View logs

Log messages are sent to the Amazon CloudWatch log group that you created and specified in the initial set up. Each user log messages can be found in user-specific log stream in the log group. Log stream names are generated based on the user's device identifier and a user identifier. For an authenticated user, the log stream name is <device-identifier>.<user-identifier>. For an unauthenticated user, the log stream name is <device-identifier>.guest.

The device identifier is the unique identifier provided by the user's hardware device and OS. You can use the Amplify Auth category to retrieve the user identifier for a specific user if needed. You can also retrieve the user identifier by visiting the Amazon Cognito console and inspecting the User ID in User pools.
