The Performance Data Helper component contains a dynamic-link library (.dll) which simplifies collecting performance data from real-time data sources or performance counter log files. This component provides a level of abstraction over the performance registry interface to avoid directly extracting and formatting raw performance counter data from the performance data object blocks.

Using the performance data helper, you can complete the following tasks:

• Query what performance counters are available from the system
• Extract raw counter data locally or remotely
• Access Windows Management Instrumentation (WMI) high-performance counters through the Wbemperf.dll file, the WMI high-performance counter provider
• Set read/write permission on performance counter log files
• Calculate formatted counter values from raw counter data
• Set read/write permission on performance counter log files
