Creating rules for Amazon EMR events with CloudWatch

Amazon EMR automatically sends events to a CloudWatch event stream. You can create rules that match events according to a specified pattern, and route the events to targets to take action, such as sending an email notification. Patterns are matched against the event JSON object. For more information about Amazon EMR event details, see Amazon EMR events in the Amazon CloudWatch Events User Guide.
