AWS used bandwidth query script (Mainly used for query free bandwidth)

README.md

You should pip install boto3 first.

Go to IAM Management Console to create access key.

Also, you should modify the instance_id and region_name in the script above.

Then, you can call get_used_bandwidth() to get used bandwidth in Byte, or just run the script to get it in GB.
