CloudFormation
The CloudFormation engine provisions these resource types via this service:
AWS::Logs::LogGroup
See CloudFormation engine for intrinsic support and lifecycle details.
Known limitations
- Retention policies are stored but log data is not automatically expired.
- Subscription filters are stored but not triggered — destination services (Firehose/Lambda/Kinesis) receive no events.
- ECS task logs and CodeBuild build logs are NOT piped into log groups (see their service pages).
