Configuring conversation logs - Amazon Lex

Configuring conversation logs

You enable and disable conversation logs using the console or the conversationLogSettings field of the CreateBotAlias or UpdateBotAlias operation. You can turn on or turn off audio logs, text logs, or both. Logging starts on new bot sessions. Changes to log settings aren't reflected for active sessions.

To store text logs, use an Amazon CloudWatch Logs log group in your AWS account. You can use any valid log group. The log group must be in the same region as the Amazon Lex V2 bot. For more information about creating a CloudWatch Logs log group, see Working with Log Groups and Log Streams in the Amazon CloudWatch Logs User Guide.

To store audio logs, use an Amazon S3 bucket in your AWS account. You can use any valid S3 bucket. The bucket must be in the same region as the Amazon Lex V2 bot. For more information about creating an S3 bucket, see Creating a bucket in the Amazon Simple Storage Service Getting Started Guide.

When you manage conversation logs using the console, the console updates your service role so that it has access to the log group and S3 bucket. If you are not using the console, you must provide an IAM role with policies that enable Amazon Lex V2 to write to the configured log group or bucket.

The IAM role that you use to enable conversation logs must have the iam:PassRole permission. The following policy should be attached to the role.

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "iam:PassRole", "Resource": "arn:aws:iam::account:role/role" } ] }
