Python3監(jiān)控windows,linux系統(tǒng)的CPU、硬盤、內存使用率和各個端口的開啟情況詳細代碼實例

這篇文章主要介紹了Python3監(jiān)控windows,linux系統(tǒng)的CPU、硬盤、內存使用率和各個端口的開啟情況詳細代碼實例,需要的朋友可以參考下

由于項目的需要，需要做一個簡單監(jiān)控服務器的CPU利用率、CPU負載、硬盤使用率、內存利用率和服務器的各個端口的開啟情況的程序，并把結果通知到監(jiān)控平臺，如果出現異常，監(jiān)控平臺打電話或者發(fā)短信通知給具體的運維人員

python版本要求：python3.0 以上

安裝 python 的 psutil 包和 requests 包

pip install psutil

pip install requests

Linux系統(tǒng)下運行效果

Windows系統(tǒng)下運行效果
