WPS OAM Support

SMF Session Gauge Counters

The "wps" label is introduced at the SMF service to account for session-level gauage counters that support WPS and non-WPS functionality.

For example:

smf_session_counters{always_on="disable",app_name="smf",cluster="smf",data_center="unknown",dnn="intershat",
instance_id="0",pdu_type="ipv4",rat_type="NR",service_name="smf-service",ssc_mode="ssc_mode_1",wps="non_wps"} 10
smf_session_counters{always_on="disable",app_name="smf",cluster="smf",data_center="unknown",dnn="intershat",
instance_id="0",pdu_type="ipv4",rat_type="NR",service_name="smf-service",ssc_mode="ssc_mode_1",wps="wps"} 20

N4 Interface Metrics

The N4 interface counters related to message priority include:

  • SESSION_DELETION_REQUEST

  • SESSION_ESTABLISHMENT_REQUEST

  • SESSION_MODIFICATION_REQUEST

An example of the N4 interface metrics:

proto_pfcp_msg_total{app_name="SMF",cluster="Local",data_center="DC",instance_id="0",
message_direction="outbound",message_name="SESSION_DELETION_REQUEST",msgpriority=true,
service_name="protocol",status="accepted",transport_type="origin"} 4
proto_pfcp_msg_total{app_name="SMF",cluster="Local",data_center="DC",instance_id="0",
message_direction="outbound",message_name="SESSION_ESTABLISHMENT_REQUEST",msgpriority=true,
service_name="protocol",status="accepted",transport_type="origin"} 6
proto_pfcp_msg_total{app_name="SMF",cluster="Local",data_center="DC",instance_id="0",
message_direction="outbound",message_name="SESSION_MODIFICATION_REQUEST",msgpriority=true,
service_name="protocol",status="accepted",transport_type="origin"} 20

GTPv2 Metrics

The GTPv2 counters related to message priority include:

  • NumCreateBearerSuccess

  • NumRxCreateBearerRes

  • NumTxCreateSessionReq

An example of the GTPv2 metrics:

gtpc_app_priority_events{app_name="SMF",cluster="Local",data_center="DC",
event_type="NumCreateBearerSuccess",instance_id="0",interface_type="S5",priority_msg="true",service_name="gtpc-ep"} 2
gtpc_app_priority_events{app_name="SMF",cluster="Local",data_center="DC",
event_type="NumRxCreateBearerRes",instance_id="0",interface_type="S5",priority_msg="true",service_name="gtpc-ep"} 2
gtpc_app_priority_events{app_name="SMF",cluster="Local",data_center="DC",
event_type="NumTxCreateSessionReq",instance_id="0",interface_type="S5",priority_msg="true",service_name="gtpc-ep"} 2

KPIs

Following KPIs are supported for this feature:

sum(policy_dynamic_pcc_rules_total{pccrule_change_type="binding_param_change",event="attempted"})
   sum(policy_dynamic_pcc_rules_total{pccrule_change_type="binding_param_change",event="success"})
  sum(policy_dynamic_pcc_rules_total{pccrule_change_type="binding_param_change",event="failure"})
