Class StatisticRegistry

  • public class StatisticRegistry
extends java.lang.Object
    This class replaces the previous StatisticRegistry in the cases where you do not need any sampling and history.

    This class typically does a sort of mapping between the registrations and the discovered operations or passthrough statistics.

    This class also support the generation of management metadata from the discovered statistics.

    Non thread-safe.
