Amazon Cognito logs information to AWS CloudTrail about user authentication activity and administrative management activity. This applies to both user pools and identity pools. For example, you can see GetId and UpdateIdentityPool events in the same trail, or UpdateAuthEventFeedback and SetRiskConfiguration events. You'll also see user pool logs for hosted UI activity that doesn't correspond to operations in the user pools API. This section has some examples of logs you might see. To understand the CloudTrail event schema for any operation, generate a request for that operation and review the events that it creates in your trail.
A trail can deliver events as log files to an Amazon S3 bucket that you specify. CloudTrail log files contain one or more log entries. An event represents a single request from any source and includes information about the requested action, the date and time of the action, request parameters, and so on. CloudTrail log files are not an ordered stack trace of the public API calls, so they do not appear in any specific order.
Example CloudTrail events for a hosted UI sign-upThe following example CloudTrail events demonstrate the information that Amazon Cognito logs when a user signs up through the hosted UI.
Amazon Cognito logs the following event when a new user navigates to the sign-in page for your app.
