Predictable ASG and ELB names after environment rebuild

Question

My customer is trying to monitor in their ElasticBeanstalk infrastructure.

They are using Grafana with Cloudwatch and in combination with ElasticBeanstalk. Every environment rebuild results in a completely new name for the ASGs and ELBs. The filter they're building to get the right ASG and ELB for their application in Grafana is quite complex and results in them not being able to configure any alerts.

Is there a way to achieve some predictability in the ASG and ELB names for ElasticBeanstalk applications? They were expecting what they see in ECS, where the names are somewhat more stable and easy to predict from Grafana.

Accepted Answer

IMHO, you can use EBS notification feature in your case. 
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.managing.sns.html

You will receive a notification like example below:

```
    {
  "Records": [
    {
      "EventSource": "aws:sns",
      "EventVersion": "1.0",
      "EventSubscriptionArn": "arn:aws:sns:us-east-1...ElasticBeanstalkNotifications-Environment-foo-app...",
      "Sns": {
        "Type": "Notification",
        "MessageId": "111",
        "TopicArn": "arn:aws:sns:us-east-1...ElasticBeanstalkNotifications-Environment-foo-app",
        "Subject": "AWS Elastic Beanstalk Notification - New application version was deployed to running EC2 instances",
        "Message": "Timestamp: Thu May 07 23:38:22 UTC 2015
Message: Lambda Function Test: New application version was deployed to running EC2 instances.

Environment: foo-app
Application: FooApp

Environment URL: http://foo.com
RequestId: 222
NotificationProcessId: 333",
        "Timestamp": "2015-05-07T23:39:18.628Z",
        "SignatureVersion": "1",
        "Signature": "hello-sig",
        "SigningCertUrl": "https://sns.us-east-1.amazonaws.com/...",
        "UnsubscribeUrl": "https://sns.us-east-1.amazonaws.com/...",
        "MessageAttributes": {}
      }
    }
  ]
}
```

You might use the 'Environment' value in 'Message' of this notification to modify grafana's resource in Lambda
