POInstalling a Total instance for Performance Counters
text
Body
copied!<p>VS 2005, C# 2.0, .NET 2.0/3.0, Win2003</p> <p>I'm trying to install a set of performance counters for a MultiInstance. I noticed that some system performance counter categories manage to keep a "<strong>total</strong>" alive even when there are no other instances. ASP.NET Apps 2.0.50727 is an example.</p> <p>So I've been trying to duplicate this. I created the following routine in an Installer class which I then add to a Custom Action in a setup project.</p> <pre><code>public override void Install(System.Collections.IDictionary stateSaver) { //Debugger.Break(); CounterCreationData data = new CounterCreationData("ZCounter", "ZCtrHelp", PerformanceCounterType.NumberOfItems32); PerformanceCounterCategory.Create("ZCategory", "ZCatHelp", PerformanceCounterCategoryType.MultiInstance, new CounterCreationDataCollection(new CounterCreationData[] { data })); PerformanceCounter counter = new PerformanceCounter(); counter.CategoryName = "ZCategory"; counter.CounterName = "ZCounter"; counter.InstanceName = "ZTotal"; counter.InstanceLifetime = PerformanceCounterInstanceLifetime.Global; counter.ReadOnly = false; counter.RawValue = 0; base.Install(stateSaver); } </code></pre> <p>If I uncomment the <code>Debugger.Break()</code> line, and step through, I can see the counter is actually created with the right instance name, and Visual Studio Server Explorer shows the instance along with the InstanceLifetime set to Global. I do not call the RemoveInstance() method in the setup program.</p> <p>Nevertheless, a few seconds after the setup program completes, that instance disappears from the Performance Monitor and from the VS Server Explorer. How do I make it stick? Or can I?</p>
