AWS Global Accelerator now supports Amazon CloudWatch metrics
Starting today you can monitor the traffic processed by AWS Global Accelerator via Amazon CloudWatch metrics. You can now view the total number of incoming and outgoing bytes processed by your accelerator. In addition, you can view the total number of new TCP or UDP flows from clients to your application endpoints every minute. This allows you, for example, to view the geographical distribution of your user traffic and monitor how much of it is local (e.g., North America to North America) or global (e.g., Australia or India to North America). Amazon CloudWatch metrics enable you to set alarms or automate actions based on predefined thresholds and to easily build dashboards that overlay different metrics.
