You can monitor the IP addresses inventory of subnets using [CNI Metrics Helper](https://github.com/aws/amazon-vpc-cni-k8s/blob/master/cmd/cni-metrics-helper/README.md). Some of the metrics available are:
 
 * maximum number of ENIs the cluster can support
 * number of ENIs already allocated
 * number of IP addresses currently assigned to Pods
 * total and maximum number of IP address available
