To get started, you can choose a maximum aggregation interval (also known as capture window) of 1 minute while creating a new flow log using the AWS Management Console, the AWS Command Line Interface (AWS CLI) or the AWS Software Development Kit (AWS SDK). Your flow logs will then be aggregated at intervals of up to 1 minute, before they are processed and published. By default, the maximum aggregation interval is 10 minutes.
There is no additional charge for flow logs with a maximum aggregation interval of 1 minute. Standard rates apply based on your choice of log destination.
