AWS Outposts rack supports service link interface throughput metrics

You can now monitor network throughput between your Outpost rack service link virtual interfaces (VIFs) and your local network devices using Amazon CloudWatch IfTrafficIn and IfTrafficOut metrics for Outposts. Outpost rack service link VIFs establish IP connectivity and BGP sessions between your Outpost and your local network devices for service link connectivity.
