Metrics
Following new metric was introduced to capture the event when new chunk allocation is throttled:
Metric Name: IPAM_DP_chunk_allocation_throttled
Description: This metric captures the event when a new chunk allocation request is throttled for a UPF for a specific address-type and DNN. The new chunk allocation request is normally triggered on every address allocation request after hitting the upper threshold (80%) for the specific address-type and DNN.
Following labels are added in this metric:
-
grInstId: GR Instance ID
-
upf: UPF Key
-
addressType: Address Type (IPv4/IPv6-PD/IPv6
-
dnn: DNN Tag name
-
chunkAllocTrigger: Trigger for new chunk allocation
-
Threshold_Hit_Addr_Alloc: Threshold hit after new address allocation.
-
Threshold_Hit_DP_Monitoring: Threshold hit after pool monitoring for that UPF.
-
Insufficient_Addr_Space: If sufficient addresses are not available during IP allocation.
