      ##
      # Internal: method to send duration for a transaction
      # it checks if it can send metrics with the current transaction name
      # or a default transaction name and sets the transaction name accordingly
      #
      # === Arguments
      #
      # * +span+ the name of the current span (used to construct a transaction name if none is defined)
      # * +kvs+ A hash containing key/value pairs, only the value of :TransactionName will be relevant
      #
      # Returns the result of the block.
      #

        # later or in lower spans
