    Hello,

    due to performance issues a control computer at a manufacturing plant we have to Monitor some Parameters of the Memory Management, so also the page faults per second. We try to do it like this

               

    PerformanceCounterpcPageFaultsSec = newPerformanceCounter("Memory", "Page Faults/sec");

    dPageFaultsSec =  pcPageFaultsSec.NextValue();

    textBoxPageFaultsSec.Text = dPageFaultsSec.ToString("0.0");

    But here we always get a value of Zero, although perfmon Shows values not equal zero.

    What's wrong ?

    Hi Gerhard,

    you will have to query the value more than once, use a loop to get some results:

            private void PerformancePageFaults()
        {
            PerformanceCounter pageFaultsSec = new PerformanceCounter("Memory", "Page Faults/sec");

            for (int index = 0; index < 10; index++)
            {
                Console.WriteLine($"Page Faults/sec {pageFaultsSec.NextValue()}");
                System.Threading.Thread.Sleep(1000);
            }
        }

    As a sample result:

    Page Faults/sec 0
Page Faults/sec 799,3115
Page Faults/sec 740,2796
Page Faults/sec 300,9994
Page Faults/sec 1076,908
Page Faults/sec 626,9908
Page Faults/sec 475,5057
Page Faults/sec 650,9771
Page Faults/sec 830,4797
Page Faults/sec 279,9876
