This article is about how to use shell to write alarm control and recovery content. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

The code is as follows:

#!/ bin/bash

if [ $succ_ping -gt $((ping_count-1)) ];then

if [ -f ./ alarm_file/alarm_$host ];then

rm -rf ./ alarm_file/alarm_$host

#Send troubleshooting SMS notification--invoke insert_table

messages="$host server communications restored `date "+%Y%m%d %H:%M:%S"`"

echo "$messages" >>./ log/ping_err_recover.log

insert_table

else

echo "This detection result--->$host Server ping detection normal"

echo "`date "+%Y%m%d %H:%M:%S"`--->$host Server ping detected OK,ping count $ping_count, receive $succ_ping" >./ log/ping_log

fi

else

echo "This detection result--->$host server has packet loss phenomenon, packet loss rate is:$loss_ping"

messages="`date "+%Y%m%d %H:%M:%S"`--->$host Server has packet loss, packet loss rate:$loss_ping"

#Deal with the number of alarms, more than 2 times will not alarm

#format host a(alarm times)

#Number of times alarms have occurred plus 1

echo "Alert server is $host"

if [ -f ./ alarm_file/alarm_$host ];then

#Take the current alarm count and add 1

a=`awk '{print$2}' ./ alarm_file/alarm_$host`

b=$(($a+1))

echo "$host $b" >./ alarm_file/alarm_$host

alarm_count=`awk '{print$2}' ./ alarm_file/alarm_$host`

if [ $alarm_count -gt $sms_count ];then

echo "Do not send SMS more than 2 times"

echo "`date "+%Y%m%d %H:%M:%S"`--->$host Server has packet loss phenomenon, received $succ_ping, packet loss rate:$loss_ping, more than two times will not be sent. " >>./ log/ping_err_log

else

#No more than 2 calls to insert_table function to send SMS

echo "Not more than 2 times"

echo "`date "+%Y%m%d %H:%M:%S"`--->$host Server has packet loss, received $succ_ping, packet loss rate:$loss_ping">>./ log/ping_err_log

insert_table

fi

else

The first alarm

echo "First alarm"

echo "$host 1" >./ alarm_file/alarm_$host

insert_table

echo "`date "+%Y%m%d %H:%M:%S"`--->$host Server has packet loss, received $succ_ping, packet loss rate:$loss_ping" >>./ log/ping_err_log

fi

fi

done
