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：

while (hld == 0 and count<20):

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

time.sleep(0.5)

#wnd = win32ui.GetForegroundWindow()

#print wnd.GetWindowText()

hld = win32gui.FindWindow(None,label)

print("hld is %s" % hld)

print("pwin is %s" % pwin)

print pwin.GetWindowText()

print("click...")
