.NET Forum / .NET Framework / New Users / May 2004PerformanceCounter & PerformanceCounterCategory on Windows 2003
We are trying to create a custom performance counter and category in .Net 1.1 with Windows 2003 and XP as our operating systems. We use the following code to do this if (PerformanceCounterCategory.Exists(categoryName) PerformanceCounterCategory.Delete(categoryName) CounterCreationData ccd = new CounterCreationData(counterName, counterHelp, PerformanceCounterType.RateOfCountsPerSecond32) CounterCreationDataCollection ccdc = new CounterCreationDataCollection() ccdc.Add(ccd) PerformanceCounterCategory perfCategory = PerformanceCounterCategory.Create(categoryName, categoryHelp, ccdc) OurLibrary.Error.AssertThrow(perfCategory.CounterExists(counterName), String.Format("Expected \"{0}\" counter to exist.", counterName)) PerformanceCounter counter = new PerformanceCounter(categoryName, counterName, false) We get a "Category does not exist" InvalidOperationException when we assert that the counter exists. perfCategory != null at this time. The PerformanceCounterCategory.Create does NOT throw. We have tried many permutations of calls to try to get this to work, but it always throws. The odd thing is that the category and counter are actually created in the perfmon utility. We can see them from .net too, but not in the process that created them. We have tried this same code on Windows 2000 boxes and it works correctly. What is the problem with the Windows 2003 and XP operating systems that cause this to fail? We have searched the newsgroups and have not seen any explanations and very few instances of this problem. Are we the only ones using the .net performance counters Thanks Frank Hi Frank, Currently I am looking for somebody who could help you on it. We will reply here with more information as soon as possible. If you have any more concerns on it, please feel free to post here. Thanks for your understanding!

Is your application winform/console application? Or does it run under Asp.net account? If it is a winform/console application, what account does it run under? Is the account administrator?

This application is being run in NUnit, so it is effectively under the logged in user accounts security context. I am logged in as a local administrator, so it is not a security issue. I have run the test with registry and NTFS security auditing turned on and get no security errors there No, we don't get a "Category does not exist" exception when creating the category. Only when trying to do something with it. The Create() call works fine. It's the assertion that the counter exists in the category that throws the exception The most odd thing about this is that the category and counter (which is created through the CounterCreationData) really are created. It's just that in code at runtime, we cannot access the counter or category directly after it's been created. The test fails, then upon next run, it succeeds because the counter and category are both there Fran ----- "Jeffrey Tan[MSFT]" wrote: ---- Hi Frank Based on my understanding, when you use PerformanceCounterCategory to create categroy, you got "Category does not exist" InvalidOperationException.

Yes, I have reproduced out your issue on my WindowXP and Windows 2003 machines. After do some research, I found that this is a know issue of our product. It looks like after creating the performance counter category we keep around some shared information that is stale so we think that the Category does not exist. The workaround is call PerformanceCounter.CloseSharedResources() static method to refresh the stale data and it should fix this issue. Thank you for your patience and cooperation.
