上次发了一个单机版的主机状态监控程序(https://www.52pojie.cn/thread-1680459-1-1.html)
这次来个网络版本的.
linux 和 windows 版本任意搭配.
只需要有一个server端用来接收client发送的消息就可以了。
运行截图.jpg
功能
server 端
启动 server 端, 监听指定端口, 生成状态信息页面.
发现接收到的状态信息中达到阈值,发送钉钉报警通知.
Usage of ./server_linux: -p string 监听端口,默认8080 (default "8080")root@test:~/run/server# ./server_linux -p 802022/09/06 06:49:39 服务已启动,监听端号 :80client 端
给server 定时发送主机状态信息.
./client_linux -s "http://127.0.0.1:80"源码:
