256986 Description of the Microsoft Windows Registry

SUMMARY

You can generate diagnostic information by using the logging feature available for the Quality of Service (QoS) service provider.

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

You can use the logging feature to monitor a program's usage of the QoS Application Programming Interface (API) set as well as the QoS service provider itself. Two log files are created during logging: Qossp.aid and Rapilib.aid. These files are stored in the %SystemRoot%\System32\Logfiles folder. To enable logging, you must modify the registry.

To enable QoS service provider logging, add the following value to the registry:

Value Name: EnableDebugAid
Key: HKLM\System\CurrentControlSet\Services\Rsvp\Parameters
Value Type: REG_DWORD
Valid Range: 0 - 1
Created by installation: No
Description: This key enables logging for the QoS service provider. A value of 0 generates a diagnostic log (Qossp.aid) containing information about how a program is using the generic QoS API. A value of 1 generates a diagnostic log (Rapilib.aid) that displays how well the QoS service provider itself is working.
