- Retrieves a previously logged performance measurement.

- Retrieves the performance log entry from the performance log specified by LogEntryKey.
- If it stands for a valid entry, then EFI_SUCCESS is returned and
- GaugeDataEntry stores the pointer to that entry.
-
- @param LogEntryKey The key for the previous performance measurement log entry.

- @param GaugeDataEntry The indirect pointer to the gauge data entry specified by LogEntryKey
- if the retrieval is successful.
-
- @retval EFI_SUCCESS The GuageDataEntry is successfully found based on LogEntryKey.
- @retval EFI_NOT_FOUND The LogEntryKey is the last entry (equals to the total entry number).
- @retval EFI_INVALIDE_PARAMETER The LogEntryKey is not a valid entry (greater than the total entry number).
