As Run log for Channel Assembly

The As Run log, in the CloudWatch MediaTailor/Channel/AsRunLog log group, shows information about programs and ad breaks as they play.

When you create a channel, the As Run log is disabled by default. Using the Console or the AWS Command Line Interface (AWS CLI), you can enable and disable the As Run log state for each channel in your account.

When you enable the As Run log, MediaTailor automatically creates a service-linked role that allows MediaTailor to write and manage the As Run log in your CloudWatch Logs account. For more information about service-linked roles, see Using service-linked roles for MediaTailor.
