本文实例为大家分享了python监控进程脚本的具体代码，供大家参考，具体内容如下

原理：

监控一个指定进程，每隔5秒钟获取其CPU、内存使用量超过60%即kill掉该进程，获取其句柄数，超过300也kill掉该进程

运行环境是windows 64位系统+python 2.7 64位 ，这里需要使用到psutil 类库，要另外安装。脚本里面可以自动安装，前提是你已经下载好了安装包psutil-3.3.0.win-amd64-py2.7.exe

下面看代码：

 #print ("os type: %s " % type)

 print("the setup is no running,will run it...")

 print("sleep 1 seconds...")

 #print wnd.GetWindowText()
