| Platform SDK: Performance Monitoring |
An application that supports performance counters must have a Performance key under the Services key. The following example shows the values you should include for this key.
HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Services
\Application_Name
\Performance
Library = DLL_Name
Open = Open_Function_Name
Collect = Collect_Function_Name
Close = Close_Function_Name
The Library value provides the name of the performance DLL, and the Open, Collect, and Close values provide the names of the functions exported from the performance DLL. When a performance monitoring application requests performance data, the system uses these values to determine which performance DLLs to load and which DLL functions to call.
