Meaning of WCF counters in perfmon.exe

Question

I would like to use PerfMon.exe to monitor the calls to a WCF service, but I don't understand which counter I have to use. I tried Calls and Instance but the result is always 0.
Could you explain me the meaning of counters?
Moreover, there are 3 groups of counters:

• ServiceModelEndpoint
• ServiceModelOperation
• ServiceModelService

What is their meaning?
Thank you in advance.

Answer 1

A Service can be exposed via many endpoints. A service can contain many operations.

Which counters you choose depends on what you want to monitor.

For example:

• Are you interested in how many times the http endpoint is called
• Are you interested in how many times the TakeMoneyOutOfABankAccount is called
• Are you interested in how many times the SecurityService is called
