How to implement a ping detection alarm function

This article mainly introduces how to achieve a ping detection alarm function, the article introduces in great detail, has a certain reference value, interested friends must read it!

The code is as follows:

#! / bin/bash

Ping_monitor ()

{

Host_= (203 204 205 207 208 209 210 212 213 214 215 216 217 218 219 220 221)

Ping_count=3

Called= (13000000001 130000002 130000003)

Calling=13000000000

Callop=1310000000

# main

Echo "`date" +% Y%m%d% H:%M:%S "`- > script starts execution." > > ping_log

For host_1 in ${host_ [*]}; do

Host=192.168.1.$host_1

Echo "- > start to check whether the communication of $host server is normal, and the number of ping times $count"

Ping_result= `ping $host-c $ping_count | tail-2 | head-1`

# sleep 1

Echo "- > Server $host detection completed"

# take the number of successful messages

Succ_ping= `echo ${ping_result:23:1} `

# take the percentage of failure

Loss_ping= `echo ${ping_result:46:4} `

If [$succ_ping-eq $ping_count]; then

Echo "this test result-> $host server ping test is normal"

Echo "`date" +% Y%m%d% H:%M:%S "`--> $host server ping detection is normal" > > ping_log

Else

Echo "results of this test-> $host server has lost packets, and the packet loss rate is: $loss_ping"

Echo "`date" +% Y%m%d% H:%M:%S "`--> $host server has lost packets. The packet loss rate is $loss_ping" > > ping_err_log.

# insert SMS list-smssend00

For called in ${telno [*]}; do

Mysql-h$dbhost-u$dbuser-p$dbpass-D$dbbase > ping_log

}
