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:
-
N4_MSG_SESSION_DELETION_REQUEST
-
N4_MSG_SESSION_ESTABLISHMENT_REQUEST
-
N4_MSG_SESSION_MODIFICATION_REQUEST
An example of the N4 interface metrics:
smf_proto_pfcp_msg_total{app_name="SMF",cluster="Local",data_center="DC",instance_id="0",
message_direction="outbound",message_name="N4_MSG_SESSION_DELETION_REQUEST",msgpriority=true,
service_name="smf-protocol",status="accepted",transport_type="origin"} 4
smf_proto_pfcp_msg_total{app_name="SMF",cluster="Local",data_center="DC",instance_id="0",
message_direction="outbound",message_name="N4_MSG_SESSION_ESTABLISHMENT_REQUEST",msgpriority=true,
service_name="smf-protocol",status="accepted",transport_type="origin"} 6
smf_proto_pfcp_msg_total{app_name="SMF",cluster="Local",data_center="DC",instance_id="0",
message_direction="outbound",message_name="N4_MSG_SESSION_MODIFICATION_REQUEST",msgpriority=true,
service_name="smf-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:
smf_gtpc_app_priority_events{app_name="SMF",cluster="Local",data_center="DC",
event_type="NumCreateBearerSuccess",instance_id="0",priority_msg="true",service_name="gtpc-ep"} 2
smf_gtpc_app_priority_events{app_name="SMF",cluster="Local",data_center="DC",
event_type="NumRxCreateBearerRes",instance_id="0",priority_msg="true",service_name="gtpc-ep"} 2
smf_gtpc_app_priority_events{app_name="SMF",cluster="Local",data_center="DC",
event_type="NumTxCreateSessionReq",instance_id="0",priority_msg="true",service_name="gtpc-ep"} 2
