Amazon CloudWatch now sends alarm state change events to Amazon EventBridge

Now you can simply create rules in Amazon EventBridge that match specified CloudWatch alarms. Each rule supports multiple targets including AWS Lambda functions, AWS Step Functions state machines, Amazon SQS queues, Amazon Kinesis Data Streams, or Systems Manager Automation and more. For example, you can define an alarm that fires when the available disk space is running low that triggers an AWS Lambda function, via an Amazon EventBridge rule, to clean up the space.
