Updated: December 6, 2007

Applies To: Windows Server 2008

yellow

Performance counters, including those built in to the operating system and those provided by non-Microsoft vendors, are combined in the Performance Library. Performance monitoring applications such as Windows Reliability and Performance Monitor use the Performance Library to identify available counters and map to 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.
