This article mainly shows you "how to achieve the shell of ping discovery and swap alarm", which is easy to understand and clear. I hope it can help you solve your doubts. Here, let me lead you to study and learn "how to realize the shell of ping discovery and swap alarm".

The code is as follows:

#! / 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-Flowers' {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

Copy the above to add ping.sh to crontab and let it run once every 10 minutes, and the email program is mutt.

The following is a supplement:

Linux's and solaris's are not the same!

The code is as follows:

#! / 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 my email
