WCF Performance Counters can be found in categories: ServiceModelEndpoint, ServiceModelOperation and ServiceModelService.
You can enable performance counters for the adapter through the app.config configuration file of the calling application as follows:
<configuration>
<system.serviceModel>
<diagnostics performanceCountersEnabled="All" />
</system.serviceModel>
</configuration>
If you want to enable performance counters for all WCF applications, you can place the configuration settings in the Machine.config file.
