Troubleshooting the OpenAccess SDK Clients : Troubleshooting the ADO.NET Client : PerfMon Support
 

PerfMon Support

The Performance Monitor (PerfMon) utility in the Windows operating system allows you to record application parameters and review the results as a report or graph. You can also use Performance Monitor to identify the number and frequency of CLR exceptions in your applications.
The OpenAccess SDK for .NET data provider installs a set of PerfMon counters that let you tune and debug applications that use the data provider. The data provider’s counters are located in the Performance Monitor under a category name, for example, OpenAccess SDK .NET Data Provider.
The following table describes the counters that you can use to tune connections for your application.
