Troubleshoot: Event ID 1017 – Performance Library Availability

Leave a reply

In this article, let’s discuss about the Performance Counters. They’re available as built-in to the operating system and from the non-Microsoft vendors. Both are combined and available in the Performance Library. Windows Reliability and Performance Monitor are some of the Performance Monitoring applications and they’re using the Performance Library to identify the available counters to map to the counter providers. Errors accessing the Performance Library may result in application errors when expected data cannot be found, or when expected data providers are unavailable.
Let’s have the below example.
Event Details

Product: Windows Operating System
ID: 1017
Source: Microsoft-Windows-Perflib
Version: 6.1
Symbolic Name: PERFLIB_LIBRARY_DISABLED
Message: Disabled performance counter data collection from the “%1!s!” service because the performance counter library for that service has generated one or more errors. The errors that forced this action have been written to the application event log. Correct the errors before enabling the performance counters for this service.

Diagnosing the cause
Following are the possible causes:
• A non-Microsoft DLL caused the error.
• The list of counters is corrupt.
• The Remote Registry service is not running on a remote system.
• The File and Printer Sharing firewall exception is not enabled on a remote system running Windows Vista.
• The application is running as a user with insufficient privileges.
