dotnet general : PerformanceCounter(), multiple instances
Hi...
I've got some custom performance counters that can have multiple instances. I use the PerformanceCounter() constructor with the instance name parameter. The thing that puzzles me, though, is that when I look in Perfmon for those counters, the instance name I've passed in has been lowercased. Why would that be? If you look at the Processes counter, it has mixed case instances. Thanks _Mark
Hello Mark,
Is the problem only occur with all the custom performance counters? As I understand, you get correct instance name in your .NET application, but incorrect name (lowcase) in Perfmon, is my understanding right? This seems not be a programming issue, since only Perfmon has this problem. You may consult the vendor of the custom performance counters, to see if they know the problem with thier performance counters in Perfmon.

Hi Luke...
The custom performance counters are our own, using the .Net System.Diagnostics classes (PerformanceCounter, etc). We pass in an instance name of mixed case but when we look at the counters in perfmon, the instance is in all lower case. Looking at other multi-instance counters in perfmon, it's clear that *other* counters don't have their instance names case-normalized. It appears to be more a weird behavior of the .Net framework classes, though I'm scratching my head why they would do this. I was hoping someone on one of the newsgroups would know why this happens.

Hello mark,
I build a sample performance counter in VS.NET 2005 based on this article: http://support.microsoft.com/kb/317679 But I didn't find the issue. Maybe you can also test this sample on your server to see if it is a code issue or an environment issue.

Hi Luke...
I think I see your problem - you're not creating multi-instance counters, only single instance. That's not what I'm referring to. Multi-instance counters have the same structure but can have multiple instantiations as different processes use copies of them. If you replace PerformanceCounterCategory.Create("HowToCounter", "some...", CounterDatas); with PerformanceCounterCategory.Create("HowToCounter", "some...", PerformanceCounterCategoryType.MultiInstance, CounterDatas); and Dim PerfCounter As New PerformanceCounter("HowToCounter", "ThreadCounter", False) with Dim PerfCounter As New PerformanceCounter("HowToCounter", "ThreadCounter", "MixedCaseInstance", False) in the example you were using, you'll be getting a multi-instance counter this time and should see the case normalization I was referring to.
