N4 Statistics:
    URR : Created        :              0
          Deleted        :              0
          Queried by ID  :              0
          Queried by all :              0
          Total Queried  :              0
    FAR : Created        :              0
          Updated        :              0
          Removed        :              0
    PDR : Predef rule    :              0
Note

Statistics are cumulative, and are displayed as a total of all session managers.

The descriptions of the fields are as follows:

  • URR Created: Displays the total number of URRs created either locally or as requested by the SMF.

  • URR Deleted: Displays the total number of URRs removed either locally or as requested by the SMF.

  • URR Queried by ID: Displays the total messages received to query a subset of URRs with their specific IDs.

  • URR Queried by all: Displays the total messages received to query all the URRs of a session.

  • URR Total Queried: Displays the total number of URRs reported to the SMF in response to "Queried by ID" and "Queried by all".

  • FAR Created: Displays the total number of FARs created.

  • FAR Updated: Displays the total number of FARs updated.

  • FAR Removed: Displays the total number of FARs removed.

  • PDR Predef rule: Displays the total number of CREATE PDRs that have predefined rules set. For one predefined rule two PDRs are received, and so the counter is updated as 2.

    Note

    Total Predef counter isn’t updated when a predefined rule is removed. SMF only sends Remove PDR message, which doesn’t contain predefined rule name. Also, during HO, for exiting predef rule, PDRs are removed and created again, so it’s counted twice for the same session.
