To check for messages that are directly communicated to SMF service, add svc_to_svc field in sgw_service_stats query as shown below:
Query: sum(irate(sgw_service_stats{status=~"attempted"}[30s])) by (sgw_procedure_type,status, interface, svc_to_svc)
Legend: {{interface}} -> {{sgw_procedure_type}} | {{svc_to_svc}} | {{status}}
