A goal is a dream with a deadline. Much effort, much prosperity.
Configuring Server Monitoring Leased Network
Project Introduction:
Configure a server to monitor the status of the private line network, (due to the company's business, the private line needs to be used to connect with customers) real-time monitoring of the status of the private line, and alarm if the private line fails
Alarm methods include email alarm, WeChat alarm, and monitor alarm, etc.
The email alarm built by the company is to write a script to monitor whether the network is unobstructed. If it fails, send an email to the alarm directly. It is more direct and convenient. Compared with the traditional monitor monitoring services (zabbix, nagios, cacti, etc.), it is more intuitive, (personal opinion) After all, the dedicated line network is very important! WeChat alarm is more cumbersome and more troublesome, and it needs to call the interface of WeChat or something.
Project preparation:
A server, because only one script needs to run, does not take up much resources, it can be placed on other servers (such as test servers, log servers, monitoring servers, etc. to avoid production servers as much as possible) Because the project has been deployed, I am here on a virtual machine Perform restore steps

Script monitoring Script:
The composition of the script consists of 4 files
Among them, wss.sh is the main script program, and the other three components are called by the main program
Component Description:
ip.txt is the monitored private line IP address divided into two columns, one is IP and the other is alias
mima.txt is the sender's mailbox password (IMAT/SMTP password) and can be encrypted by other programs
sou.txt is the recipient's mailbox, the alarm will send a copy to all mailboxes in this file
wss.sh is the main program, used to monitor the dedicated line, peer IP or host, call the other three files, and alarm when abnormal

配置服务器监控专线网络
项目介绍：
配置一台服务器监控专线网络的情况，（由于公司业务的原因需要用到专线进行与客户对接）实时监控专线的状态，如果专线不通则进行报警
报警方法有邮件报警，微信报警，和监控器报警等
公司搭建的邮件报警就是写脚本进行监控网络是否通畅，不通则直接发邮件进行报警，更直接，更方便相比传统的监控器监控服务（zabbix、nagios、cacti等）更直观，（个人意见）毕竟专线的网络是挺重要的！微信报警则就显得比较繁琐更麻烦还需要调用微信的接口什么的
项目准备：
一台服务器，因为只有一个脚本需要跑占用的资源不大，可以放在其他服务器上（比如测试服务器，日志服务器，监控服务器等尽量避开生产服务器）因为项目已经部署，我这里在虚拟机上进行还原步骤

脚本监控Script：
脚本的组成有4个文件
其中wss.sh为主脚本程序，其他三个为主程序调用的组件
组件说明：
ip.txt 为监控的专线IP地址分为两列，一列为IP，一列为别名
mima.txt 为发件人的邮箱密码（IMAT/SMTP密码）可用其他程序进行加密
sou.txt 为收件人的邮箱，报警则会向此文件里的所有邮箱发一份
wss.sh 为主程序，用于监控专线，对端IP或主机，调用其他三个文件，异常报警
