Re: Got CPU Load incorrectly using script

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

thanks for your reply, but it is about two scripts. Only one script, it
returns normal value (or appears resonable).

but if run another after one, checkcpu.vbs first, checkmem.vbs got error
80041010 (but run chekmem.vbs only won't get error );

if checkmem.vbs first, checkcpu.vbs will not get error, but got unresonable
value of 100% all the time.

the scripts are very simple, so I think


'============checkcpu.vbs===============
strComputer = "."
Set objWMIService = GetObject("winmgmts:" &
"{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set wbemObjectSet = objWMIService.ExecQuery("Select * from
Win32_Processor",,48)
For Each wbemObject In wbemObjectSet
wscript.echo wbemObject.LoadPercentage
next
wscript.echo "0"
wscript.echo ""
wscript.echo ""
,=================end=====================

'============checkmem.vbs================
strComputer = "."
Set objWMIService = GetObject("winmgmts:" &
"{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set wbemObjectSet = objWMIService.ExecQuery("select * from
Win32_PerfFormattedData_PerfOS_Memory")
For Each wbemObject In wbemObjectSet
wscript.echo wbemObject.PercentCommittedBytesInUse
next
wscript.echo "0"
wscript.echo ""
wscript.echo ""
,=======================================
