Description

For AWS::Events::Rule, CloudFormation supports !Ref to return the Rule ID and !GetAtt to return the Rule Arn.

There are cases where the Rule's name is required. For example, CloudWatch metrics for AWS::Events::Rule use the rule name as a dimension. The name can be extracted from the Rule's ID, which takes format <source event bus name>|<rule name>. Given Rule MyEventBridgeRuleResource, we get the name like as follows:

!Select [1, !Split ['|', !Ref MyEventBridgeRuleResource]]

Whilst the above is a sufficient workaround for now, may GetAtt be extended to support name retrieval in addition to ARN?

!GetAtt MyEventBridgeRuleResource.Name
