HKLM\SYSTEM\CurrentControlSet\Services\service-name\Performance

 

Data type Range Default value

REG_DWORD

0x0–0xEE6B2800 milliseconds

The value of OpenProcedureWaitTime

Description

Defines a slow Open procedure call for these counters.

This entry tells the Performance Library (Perflib) how long the Open procedure call for these counters is expected to run. If the time specified in the value of this entry expires before the call completes, then Perfib considers the call to be abnormally slow, and it records an error in the Application Log in Event Viewer. Also, if the Configuration Flags entry requires it, then Perflib disables the counters and does not display the counters again until you manually re-enable them.

Perflib times the procedure calls of non-trusted counters to identify counters that can delay or lock performance tools during initialization. While the Collect procedure call proceeds, you cannot use the performance tools, and remote users cannot log on to the local computer.

Activation Method

To make changes to this entry effective, restart the Remote Registry Service or restart Windows.

Note

  • Timing procedure calls is one of several tests Perflib performs to maintain the integrity of the counters. To configure the Perflib test feature, use the Configuration Flags entry.

  • Perflib does not time the procedure calls of trusted performance counter dynamic-link libraries (DLLs). This entry applies only to non-trusted DLLs.

  • Perflib disables counters because of slow procedure calls only when, the 0x8 (1000) bit is set and the 0x2 (10) bit is not set in the value of Configuration Flags.

  • Perflib does not time procedure calls when the 0x4 (100) bit is set in the value of Configuration Flags.

  • Perflib disables counter by setting the value of Disable Performance Counters for that service to 1. After you have repaired or replaced the counter DLLs, you must re-enable them manually by changing the value of Disable Performance Counters to 0.

  • Some performance counters DLLs add the Collect Timeout entry to the registry. If it does not appear, you can add this entry to the registry to override the default value.

  • This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.

Tip

  • If you suspect problems with procedure calls, check the Application Log in Event Viewer. Perflib records an error in the log whenever a procedure call exceeds its limit.
