#####Script Instructions######
#1. First define the email account and password in the script#2. The script execution command is: python mail.py Create
target mailbox "mail subject" "mail content"
Mail engine configuration file
#This script is used for alarm convergence
#Written by Adai
log=$1
t_s= #Timestamp date +%s
1
t_s2 = #Timestamp date -d "2 hours ago" +%s

purpose of defining this timestamp is to ensure that the script is executed for the first time When v is greater than one hour
#guarantee the alarm when it is executed for the first time
#Because the script will only be executed when a failure occurs, so the first execution must be alarmed

a log file that records timestamps

time between two timestamps

the time interval is greater than 1 hour, start the alarm
