Chapter 3 Appendix
In the case of the sample result above, the data appears at the second paragraph and you can know that the
intake air temperature is 27
°
C.
3.1.3
Processor utilization
The utilization rate of all logical processors is given from the Win32_PerfFormattedData_PerfOS_Processor
class of WMI.
Here is the sample file created by using Visual Basic Script. This sample outputs the processor utilization rate
every 30 seconds.
' Start Script
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!
\\
" & strComputer & "
\
root
\
cimv2")
set objRefresher = CreateObject("WbemScripting.Swbemrefresher")
Set objProcessor = objRefresher.AddEnum _
(objWMIService, "Win32_PerfFormattedData_PerfOS_Processor").objectSet
objRefresher.Refresh
Dim first
first = true
Do
For each intProcessorUse in objProcessor
If first Then
If intProcessorUse.Name = "_Total" Then
first = false
End If
else
Wscript.Echo "Proc" & intProcessorUse.Name & " : " & _
"PercentProcessorTime=" & _
intProcessorUse.PercentProcessorTime
End If
Next
Wscript.Sleep 30*1000 'sleep 30 * 1000ms
objRefresher.Refresh
Loop
' End Script

Execution example
C:

VBS> cscript //nologo Proc.vbs
•
Execution result
Proc0 : PercentProcessorTime=0
Proc1 : PercentProcessorTime=0
Proc2 : PercentProcessorTime=0
Proc3 : PercentProcessorTime=0
Proc4 : PercentProcessorTime=76
Proc5 : PercentProcessorTime=0
Proc6 : PercentProcessorTime=0
Proc7 : PercentProcessorTime=0
Proc_Total : PercentProcessorTime=9
Proc 0
to
Proc 7
show the utilization rate of each processor while
Proc_Total
shows the total processor
utilization rate.
