Shell Project-Alarm system

Requirements: Use the shell to customize a variety of personalized alarm tools, but the need for unified management, standardized management.
Idea: Specify a script package that contains the main program, subroutine, configuration file, mail engine, output log, and so on.
Main program: As the entire script portal, is the lifeblood of the entire system.
Configuration file: is a control center that uses it to switch individual subroutines, specifying each associated log file.
Subroutine: This is the real monitoring script, used to monitor each indicator.
Mail Engine: It is implemented by a Python program that defines the server to which the message is sent, the person who sent it, and the sender's password
Output log: The entire monitoring system should have a log output.
Requirements: Our machine roles are varied, but the same monitoring system is deployed on all machines, and the entire program framework is consistent, regardless of the role of all machines, depending on the role of the different configuration files.
Program Architecture:

Under Bin is the main program
Conf is the configuration file
Share is the various monitoring scripts
Mail engine under Mail
Log is the journal.
