The DLF Streams list box lists the available DLF Steams in the store. A DLF Stream contains all the data related to one DLF Schema. In Lire, a superservice is one DLF Schema, but there are others created by analysers. For example, the www superservice has 7 related schemas. When you select one DLF Stream, you can see on the screen the number of records it contains as well as the starting and ending date of the stream.
You can use the button to remove old DLF records from the store.
The  button can be used to
          configure the stream. From this screen you can select the
          default amount of days of data to keep in the stream. Use
          the value 0 to turn on automatic cleaning
          of the stream.
        
Also from the same screen, you can select the analyser
          to use to generate each of the other schemas related to this
          DLF Stream. Select the none analyser
          to turn off creation of the related streams. If the analyser
