performance counter problem

[Dirk Reske]

Hello,

I have following code:

 

[Dirk Reske]

sorry...

following code:
PerformanceCounterCategory cat = new PerformanceCounterCategory("Process");

foreach (string instance in cat.GetInstanceNames())
{
PerformanceCounter counter = new PerformanceCounter("Process","%
Processor Time",instance);
this.listBox1.Items.Add(instance + ":" + counter.NextValue());
}

why does counter.NextValue() allways returns 0??

...

foreach (string instance in cat.GetInstanceNames())
{
PerformanceCounter counter =
new PerformanceCounter("Process","%Processor Time",instance);
this.listBox1.Items.Add(instance + ":" + counter.NextValue());
}

why does counter.NextValue() allways returns 0??

"If the calculated value of a counter depends on two counter reads, the
first read returns 0.0." [from documentation]

Perhaps you're really looking for counter.RawValue?

running process?
Its in the PerformanceCounter Category "Process"
