Performance Data Helper (PDH) provides an interface for viewing and selecting available performance counters on a system. By default, it utilizes an internal SQL database to store and read counter data. By accessing the SQL database, Performance Data Helper bypasses reading and writing registry and system values. If the SQL interface is unavailable, Performance Data Helper cannot respond to queries for performance counter values.
