performancecounter

I'm trying to register a performance counter and part of this process includes adding some textual descriptions to a specific registry key. For English this key is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009 which apparently is also known as HKEY_PERFORMANCE_TEXT. There are a pair of values under there (Counter, Help) that have REG_MULTI_SZ data, and I need to modify them to accomplish my goal. The official way of doing this is by using a tool called lodctr along with a .h and .ini file . There is also a function for doing this programmatically , but my

Im using messageInspectors in my WCF service to measure elapsed time on each service method like this : public void AfterCall(string operationName, object[] outputs, object returnValue, object correlationState) { if (_activated) { _startTime.Stop(); PerformanceCounterHandler.Instance.SetAveragePerformanceCounter(operationName, _startTime.ElapsedTicks); } } public object BeforeCall(string operationName, object[] inputs) { Guid correlationState; if (_activated) { correlationState = Guid.NewGuid(); _startTime = new Stopwatch(); _startTime.Start(); return correlationState; } return null; } This is

Summary Consider the following loop: loop: movl $0x1,(%rax) add $0x40,%rax cmp %rdx,%rax jne loop where rax is initialized to the address of a buffer that is larger than the L3 cache size. Every iteration performs a store operation to the next cache line. I expect that the number of RFO requests sent from the L1D to the L2 to be more or less equal to the number of cache lines accessed. The problem is that this seems to be only the case when I count kernel-mode events even though the program runs in user-mode, except in one case as I discuss below. The way the buffer is allocated does not seem

When I create and use performance counters like this: private readonly PerformanceCounter _cpuPerformanceCounter; public ProcessViewModel(Process process) { _cpuPerformanceCounter = new PerformanceCounter("Process", "% Processor Time", process.ProcessName, true); } public void Update() { CPU = (int)_cpuPerformanceCounter.NextValue() / Environment.ProcessorCount; // Exception } ... I get an exception Instance 'Name of instance' does not exist in the specified Category and don't understand why. P.S. Code <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.net> <settings>

Hi, I have a WCF service in IIS7 that communicates with a winform application over TCP(WAS), now I need to monitor the performance. I have added this to the web.config file: <system.serviceModel> <diagnostics performanceCounters="All" /> After opening the Performance Monitor I run a couple of tests with my winform to make sure that the service is activated. I then open the Performance Monitor (live), right click and add counters. I expand the ServiceModelService 4.0.0.0 and select Calls and Calls Duration, I also select my service(svc) that is stated in the Instance of selected object listbox

I found many sources to get the cpu usage of each process. in general there are many ways to get the cpu usage of process . percentprocessortime from win32_perfformatteddata_perfproc_process performancecounter class in system.diagnostics by manual calculation Process class (by process.getcurrentprocess().totalprocessortime;) as said in here . FirstWay: For the remote process monitoring(my scenario is remote monitoring), the percentprocessortime always shows value 0 to 100+. this 100+ happens because of multiple processors in a system. it can be calculated by using percentprocessortime/

I am trying to learn how to monitor the network bandwidth usage of a specific application. I am looking at IPv4InterfaceStatistics , but that seems to monitor an NIC card's performance. I'd like to monitor a specific application to see how much bandwidth is consumed every second. Does anyone know of an example of how this can be done? using System; using System.Diagnostics; using System.Globalization; using System.IO; using System.Net; using System.Net.Sockets; using System.Reflection; using System.Text; using System.Threading; namespace ConsoleApplication2 { class Program { static void Main
