performancecounter

问题 I am following the answer here: Calculating Bandwidth And implemented everything like he said. My monitor is initialized like so: netSentCounter.CategoryName = ".NET CLR Networking"; netSentCounter.CounterName = "Bytes Sent"; netSentCounter.InstanceName = Misc.GetInstanceName(); netSentCounter.ReadOnly = true; I can corrently see that Misc.GetInstanceName() returns "MyProcessName[id]". However I keep getting the exception that the instance doesn't exist in the specified category. My

问题 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

问题 I am trying to get the % of total CPU usage to a label1.Caption I've searched and found these: didn't work - http://www.vbforums.com/showthread.php?345723-DELPHI-Get-CPU-Usage not what I need - http://delphi.cjcsoft.net/viewthread.php?tid=42837 also found bunch of solutions regarding calculating the Usage per process but that is not what i am looking for , i just want the total CPU usage like this widget : this is what i am working on : I believe there is a simple way like when we get RAM

问题 Shark, Apple's profiler which let you configure custom performance counters, is no longer supported in OSX Mountain Lion since it can't run a 32-bit kernel. Instruments.app, Apple's replacement for Shark, doesn't seem to support reading performance counters such as L1 cache hits/misses**. Is there anyway to actually setup and read performance counters on OS X? Even if there is no application, is there some user-land API to do this? **Instruments.app does seem to have an interface for

问题 The performance counters are working, but their data is not logged inside WADPerformanceCountersTable. In the webrole.cs I have public override bool OnStart() { var config = DiagnosticMonitor.GetDefaultInitialConfiguration(); config.PerformanceCounters.DataSources.Add( new PerformanceCounterConfiguration { CounterSpecifier = @"\Processor(_Total)\% Processor Time", SampleRate = TimeSpan.FromSeconds(5) }); if (!PerformanceCounterCategory.Exists("MyCustomCounterCategory")) {

问题 I am looking for counters in Linux systems similar to custom counters in Windows, which could be accessed through C#. (http://msdn.microsoft.com/en-us/library/aa326924%28v=vs.71%29.aspx). My use case is this: I have a process that imports a file from location A to B. This file has some XML records that need to be parsed and loaded into a database. I want to have counters which I can keep incrementing, for example, whenever a new file is received at B, and whenever a record is imported into

问题 I have a simple monitoring application that is getting some values from PerfMon counters. Even when testing on the local machine, it is taking over 30 seconds to create a new PerformanceCounter object. using System; using System.Diagnostics; namespace test_slow_perfmon { class Program { static void Main(string[] args) { Stopwatch w = new Stopwatch(); w.Start(); PerformanceCounter c = new PerformanceCounter("PhysicalDisk", "Avg. Disk Read Queue Length", "_Total", "localhost"); w.Stop();

问题 I couldn't find the ".NET CLR Memory" counter category programmatically (in c#), as in this question. Running as admin solved the issue. But why do I need to do this? Is there an alternative? I want readonly access, to see GC generation collections inside my app for profiling purposes. Preferably without having to run the app with admin privileges. Edit: I can see the Memory performance counters in the Performance Monitor tool, without running as Admin Without running as Admin, I can get a

问题 I have a C# project, where I have to both access the current workload of my processor, and ensure, that I run some specific code on every kernel of the processor. My problem is, that accessing the workload of my processor seems to prevent me from correctly assigning a thread affinity mask. I have some code here, that illustrates the problem: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.InteropServices; using System.Diagnostics;

问题 I'm trying to use a Performance Counter do determine how many bytes my application has sent or received. I followed the suggested solution found here: Calculating Bandwidth, but the instance of my application doesn’t show up in the “.NET CLR Networking” category. Exception message: "Instance 'ApplicationName[8824]' does not exist in the specified Category" (I have added <performanceCounters enabled="true"/> in my App.config and it still it cannot be found after some networking activities) So
