WCF LOB Adapter SDK Performance Counters

WCF LOB Adapter SDK provides the following built-in performance counters to help gauge performance of the adapter.  You can view these performance counters in Performance Management Console (perfmon.msc).  Select the performance object named "ServiceModel Adapters". 

% Cache full	The percentage of cache capacity in use.
% Cache read hits	The percentage of metadata read hits in the in-memory metadata cache provided by WCF LOB Adapter SDK
Aborted Connections	The count of target system connections aborted by the adapter.
In-use Connections	The count of target system connections currently in-use.
Metadata Resolved	The number of metadata items resolved by the adapter.
Opened Connections	The count of target system connections currently opened by the adapter.
Outbound Calls	The total number of outbound calls being made.
Outbound Calls /sec	The number of outbound calls per second.
Pending Connection Requests	The number of pending target system connection requests.
Ready Connections	The count of open and available target system connections available to the adapter.

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.
