Lightsail data transfer quota

Hello.

Calculated as both inbound and outbound totals.
In other words, if you have a 2TB plan, a total of 2TB of inbound and outbound should be free.
If you exceed the capacity of your Lightsail instance plan, additional charges will be incurred only for outbound communication.

What does data transfer cost?

Your instance, database, and content delivery network (CDN) distribution plans include a data transfer allowance.

For Lightsail instances, both data transfer in and data transfer out of your instance count toward your data transfer allowance. If you exceed your data transfer allowance, you will only get charged for data transfer OUT from a Lightsail instance to the internet or to AWS resources using the public IP address of the instance. Both data transfer IN to Lightsail instances and data transfer OUT from a Lightsail instance when using the instance's private IP address are free beyond your data transfer allowance.

Thanks, one more question,where can I check the inbound transfer data usuage?
