Tag Management

You can tag log groups, log streams, host groups, and log ingestion configurations.

If your organization has configured tag policies for LTS, add tags to log groups, log streams, log ingestion rules, and host groups based on the tag policies. If a tag does not comply with the tag policies, log group, log stream, ingestion rule, and host group creation may fail. Contact your administrator to learn more about tag policies. For details about tag policies, see Overview of a Tag Policy. For details about tag management, see Overview of a Tag.
