掉包报警 ping发现掉包报警的shell代码
人气:0想了解ping发现掉包报警的shell代码的相关内容吗，在本文为您仔细讲解掉包报警的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：掉包报警，下面大家一起来学习吧。
复制代码 代码如下:
#!/bin/bash
PING=`which ping`
DATE=`date +%Y%m%d%H%M`
TAIL=`which tail`
LOG=./ping$DATE.log
HOSTS="selboo.com.cn 221.130.191.97"
COUNT=200
for myHost in $HOSTS
do
count=$(ping -c $COUNT $myHost | grep ‘loss' | awk -F',' '{ print $3 }' | awk -F “%” ‘{ print $1 }')
if [ $count -ge 10 ]; then
/bin/echo selboo | mutt -s "$myHost pingispacketloss>10% $DATE" root@selboo.com.cn
fi
done
exit 0
复制上以上内容为ping.sh加入crontab中让其10分钟跑一次，其中发邮件程序为mutt
以下是补充：
linux 的和solaris的居然不一样！
复制代码 代码如下:
#!/bin/sh
PingConf='/opt/monitor/newIp'
#File where the log will be stored
LogDir='/opt/monitor/newLog'
#Define the interval time
INTERVAL='10'
#Define the alarm process
########################################################
proc_main()
{
while read IpAddress
do
#ingore any hash signs
case $IpAddress in
#*);;
*)
ping -w 20 $IpAddress -c 5 >errtmp$$
# ping $IpAddress -c 10 >errtmp$$
if [ $? = 0 ] ; then
rm errtmp$$
else
rm errtmp$$
ErrTime=`date +%Y/%m/%d/%H:%M:%S`
# echo "$ErrTime"": ""$IpAddress"" cann't be connected">>$LogDir
echo "$ErrTime"":""$IpAddress"" cann't be connected
">>$LogDir
sleep 1
cp /opt/monitor/newLog /opt/OV/www/htdocs/PingLog/new.html
sleep 1
# mail -s "$IpAddress"Cantreach -c 我的email </dev/null
play -v 50 /opt/monitor/123.au
fi
esac
done <$PingConf
}
##########################################################
# execute the proc_main function every the specified time INTERVAL
while [ "1" -eq "1" ]
do
# execute the proc_main function
proc_main
# suspend execution for INTERVAL seconds
sleep $INTERVAL
done
