To support a service for a UE, the QoS flow supporting the specific QoS needs to be added or modified. If the QoS flow fails to be added or modified, the user service cannot be conducted or the QoS cannot be met. So the QoS flow addition and modification need to be monitored.

Furthermore, in order to know the UE traffic pattern at SMF, it is necessary to monitor the peak and mean number of ongoing QoS flows for each granularity period.
