# Writing AWS Elemental MediaTailor logs directly to Amazon CloudWatch Logs
<a name="monitoring-cw-logs"></a>

MediaTailor produces logs that contain detailed information about session activity and ad decision server interactions, and writes them to Amazon CloudWatch. The logs provide a sequential description of activity that occurs during the session.

MediaTailor can also use vended logs for flexibility in log delivery and volume discount pricing. For information about vended logs, see [Using vended logs](vended-logs.md).
