windows中有什么命令可以监控进程所占用的CPU和内存呢？

[speeper]

我希望通过脚本或者命令自动记录一段长期的CPU使用率和内存占用率，不是通过任务管理器来看。谢谢各位啦。

这个用wmi来实现正合适,现在喜欢上了js,所以就不用vbs了，给你个js的自己改了用吧:

var oFSO = new ActiveXObject("Scripting.FileSystemObject");
var oFile = oFSO.OpenTextFile("a.txt",2,true);
var oWMI = GetObject("Winmgmts:");
var oRefresher = new ActiveXObject("WbemScripting.SWbemRefresher");
var oMemory = oRefresher.AddEnum(oWMI,"Win32_OperatingSystem").ObjectSet;
var oProcessor = oRefresher.AddEnum(oWMI,"Win32_Processor").ObjectSet;
var oProcess = oRefresher.AddEnum(oWMI,"Win32_Process").ObjectSet;
do
{
    oRefresher.Refresh();

    var s = "";
    var oTime = new Date();
    var colMemory = new Enumerator(oMemory);
    var colProcessor = new Enumerator(oProcessor);
    var colProcess = new Enumerator(oProcess);

    s += "纪录时间:\t\t";
    s += oTime.toLocaleString() + ":" + oTime.getMilliseconds() + "\r\n";
    s += "CPU使用率:\t";
    s += colProcessor.item().Loadpercentage + 1 - 1 + "%\r\n";
    s += "可用内存:\t\t";
    s += colMemory.item().FreePhysicalMemory  +"KB\r\n";
    s += "进程列表:\r\n";
    for(;!colProcess.atEnd();colProcess.moveNext())
    {
        s += colProcess.item().Name +"\r\n"
    }
    s += ";**********************************************************\r\n";
    oFile.Write(s);
    WScript.Sleep(200);
}while(true);

如果不想用*.js或*.vbs,也可以让wmic来完成:

@echo off

for /f "delims=" %%i in ('wmic path win32_processor get loadpercentage /value') do set "%%i" >nul
for /f "delims=" %%i in ('wmic path win32_operatingsystem get freephysicalmemory /value') do set "%%i" >nul
echo CPU使用率:        %loadpercentage%%%
echo 可用内存:         %freephysicalmemory%KB
echo 进程列表:
wmic path win32_process get name
pause

使用wmic的get,还可以带上/every:1,表示每1秒查询一次，直到按下任意键停止,可惜交互性不够友好,如果你对格式并没有什么特别的要求的话也可以直接>>xxx.log wmic path win32_xxx get xxx /every:1来纪录每秒的变化。

系统自带的性能监视器不就是用来干这个的么
