Exctrlst.exe: Extensible Performance Counter List
Overview | Notes | UI | Examples | Related Tools	Run Tool

Exctrlst lists all services and applications that provide registry-based performance counters on local and remote Windows 2000 and Windows XP Professional systems. It displays the names and locations of the dynamic link libraries (DLLs) that support performance counters, indicates disabled counters, and lets you enable and disable the performance counters for a service.

Unlike most performance tools, which load performance counters in order to collect data, Exctrlst displays information directly from the Performance subkeys in the registry (HKLM\SYSTEM\CurrentControlSet\Services\ServiceName\Performance. As a result, Exctrlst lists all registered performance DLLs, even those that do not load or operate properly.

Performance counter developers can use this tool to find the DLLs, basic functions, and indexes of performance counters provided by a service. Administrators can use this tool to determine which services have installed performance counters on the system and to identify counters that are disabled or do not load properly.

Exctrlst displays the following information about performance counters:

• Services and applications that provide performance counters
• Names and locations of performance counter DLLs
• Enabled and disabled performance counters
• Indexes of performance objects, counter names, and help text provided by the service
• Names of the open, collect, and close procedure of each counter DLL
• The highest index on the system used for performance counters and their help text.
