Shell-written alarm count control and recovery sample code

I am also a newbie. I am a little old-fashioned. I am a good trainer. It is a reference for beginners. Copy codeThe 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
# Sending a Fault Elimination Short Message notification -- calling insert_table
Messages = "$ host server resume normal 'date" + % Y % m % d % H: % M: % S "'"
Echo "$ messages">./log/ping_err_recover.log
Insert_table
Else
Echo "the detection result ----> $ host server ping detection is normal"
Echo "'date" + % Y % m % d % H: % M: % S "'---> $ host server ping check normal, ping times $ ping_count, receive $ succ_ping ">>. /log/ping_log
Fi
Else
Echo "This detection result ----> $ the host server has packet loss. The packet loss rate is: $ loss_ping"
Messages = "'date" + % Y % m % d % H: % M: % S "'---> $ the host server has packet loss. The packet loss rate is $ loss_ping"
# Handle the number of alerts. If the number of alerts exceeds 2, no alert is triggered.
# Host a (number of alerts)
# Increase the number of alerts by 1
Echo "the alarm server is $ host"
If [-f./alarm_file/alarm _ $ host]; then
# Retrieve the current Alert 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 "no text message is sent more than twice"
Echo "'date" + % Y % m % d % H: % M: % S "'---> $ the host server receives $ succ_ping due to packet loss. The packet loss rate is: $ loss_ping. If it exceeds the limit, it is not sent again. ">./Log/ping_err_log
Else
# No more than two calls to the insert_table function to send text messages
Echo "no more than 2 times"
Echo "'date" + % Y % m % d % H: % M: % S "'---> $ the host server receives $ succ_ping due to packet loss. The packet loss rate is: $ loss_ping ">>. /log/ping_err_log
Insert_table
Fi
Else
# First Alert
Echo "first alarm"
Echo "$ host 1">./alarm_file/alarm _ $ host
Insert_table
Echo "'date" + % Y % m % d % H: % M: % S "'---> $ the host server receives $ succ_ping due to packet loss. The packet loss rate is: $ loss_ping ">>. /log/ping_err_log
Fi
Fi
