Requirements: Use shell to customize various personalized alarm tools, but need unified management and standardized management.
Ideas: Specify a script package, including the main program, subprograms, configuration files, mail engine, output log, etc.
Main program: As the entrance of the whole script, it is the lifeblood of the whole system.
Configuration file: It is a control center, which is used to switch each subprogram and specify each associated log file.
Subroutine: This is the real monitoring script, which is used to monitor various indicators.
Mail engine: It is implemented by a python program, which can define the server that sends the mail, the sender and the sender's password
. Output log: The entire monitoring system must have log output.
Requirements: Our machines have various roles, but the same monitoring system must be deployed on all machines, which means that no matter what the role of all machines, the entire program framework is the same. The difference is that different customizations are made according to different roles. configuration file.
Program structure: 
under bin is the main program
conf under the configuration file
share under the various monitoring scripts
mail under the mail engine
log under the log.

##定义QQ邮箱的账号和密码，你需要修改成你自己的账号和密码（请不要把真实的用户名和密码放到网上公开
，否则你会死的很惨）

#####脚本使用说明######
#1. 首先定义好脚本中的邮箱账号和密码
#2. 脚本执行命令为：python mail.py 目标邮箱 "邮件主题" "邮件内容"To be continued. . . . . .
