查看CPU使用率

rem 如果wmi服务(服务名为Winmgmt）坏掉了，需要到system32webm目录下执行如下注释的命令

rem for %i in (*.dll) do RegSvr32 -s %i
rem Regsvr32 -s scrcons.exe
rem Regsvr32 -s unsecapp.exe
rem Regsvr32 -s wbemtest.exe
rem Regsvr32 -s WinMgmt.exe
rem Regsvr32 -s WmiApSrv.exe
rem Regsvr32 -s WmiPrvSE.exe

@echo off
@echo On Error Resume Next>temp.vbs
@echo.>>temp.vbs
@echo dim iCpuUsePercentage>>temp.vbs
@echo dim objFileStream>>temp.vbs
@echo dim objTextFileWriter>>temp.vbs
@echo Set objProc = GetObject("winmgmts:\.
ootcimv2:win32_processor='cpu0'")>>temp.vbs
@echo iCpuUsePercentage=objProc.LoadPercentage>>temp.vbs
@echo set objFileStream =CreateObject("Scripting.Filesystemobject")>>temp.vbs
@echo set objTextFileWriter=objFileStream.opentextfile("log.tmp",8,True)>>temp.vbs
@echo objTextFileWriter.WriteLine(iCpuUsePercentage)>>temp.vbs
@echo objTextFileWriter.close>>temp.vbs
start temp.vbs
ping -n 3 127.0.0.1 >nul
del %~dp0temp.vbs
@echo CPU占用率：
type log.tmp
pause
del %~dp0log.tmp

使用wmic记录CPU使用率，每隔一秒记录一次，记录到日志中。并打印出对应的时间。将批处理内容保存为.bat文件执行即可。其中的执行次数1000000可以自行修改，比如运行24小时的话，可以修改为24*3600.

@echo off
set log=%~dp0cpu%date%.log
for /L %%i in (0,1,1000000) do (
wmic os get localdatetime /value>>%log%
wmic cpu get loadpercentage /value /every:1 /repeat:1>>%log%
)

set log="%~dp0network%date%.log"
