Automatically create and configure Amazon CloudWatch alarms for EC2 instances, RDS, and AWS Lambda using tags for standard and custom CloudWatch Metrics.
Hi ! I have this error when I test the lambda. There is the tag on the instance in the Value section that is added but it is impossible to get the CloudWatch alerts.
