Is there a WCF service request queue performance counter?

Question

There is a nice ASP.NET perf counter category and set of counters that can be used to track the request queue during perf test runs. However I can't find similar set for a WCF service not hosted thru IIS. Our WCF services are run as Windows services using net-tcp protocols. I've learned that there are a couple binding parameters that control queuing (Binding.MaxConnections and Binding.ListenBacklog). It wasn't a very easy find. So I wonder going forward, is there a why to track these two values in PerfMon?

Answer 1

Under the ServiceModelService performance counter category you can find the following set of queue performance counters:

• Queue Dropped Messages
• Queue Dropped Messages Per Second
• Queued Poison Messages
• Queued Poison Messages Per Second
• Queued Rejected Messages
• Queued Rejected Messages Per Second

None of which provide the information you're looking for. The performance counter that I could find more closely related to what you want is:

• Percent of Max Concurrent Calls

Which provides the number of concurrent calls as a percent of maximum concurrent calls.
