linux应该有很多方法可以获取进程的cpu和内存信息,但windows貌似之前接触的是psutil,后来查了一些资料发现wmi也能够获取进程的信息,但貌似效率不太高,应该可以做监控等性能要求不太高的情况
下载wmi,这个网上很多方法和途径,我是用easyinstall来安装,这个不详细说明了
直接附上代码:
import wmi from win32com.client import GetObject import win32gui,time mywmi = GetObject("winmgmts:") # allProcess = mywmi.ExecQuery("select * from Win32_Process") # for i in allProcess: # pid = i.Properties_("ProcessID") # print pid # network = mywmi.ExecQuery("select Processor, _Total, Processor Time from PerformanceCounter") # print network # for i in network: # print i.Properties_("Processor") mywql= mywmi.ExecQuery("SELECT * FROM Win32_PerfFormattedData_PerfProc_Process where PercentPrivilegedTime>10") def getPrcessInfo(wql): while 1: for j in wql: #print j.Properties_("PercentPrivilegedTime").__int__() ##print j.Properties_("name").__str__()+" "+j.Properties_("IDProcess").__str__()+" "+j.Properties_("PercentPrivilegedTime").__str__() if j.Properties_("name").__str__()!= "_Total" and j.Properties_("name").__str__()!="Idle": print j.Properties_("name") print j.Properties_("PercentPrivilegedTime").__int__() print j.Properties_("WorkingSet").__int__() time.sleep(1) #return 1 #break ##print ":)" getProcessInfo(mysql)
编码方式停留在初学的基础上,后续需要改进,j.Properties_("属性")得出的是一个实例,所以需要转换成相应的格式;
详细的属性可以参考https://msdn.microsoft.com/en-us/library/aa394277(VS.85).aspx
个人感觉wmi功能挺强大的,能搞通的话,应该可以玩转windows(有点夸张了)
