performancecounter

问题 I want to execute a command from command line to reset given performance counter to 0. I could write a simple "3" lines console app to do that, but wondering if VS or Windows or Windows SDK already comes with such utility. I did not find such option in either typeperf or logman. Context: Windows 7 x64 (with Admin access) Background: I use a performance counter to debug/develop/stress-test a web service. Web service increments a performance counter every time it is hit. So the scenario is to

问题 I am creating and setting up the performance counters correctly but when I delete the category, recreate the category with the same name and add/update the counters to that category, it fails to update the counters and its values. The following code runs fine for the first time but not the second time. The code to remove the "Delete category" is not needed right now but I want to be able to delete existing category each time we deploy our application. How can I permanently delete the counter

问题 I have this simple code: public void CreateCounters() { if (PerformanceCounterCategory.Exists(_categoryName)) { PerformanceCounterCategory.Delete(_categoryName); } // create logic… } works on my machine. I run it on my server, get the following stack trace: System has detected a fatal error. EXITING... NativeErrorCode: 1010 ErrorCode: -2147467259 Message: The configuration registry key is invalid TargetSite: Void RegisterFiles(System.String, Boolean) HelpLink: Source: System Stack Trace: at

问题 I have a WCF service that updates the value of two performance counters. The first is defined as NumberOfItems64, and the second as RateOfCountsPerSecond64. When I update their values (I do this several times per second), perfmon displays as expected the right value for the first counter, but always says that the value of the second counter is 0. When I debug my code, I can see that the RawValue property of the second counter is updated as expected... Here is my PowerShell code to create the

问题 I need to get some of the values that are in the windows 7 resource monitor. In particular, the memory usage, cpu and bandwidth per process. I've looked into the PerformanceCounter class and I don't see a way to drill down to the process level. The resource monitor has exactly what I am looking for, and before you ask... I know this is re-inventing the wheel but the boss wants this. I looked into WMI as well and it seems most people recommend not using it. So does anyone know how I can get at

问题 I am attempting this: using System.Diagnostics; // ... var queueCounter = new PerformanceCounter( "MSMQ Queue", "Messages in Queue", @"machinename\private$\testqueue2"); Console.WriteLine( "Queue contains {0} messages", queueCounter.NextValue().ToString()); Which came from this post: Is there a way to check how many messages are in a MSMQ Queue? There is mention of this same error, but no resolution when using PerformanceCounter. I also found mention here: Performance Counter - System

问题 For measuring execution time of methods, I've seen suggestions to use public class PerformanceInterceptor { @AroundInvoke Object measureTime(InvocationContext ctx) throws Exception { long beforeTime = System.currentTimeMillis(); Object obj = null; try { obj = ctx.proceed(); return obj; } finally { time = System.currentTimeMillis() - beforeTime; // Log time } } Then put @Interceptors(PerformanceInterceptor.class) before whatever method you want measured. Anyway I tried this and it seems to

问题 I am trying to measure the Calls Duration performance counter for a WCF service method. I have a very simple WCF service as given below. Service interface: [ServiceContract] public interface IFooService { [OperationContract] string DoSomeExpensiveOperation(); } The service implementation: public class FooService : IFooService { public string DoSomeExpensiveOperation() { Thread.Sleep(3000); return "Some valuable information"; } } When the implementation is synchronous (as given above), I can

问题 I am using the System.Data PerfomanceCounter class, and I have found some very specific examples of how to retrieve disk space or CPU usage. However I am unable to find the documentation on the possible values for: PerfomanceCounter.CategoryName PerformanceCounter.CounterName PerformanceCounter.InstanceName I can see from the class the different parameters I can pass to the constructor, but even going to the page for say CategoryName does not give me a list of available values. Can anyone
