How to fetch CPU Usage from DOT Net

Re: How to fetch CPU Usage from DOT Net

Hi Vijay,

You need to use one of the Performance Counters:

Imports System.Diagnost ics

Dim oPerf1 As New PerformanceCoun ter

oPerf1.Category Name = "Processor"
oPerf1.CounterN ame = "% Processor Time"
oPerf1.Instance Name = "0"

Dim I As Integer
For I = 0 To 100
SomeListBox.Ite ms.Add (oPerf1.NextVal ue)
Threading.Threa d.Sleep (20)
Next

Regards,
Fergus

ps. You posted to a lot of groups there. I'm not sure how relevant this
question is to ADO and ASP.??

Re: How to fetch CPU Usage from DOT Net

You can use the System.Diagnost ics.Performance Counter class. The
PerformanceCoun ter component can be used for both reading existing
predefined or custom counters and writing performance data to custom
counters.
This sould get you started:

Dim myCounter As System.Diagnost ics.Performance Counter = New
System.Diagnost ics.Performance Counter()

myCounter.Categ oryName = "Processor"
myCounter.Count erName = "% Processor Time"
myCounter.Insta nceName = "_Total"
MessageBox.Show (myCounter.Next Value().ToStrin g()) 'cpu usage

Cheers,

Actually, this is a fairly responsible group of groups for a novice dotnet'r
to query (with the exception of the adonet...). And you got a 'general'
answer. Using the Web Matrix supplied Matrix ClassBrowser (free Web Matrix
download from Microsoft!) it took more time for the ClassBrowser to load
than to find the answer to this question.

However, a "way to get the exact CPU Usage" is excluded by the Heisenberg
uncertainty principle (http://www.aip.org/history/heisenberg/p01.htm)! Do
not despair... what you can get is:

AverageBase
AverageCount64
AverageTimer32
CounterDelta32
CounterDelta64
CounterMultiBas e
CounterMultiTim er
CounterMultiTim er100Ns
CounterMultiTim er100NsInverse
CounterMultiTim erInverse
CounterTimer
CounterTimerInv erse
CountPerTimeInt erval32
CountPerTimeInt erval64
ElapsedTime
NumberOfItems32
NumberOfItems64
NumberOfItemsHE X32
NumberOfItemsHE X64
RateOfCountsPer Second32
RateOfCountsPer Second64
RawBase
RawFraction
SampleBase
SampleCounter
SampleFraction
Timer100Ns
Timer100NsInver se

Hi Per,

Lol.
If ever there's a way round that there'll always be the Windows OS
uncertainty principle.

|| AverageBase
|| AverageCount64
||
|| Timer100Ns
|| Timer100NsInver se

These are all PerformanceCoun ter data types.

If you have Server Explorer in your VS, you can get a list of the actual
counters by opening this window, and expanding the nodes for Servers and your
machine.

There is also a Management Console application, Perfmon.exe, with which
you can examine the available counters.
