Monitoring Support

An alarm is added to indicate that a GTP-U peer for a particular UPF has gone down. The alarm data includes GTP-U peer IP and UPF IP addresses.

Use the following commands to configure alert rules related to the UPF Node Report Request.

configure 
   alerts rules group alert_group_name 
   interval-seconds seconds 
   rule rule_name 
      expression promql_expression 
      severity severity_level 
      type alert-type 
      annotationannotation_name 
      value annotation_value 
      exit 
   exit
