Bulk Statistics Support

The following statistics is used in the AMF collision handling.

amf_collision_stats

Description:

This set of statistics is used for tracking and debugging the AMF collision. The statistics include the name of the colliding procedure and the action taken by the collision resolver.

Sample Query:
amf_collision_stats{action_type="abort_proc1",
app_name="amf",cluster="clu001",data_center="sys001",
instance_id="0",proc1="UERegistration",
proc2="Deregistration",service_name="amf-service"} 1

When the AMF receives the De-Registration while the UE Registration procedure is in progress, the collision resolver aborts the registration procedure. It includes the names of two colliding procedures and collision resolver actions.
