Counter Name: Calls Faulted
Number of calls to this operation that returned faults. In Windows Communication Foundation (WCF) applications, service methods communicate processing error information using SOAP fault messages. SOAP faults are message types that are included in the metadata for a service operation and therefore create a fault contract that clients can use to make their execution more robust or interactive. Since SOAP faults are expressed to clients in XML form, they are highly interoperable.
