config 
    monitor nf subscriber  [ gpsi gpsi_value |imei imei_id|imsiimsi_value control { true | false }  data { true | false } target-nf { sgwu | upf } ] 
    end

  • monitor nf —Specify the NF that you want to monitor.

  • gpsi gpsi_value —Specify the subscriber GPSI.

  • imsi imsi_value —Specify the subscriber IMSI. For example: 123456789, *

  • imei imei_id —Specify the subscriber IMEI. For example: 123456789012345, *

  • control { true | false } —Specify whether to enable or disable the control event tracing.
