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

**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 and the load balancer is rebalancing capacity.

**Reserved LCU**  
To determine reserved LCU utilization, you can compare the per-minute **PeakBytesPerSecond** 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.
