Monitor Load balancer Capacity Unit reservation for your Network Load Balancer
Reservation Status
LCU reservation has four available status:
-
pending ‐ Indicates the reservation it is in the process of provisioning.
-
provisioned ‐ Indicates the reserved capacity is ready and available to use.
-
failed ‐ Indicates the request cannot be completed at the time.
-
rebalancing ‐ Indicates an availability zone has been added or removed and the load balancer is rebalancing capacity.
Reserved LCU
To determine reserved LCU utilization, you can compare the per-minute ProcessedBytes metric with the per-hour Sum(ReservedLCUs). To convert bytes per minute to LCU per hour, use (bytes per min)*8/60/ (10^6)/2.2.
