Today, AWS announces that Amazon CloudWatch Network Monitor synthetic monitoring now provides its network health indicator (NHI) for paths that reach a destination across an AWS Transit Gateway inter-Region peering connection. Amazon CloudWatch Network Monitor is a fully managed service that measures packet loss and latency for the hybrid network paths connecting your AWS-hosted applications to your destinations. The NHI helps network operators and application developers rapidly determine whether an observed degradation is within the AWS network.
Previously, the NHI covered only paths that connect through AWS Direct Connect. With this launch, hybrid architectures that route across Transit Gateway inter-Region peering receive the same rapid diagnosis, reducing the time you spend isolating the source of an issue. For these paths, the NHI reflects the health of the AWS network path up to the Transit Gateway peering connection, and Amazon CloudWatch receives the metric so you can build dashboards and set alarms.
