Monitor Load balancer Capacity Unit reservation for your Network Load Balancer

Reservation status

The following are the possible status values for an LCU reservation:

  • 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.

LCU utilization

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.
