Performance Logs and Alerts (PLA) provides application programmers the ability to generate alert notifications based on performance counter thresholds. Programmers can also use PLA to query performance data, create event tracing sessions, capture a computer's configuration, and trace the API calls in some of the Win32 system DLLs.
PLA is designed for C and C++ developers and those writing scripts.
PLA is available starting with Windows Vista.
