# Monitor Load balancer Capacity Unit reservation for your Network Load Balancer
<a name="monitor-capacity-unit-reservation"></a>

**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)\$18/60/ (10^6)/2.2.
