Showperf.exe: Performance Data Block Dump Utility
Overview | Notes | UI | Examples | Related Tools	Run Tool

ShowPerf loads and runs the dynamic-link libraries (DLLs) of installed performance counters on local and remote computers running Windows 2000 and Windows XP Professional, and displays unformatted data from the internal data buffers of counters that loaded successfully and are enabled on the system.

Administrators and performance counter developers can use this tool to identify counters that the system cannot load and counters that the system disables because the DLL fails the system's run-time reliability tests. They can also use Showperf to detect errors in the counter data retrieved from the performance registry.

Showperf displays the following data for counters that load successfully and are enabled on the system:

• Performance objects and object instances that are enabled on the system. (Disabled objects do not appear.)
• Index of the object in the performance registry (HKEY_PERFORMANCE_DATA).
• Performance counters for each object.
• Index of the counter in the performance registry (HKEY_PERFORMANCE_DATA).
• Counter type of each performance counter.
• Unformatted content of the data block for the performance counter.
