IPAM pool and scope metrics
IPAM publishes data about your IPAM pools and scopes to Amazon CloudWatch. You can use these metrics to create alarms for IPAM pools to notify you if the address pools are nearing exhaustion or if resources fail to comply with allocation rules set on a pool. Creating alarms and setting up notifications with Amazon CloudWatch is outside the scope of this section. For more information, see Using Amazon CloudWatch alarms in the Amazon CloudWatch User Guide.
The metrics and dimensions that IPAM sends to Amazon CloudWatch are listed below.
