Bulk Statistics Support

This feature introduces "failed_nf_type" label in the "smf_restep_http_msg_total" statistics to indicate the target NF from where the failure response code is sent.

Following are the example queries for peer SMF and SEPP create session procedure failure responses.

  • Create session procedure success:

    smf_restep_http_msg_total{api_name="smf_pdu_session_create",app_name="SMF",
    cluster="SMF",data_center="DC",dnn="",gr_instance_id="1",
    instance_id="0",message_direction="outbound",message_type="",
    nf_type="smf",nf_uri="",proc_name="",rat_type="",req_cause="",response_cause="",
    response_status="201",service_name="rest-ep",sess_type="", failed_nf_type=""} 1
  • Create session procedure failure response from SMF:

    smf_restep_http_msg_total{api_name="smf_pdu_session_create",app_name="SMF",
    cluster="SMF",data_center="DC",dnn="",gr_instance_id="1",
    instance_id="0",message_direction="outbound",message_type="",
    nf_type="smf",nf_uri="",proc_name="",rat_type="",req_cause="",response_cause="",
    response_status="400",service_name="rest-ep",sess_type="", failed_nf_type="smf"} 1
    
  • Create session procedure failure response from SEPP:

    
    smf_restep_http_msg_total{api_name="smf_pdu_session_create",app_name="SMF",
    cluster="SMF",data_center="DC",dnn="",gr_instance_id="1",
    instance_id="0",message_direction="outbound",message_type="",
    nf_type="smf",nf_uri="",proc_name="",rat_type="",req_cause="",response_cause="",
    response_status="400",service_name="rest-ep",sess_type="", failed_nf_type="sepp"} 1
