AWS CloudTrail Integration is Now Available in Amazon Lex
Amazon Lex is now integrated with AWS CloudTrail, a service that enables you to log, continuously monitor, and retain events related to API calls across your AWS infrastructure, to provide a history of API calls for your account. Amazon Lex API calls are captured from the Amazon Lex console or from your API operations using the SDKs directly. Your Amazon Lex API calls are delivered to an Amazon S3 bucket with your other AWS service records. Using the information collected by AWS CloudTrail, you can track requests made to Amazon Lex including the origination of the request, such as source IP address, the date and time the request was made, and the parameters requested.
