DateTime}.txt &
done < ip.txt
while true; do
read iplist || break ;
sh ping_tr.sh $iplist >> test/${Date}/edu/$iplist${DateTime}.txt &
done < ipedu.txt
while true; do
read iplist || break ;
sh ping_tr.sh $iplist >> test/${Date}/dx/$iplist${DateTime}.txt &
done < ipdx.txt
while true; do
read iplist || exit ;
sh ping_tr.sh $iplist >> test/${Date}/cmcc/$iplist${DateTime}.txt &
done < ipcmcc.txt
二、生成数据报告，发邮件到系统运维部
