01. 概括1.0 脚本更新地址
Git更新地址：shell_monitor_script.sh
文章原文地址：使用shell脚本监控少量服务器并发送微信告警信息
1.1 前提：
平台系统：linux系统下
接收信息：微信企业号
1.2 脚本说明
需要修改微信接口
脚本对应参数的修改：包括IP，告警阈值等
1.3 脚本使用
该脚本监控包括Disk、CPU、MEM、LOAD等主机资源，以及docker服务和docker容器。
将该脚本附件假定放于：/home/mai/.check_host.sh。
那么在定时任务上可以增加定时任务：
$ echo "## 每分钟执行监控脚本一次" | sudo tee -a /etc/crontab
$ echo "*/1 * * * * mai bash /home/mai/.check_host.sh" | sudo tee -a /etc/crontab
